Review result: CHANGES_REQUESTED

Summary:
This PR still introduces several blocking documentation regressions. A few pages were updated correctly, but multiple modified files now contain invalid code snippets, broken Learn links, and UWP→WinUI mapping changes that point readers to the wrong APIs.

Must-fix issues:

1. hub/apps/develop/composition/composition-native-interop.md (lines 64-65): the new C++ include directives are syntactically invalid (#include <winrt/Microsoft.UI.Dispatching.h>.h> and #include <winrt/Microsoft.UI.Input.h>.h>).
2. hub/apps/windows-app-sdk/migrate-to-windows-app-sdk/guides/mrtcore.md (line 36): the C# using directive became invalid (using Microsoft.Windows.ApplicationModel.Resources.Core;.Core;).
3. hub/apps/windows-app-sdk/migrate-to-windows-app-sdk/guides/threading.md (sections "Change ... CoreDispatcher" / "Change CoreDispatcher.RunAsync..."): UWP Windows.UI.Core.CoreDispatcher was rewritten to nonexistent Microsoft.UI.Dispatching.CoreDispatcher, and the UWP links now 404.
4. hub/apps/windows-app-sdk/migrate-to-windows-app-sdk/guides/windowing.md (intro and Change CoreWindow.Dispatcher...): UWP ApplicationView/CoreWindow references now point to Windows App SDK AppWindow docs or nonexistent Microsoft.UI.* UWP APIs, which makes the migration guidance contradictory.
5. hub/apps/windows-app-sdk/migrate-to-windows-app-sdk/api-mapping-table.md (rows around 38-50): several left-column UWP entries were corrupted (for example Windows.UI.Composition, CoreDispatcher, SystemNavigationManager, CoreTextServicesManager), producing wrong mappings and broken /uwp/api/Microsoft.UI... links.
6. hub/apps/develop/input/keyboard-events.md (around lines 356-368): several links now use /uwp/api/Microsoft.UI... (for example ICommand, TextBox, OnKeyDown), which resolves to 404.
7. hub/apps/develop/input/touch-developer-guide.md (around lines 414-418): multiple Manipulation*RoutedEventArgs links now use /uwp/api/Microsoft.UI.Xaml.Input..., which resolves to 404.
8. hub/apps/develop/input/handle-pointer-input.md (line 66 and similar references): TextBlock/RichTextBlock links now use /uwp/api/Microsoft.UI.Xaml.Controls..., which resolves to 404.

[qiutongMS]

Summary:
I found several blocking documentation issues in the current PR. The main problems are broken or incorrect API links in modified migration pages, plus a renamed Window.Current migration section that now misidentifies the UWP API and breaks inbound case-study links.

Must-fix issues:

#	File	Line/Section	Issue	Severity
1	hub/apps/develop/data/drag-and-drop.md	Lines 52, 149 (DataPackage)	The PR rewires DataPackage to /windows/windows-app-sdk/api/winrt/microsoft.windows.applicationmodel.datatransfer.datapackage, which returns 404. The WinUI drag/drop docs still refer to Windows.ApplicationModel.DataTransfer.DataPackage, so these links need to be corrected.	must-fix
2	hub/apps/windows-app-sdk/migrate-to-windows-app-sdk/guides/winui3.md	Section Change Microsoft.UI.Xaml.Window.Current to App.Window	This section now says a UWP app uses Microsoft.UI.Xaml.Window.Current, but the UWP API is Windows.UI.Xaml.Window.Current. Renaming the heading also breaks the existing #change-windowsuixamlwindowcurrent-to-appwindow links from the case-study pages.	must-fix
3	hub/apps/windows-app-sdk/migrate-to-windows-app-sdk/api-mapping-table.md	Lines 90-91 (Window.Current / Window.Dispatcher)	The left-hand UWP source entries now link to the Windows App SDK Microsoft.UI.Xaml.Window.Current / Window.Dispatcher pages instead of the UWP Windows.UI.Xaml API pages, so the mapping table points readers to the wrong source API reference.	must-fix
4	hub/apps/windows-app-sdk/migrate-to-windows-app-sdk/guides/threading.md	Line 126 (DispatcherQueue.TryEnqueue)	The DispatcherQueue.TryEnqueue link has an extra closing parenthesis in the URL (...tryenqueue))), which resolves to a 404.	must-fix

Review result: CHANGES_REQUESTED

Summary: This revision still introduces several blocking documentation regressions, including malformed links, invalid code snippets, and migration-table entries that now point the UWP side to Windows App SDK APIs.

Must-fix issues:

1. hub/apps/develop/input/handle-pointer-input.md: invalid C# snippet (Microsoft.UI.Xaml; lines without using) and malformed https://https://... sample links.
2. hub/apps/develop/input/respond-to-the-presence-of-the-touch-keyboard.md: invalid sample syntax (using Microsoft.UI.Windowing;;, #include <winrt/Microsoft.UI.Windowing>).
3. hub/apps/develop/notifications/push-notifications/wns-overview.md: broken C++ namespace line (using namespace using namespace ...).
4. hub/apps/develop/input/keyboard-events.md: invalid C++ namespace/type names (Microsoft.UI.XamlInput::..., Microsoft.UI.XamlRoutedEventArgs^, Microsoft.UI.XamlFocusState::Programmatic).
5. hub/apps/windows-app-sdk/migrate-to-windows-app-sdk/api-mapping-table.md and hub/apps/windows-app-sdk/migrate-to-windows-app-sdk/guides/windowing.md: UWP-side mapping entries now link to Windows App SDK APIs, which makes the migration tables incorrect.

[qiutongMS]

Review result: CHANGES_REQUESTED

Summary: The PR fixes many links cleanly, but several migration pages now rewrite UWP-side APIs to Windows App SDK APIs, which breaks the source→target comparisons and introduces a couple of incorrect code/link changes.

Must-fix issues:

1. hub/apps/develop/input/respond-to-the-presence-of-the-touch-keyboard.md ("Handling the Showing and Hiding events"): InputPane is still a Windows.UI.ViewManagement API. Replacing using Windows.UI.ViewManagement; / #include <winrt/Windows.UI.ViewManagement.h> with Microsoft.UI.Windowing makes the sample inconsistent with the code below (InputPane.GetForCurrentView() / Windows::UI::ViewManagement::InputPane) and non-compilable.
2. hub/apps/windows-app-sdk/migrate-to-windows-app-sdk/guides/winui3.md ("ContentDialog, and Popup"): the text now says a UWP app uses Microsoft.UI.Xaml.*, and the Popup link points to the ContentDialog page. This section should keep the UWP Windows.UI.Xaml.* types on the source side and link Popup to the Microsoft.UI.Xaml.Controls.Primitives.Popup page.
3. hub/apps/windows-app-sdk/migrate-to-windows-app-sdk/guides/windowing.md ("Event handling") and hub/apps/windows-app-sdk/migrate-to-windows-app-sdk/api-mapping-table.md: several UWP-side links/rows now point to Windows App SDK APIs (AppWindow.Changed, DidSizeChange, Windows.UI.Xaml, ContentDialog, InkCanvas, Popup). That collapses the UWP-vs-Windows-App-SDK mapping and makes the migration guidance inaccurate.
4. hub/apps/windows-app-sdk/migrate-to-windows-app-sdk/case-study-1.md and case-study-2.md: "Change Microsoft.UI.Xaml.Window.Current to App.Window" should still refer to Windows.UI.Xaml.Window.Current; otherwise the source API name is wrong.

[qiutongMS]

Summary:
I found several blocking issues in the updated docs. A few UWP source references were changed to Windows App SDK targets, which breaks the migration guidance, and one page now has malformed sample links.

Must-fix issues:

1. hub/apps/windows-app-sdk/migrate-to-windows-app-sdk/guides/windowing.md: multiple UWP-source references now point to Windows App SDK APIs (for example the UWP AppWindow column in the Window title table, the title-bar section, and AppWindow.Changed). That collapses the source and target sides of the migration guidance and makes the mappings incorrect.
2. hub/apps/windows-app-sdk/migrate-to-windows-app-sdk/guides/feature-area-guides-ovw.md: the overview now links the UWP AppWindow source term to Microsoft.UI.Windowing.AppWindow, which misstates the source API in the section summary.
3. hub/apps/develop/input/handle-pointer-input.md: the sample links near the end of the page are malformed (https://https://...) and missing closing ), so the markdown/link syntax is broken.
4. hub/apps/develop/input/guidelines-for-visualfeedback.md: the Windows.UI.Core entry in Important APIs now points to microsoft.ui.input, which is the wrong API destination.
5. hub/apps/develop/input/touch-developer-guide.md: the Windows.UI.Core entry in Important APIs now points to microsoft.ui.dispatching, which is also the wrong destination for the label shown.

Review Result: CHANGES_REQUESTED

Summary

The PR improves many WinAppSDK links, but a few edits now point readers to the wrong API family or collapse the UWP-to-Windows App SDK mapping. I can't approve the latest state as-is because those changes introduce technical inconsistencies.

Must-Fix Issues

#	File	Line/Section	Issue	Severity
1	hub/apps/windows-app-sdk/migrate-to-windows-app-sdk/api-mapping-table.md	Windows.UI.Xaml mapping rows	Several source-column entries were changed from UWP APIs to Microsoft.UI pages (Windows.UI.Xaml, ContentDialog, InkCanvas, Popup). That breaks the table's purpose: the left side is supposed to describe the UWP API being migrated, not the Windows App SDK replacement.	must-fix
2	hub/apps/develop/input/mouse-interactions.md and related input pages	Important APIs / namespace references	Multiple pages still say Windows.UI.Input or Windows.UI.Xaml.Input, but the updated links now go to Microsoft.UI.* pages. This is technically misleading because the prose and the destination no longer describe the same namespace. guidelines-for-visualfeedback.md explicitly distinguishes Windows.UI.Input from Microsoft.UI.Input, so the new link contradicts the note immediately below it.	must-fix
3	hub/apps/windows-app-sdk/migrate-to-windows-app-sdk/guides/keyboard-events.md	See also → UWP APIs	The UWP APIs subsection now links to Windows App SDK (Microsoft.UI.Xaml) pages for KeyboardAccelerator, UIElement.CharacterReceived, UIElement.KeyDown, and UIElement.KeyUp. Under that heading, those links should stay on the UWP API surface or the subsection should be renamed/restructured.	must-fix

Summary

I found several blocking documentation regressions in the latest PR state. Most changes are safe link modernizations, but a few replacements now point to the wrong API context or no longer match the surrounding prose.

Must-Fix Issues

#	File	Line/Section	Issue	Severity
1	hub/apps/windows-app-sdk/migrate-to-windows-app-sdk/api-mapping-table.md	Mapping table row for Windows.UI.Xaml	The UWP side of the mapping table now links Windows.UI.Xaml to the Microsoft.UI.Xaml docs. That breaks the comparison because both columns resolve to the Windows App SDK namespace.	must-fix
2	Multiple input docs (guidelines-for-optical-zoom.md, guidelines-for-panning.md, guidelines-for-rotation.md, guidelines-for-targeting.md, guidelines-for-textselection.md, guidelines-for-visualfeedback.md, handle-pointer-input.md, identify-input-devices.md)	Important APIs sections	The visible API names still say Windows.UI.Input / Windows.UI.Xaml.Input (and Windows.UI.Input.PointerPoint), but the links now resolve to Microsoft.UI.* pages. Either the displayed namespace text also needs to be updated, or these should keep pointing at the UWP references.	must-fix
3	hub/apps/windows-app-sdk/migrate-to-windows-app-sdk/guides/threading.md	Migrate winrt::resume_foreground (C++/WinRT)	The new cross-reference text says Change Microsoft.UI.Dispatching.CoreDispatcher to Microsoft.UI.Dispatching.DispatcherQueue, but Microsoft.UI.Dispatching.CoreDispatcher is not a real API. The source type here is Windows.UI.Core.CoreDispatcher.	must-fix
4	hub/apps/develop/notifications/push-notifications/raw-notification-overview.md	Other resources	The Raw notifications sample link now points to a Windows App SDK console sample file, but the prose still describes it as a Windows 8.1 sample to download and reuse. The destination no longer matches the description.	must-fix
5	hub/apps/windows-app-sdk/migrate-to-windows-app-sdk/what-is-supported.md	support matrix row for InkCanvas	This row says InkCanvas is not supported in 1.7, but the link now points to the WinAppSDK Microsoft.UI.Xaml.Controls.InkCanvas API page, which implies support and contradicts the row.	must-fix

[qiutongMS]

Summary

I reviewed the latest PR diff and the full content of the modified pages. Most of the link migrations look consistent, but there are still a couple of correctness issues that should be fixed before merge.

Must-Fix Issues

#	File	Line/Section	Issue	Severity
1	hub/apps/develop/input/touch-developer-guide.md	C++ code sample under the ManipulationDelta example	The updated C++ declaration Microsoft.UI.XamlMedia::TranslateTransform^ dragTranslation; is invalid namespace syntax. It drops the :: separator between Xaml and Media, so readers copying the sample will get a compile error.	must-fix
2	hub/apps/develop/input/keyboard-accelerators.md	Tooltip behavior section	The prose says MenuFlyoutItem, but the updated API link points to microsoft.ui.xaml.controls.appbarbutton. This is a wrong target for the named control and sends readers to the wrong API reference.	must-fix

[qiutongMS]

Review Result: CHANGES_REQUESTED

Summary

The PR makes useful WinAppSDK link/namespace updates, but the latest PR state still contains two reader-impacting technical issues in modified pages. One misidentifies the WinAppSDK drag-and-drop target interface, and one keeps a CoreWindow-based keyboard pattern that the API docs explicitly say does not work in WinUI 3.

Must-Fix Issues

#	File	Line/Section	Issue	Severity
1	hub/apps/develop/data/drag-and-drop.md	Line 151, section "Implementing custom drag and drop"	The table still names ICoreDropOperationTarget and links it to microsoft.ui.input.dragdrop.dragoperation. In Windows App SDK, the relevant interface is IDropOperationTarget (Microsoft.UI.Input.DragDrop.IDropOperationTarget). As written, the page points readers to the wrong type and wrong target API for implementing shell drop handling.	must-fix
2	hub/apps/develop/input/keyboard-events.md	Lines 109, 182, 222, 247, section "Modifier keys" / shortcut sample	The page still recommends and demonstrates CoreWindow.GetForCurrentThread().GetKeyState(...). The official API reference for CoreWindow.GetKeyState says: "For WinUI 3 apps, this method returns null. Use Microsoft.UI.Input.InputKeyboardSource.GetKeyStateForCurrentThread instead." That means the current guidance/sample is incorrect for the WinAppSDK audience this PR is migrating toward.	must-fix

Suggestions

#	File	Line/Section	Suggestion	Severity
1	hub/apps/develop/input/focus-navigation-programmatic.md	Multiple links in intro and examples	Consider finishing the migration consistently within this page: several related links now point to WinAppSDK types, but the main FocusManager links still point to UWP API docs. Keeping one link family per scenario would reduce reader confusion.	suggestion
2	hub/apps/develop/input/keyboard-accelerators.md	"Specify a keyboard accelerator"	Consider updating the first KeyboardAccelerator API link from the UWP constructor page to the WinAppSDK API page for consistency with the rest of the migrated links in this article.	suggestion

Page Health Assessment

File	Overall Quality	Notes
hub/apps/develop/data/drag-and-drop.md	⚠️ Needs correction	Most link migrations look reasonable, but the custom drag-and-drop target API row is still technically incorrect for Windows App SDK.
hub/apps/develop/input/keyboard-events.md	⚠️ Needs correction	The page mixes updated WinAppSDK links with a CoreWindow-based modifier-key pattern that is explicitly unsupported for WinUI 3.
hub/apps/develop/input/focus-navigation-programmatic.md	✅ Good	No blocking issue found, but migration is only partially consistent.
hub/apps/develop/input/keyboard-accelerators.md	✅ Good	No blocking issue found; one remaining UWP API link could be modernized for consistency.
Remaining modified files	✅ Good	I did not find additional blocking issues in the rest of the modified-file set from the latest PR state.

[qiutongMS]

Summary

I found two technical regressions in the migration guidance: one MRT Core code sample now uses the wrong namespace/member, and one WinRT type-mapping table now points readers to the wrong XAML interop types.

Must-Fix Issues

#	File	Line/Section	Issue	Severity
1	hub/apps/windows-app-sdk/migrate-to-windows-app-sdk/guides/mrtcore.md	Section "ResourceManager class"	The UWP sample block is now incorrect. ResourceManager.Current belongs to Windows.ApplicationModel.Resources.Core, not Microsoft.Windows.ApplicationModel.Resources.Core, and the Windows App SDK migration target is using Microsoft.Windows.ApplicationModel.Resources; var currentResourceManager = new ResourceManager();. As written, the code mixes UWP and Windows App SDK APIs and will mislead readers.	must-fix
2	hub/apps/develop/platform/csharp-winrt/net-mappings-of-winrt-types.md	Tables under "Mappings for WinRT types in the Windows SDK"	TypeName and TypeKind were changed to Microsoft.UI.Xaml.Interop, but WinUI 3/.NET docs still project these as Windows.UI.Xaml.Interop types (or System.Type in .NET projections). Only IBindable* moved to Microsoft.UI.Xaml.Interop; these two rows are now technically inaccurate.	must-fix

[qiutongMS]

Summary

I found two blocking issues in the current PR state: one technical error in the C#/WinRT mapping table, and one set of misleading sample-link replacements across the input articles.

Must-Fix Issues

#	File	Line/Section	Issue	Severity
1	hub/apps/develop/platform/csharp-winrt/net-mappings-of-winrt-types.md	Section "Mappings for WinRT types in the Windows SDK"	IBindableIterable and IBindableVector were changed to Microsoft.UI.Xaml.Interop, but this table is explicitly for Windows SDK mappings. That makes the section internally inconsistent and changes the documented C#/WinRT mapping.	must-fix
2	hub/apps/develop/input/handle-pointer-input.md; hub/apps/develop/input/keyboard-events.md; hub/apps/develop/input/touch-developer-guide.md	Samples sections	Multiple distinct sample labels now point to the same generic WindowsAppSDK-Samples/Samples/Input/cs-winui folder (and one single WinUI Gallery XAML page). For example, the "Low latency input sample" and "User interaction mode sample" links no longer lead to matching samples, so readers are sent to unrelated content.	must-fix

[qiutongMS]

Summary

The PR makes useful UWP→WinAppSDK link and namespace updates, but two modified pages now contain C++ examples that mix WinUI 3 namespaces with C++/CX syntax. Those snippets are not valid WinUI 3 guidance and should be fixed before merge.

Must-Fix Issues

#	File	Line/Section	Issue	Severity
1	hub/apps/develop/input/keyboard-events.md	Sections "Defining a keyboard event handler" and "Shortcut keys example"	The updated C++ examples now use Microsoft::UI::* types together with C++/CX syntax such as Platform::Object^ and KeyRoutedEventArgs^. WinUI 3 / Windows App SDK guidance should use C++/WinRT syntax; this hybrid form will not compile and gives readers an invalid migration pattern.	must-fix
2	hub/apps/develop/input/touch-developer-guide.md	Section "Manipulation events"	Microsoft::UI::Xaml::Media::TranslateTransform^ dragTranslation; mixes a WinUI 3 namespace with C++/CX hat syntax. As written, the sample is not valid WinUI 3 C++ guidance and should be rewritten consistently (for example, as C++/WinRT) or left as UWP/C++/CX.	must-fix

[qiutongMS]

Summary

The PR makes useful WinUI 3 link and terminology updates, but the resulting pages still contain a couple of reader-facing inconsistencies that would mislead someone following the migrated guidance.

Must-Fix Issues

#	File	Line/Section	Issue	Severity
1	hub/apps/develop/input/keyboard-events.md	Section "Shortcut keys example"	The prose now tells readers to use InputKeyboardSource.GetKeyStateForCurrentThread for WinUI 3, but the C++ sample in the same section still uses CoreWindow::GetForCurrentThread()->GetKeyState(...). That leaves the example set internally inconsistent and still points WinUI 3 C++ readers at the old pattern.	must-fix
2	hub/apps/develop/input/handle-pointer-input.md	Section "Get pointer properties"	Earlier in the page, the pointer guidance was migrated to Microsoft.UI.Input / Microsoft.UI.Xaml.Input, but this section still says to use Windows.UI.Input.PointerPoint and links to the UWP PointerRoutedEventArgs APIs. That contradiction makes the updated migration guidance unreliable.	must-fix

Suggestions

#	File	Line/Section	Suggestion	Severity
1	hub/apps/develop/data/drag-and-drop.md	Section "Enable drag and drop reordering within ListViews"	Consider replacing "CanDrop API" with the actual property name used in the article (AllowDrop) or rephrasing the sentence. As written, it refers to an API name that the page doesn't otherwise define.	suggestion

[qiutongMS]

Summary

The PR makes useful WinAppSDK link updates, but at least two modified input pages are now only partially migrated and still send readers back to UWP API docs for the same API families. That leaves the pages internally inconsistent and undermines the intended UWP→WinAppSDK migration.

Must-Fix Issues

#	File	Line/Section	Issue	Severity
1	hub/apps/develop/input/focus-navigation-programmatic.md	Intro / "Find a focus candidate within a scope"	The page now mixes UWP FocusManager/FindNextElement links with Microsoft.UI types in the same guidance flow. WinAppSDK docs exist for TryMoveFocus, FindNextElement, and FindNextElementOptions members, so readers are currently bounced between Windows.UI.Xaml and Microsoft.UI.Xaml for the same API surface.	must-fix
2	hub/apps/develop/input/handle-pointer-input.md	"Pointer events" / "Handle pointer events"	The page updates Important APIs and code samples to Microsoft.UI, but the event table and explanatory prose still link PointerPressed/Released/CapturePointer and related APIs to Windows.UI.Xaml pages. WinAppSDK docs exist for these APIs, so the page no longer provides a coherent WinAppSDK version of the guidance.	must-fix

[qiutongMS]

Summary

I found one blocking issue in the updated docs: a newly added Windows App SDK API link in handle-pointer-input.md resolves to 404. The other modified pages look coherent and their updated links were reachable in spot checks.

Must-Fix Issues

#	File	Line/Section	Issue	Severity
1	hub/apps/develop/input/handle-pointer-input.md	Section "Pointer events" (around line 118)	The new link for IsInContact points to /windows/windows-app-sdk/api/winrt/microsoft.ui.input.pointerpointproperties.isincontact, which returns 404. Microsoft Learn exposes this member under PointerPoint.IsInContact instead, so the page currently sends readers to a broken API reference.	must-fix

[qiutongMS]

Summary: I reviewed the latest PR diff and the full contents of all modified pages. The link migrations and terminology updates are technically sound, the added/updated documentation links resolve successfully, and I did not find any blocking correctness or coherence issues in the changed pages.

[qiutongMS]

Review Result: CHANGES_REQUESTED

Summary

Reviewed the full latest diff for PR #43. Most link migrations look correct and the added/modified Windows App SDK links I spot-checked resolved successfully, but three modified pages still mix UWP API targets with Windows App SDK targets in the same migrated sections, which leaves the migration internally contradictory for WinUI 3 readers.

Must-Fix Issues

#	File	Line/Section	Issue	Severity
1	hub/apps/develop/input/focus-navigation-programmatic.md	Navigation focus events; GotFocus and LostFocus events; GettingFocus and LosingFocus events	The page now starts migrating to Microsoft.UI.Xaml.Input.FocusManager, but these later sections still send readers to UWP API pages for NoFocusCandidateFound, GotFocus, LostFocus, GettingFocus, LosingFocus, Control.Focus, TryMoveFocus, and related event args. Microsoft.UI equivalents exist, so the page is still internally contradictory after this migration pass.	must-fix
2	hub/apps/develop/input/focus-navigation.md	XYFocusKeyboardNavigation; Tab navigation	The updated text still links XYFocusKeyboardNavigation and Control.TabNavigation to UWP pages while the same paragraphs now use Windows App SDK enum/control links. Because WinAppSDK API pages exist for these members, the migrated section still points readers at the wrong API family.	must-fix
3	hub/apps/develop/input/keyboard-events.md	Keyboard events and focus; Virtual keys; Modifier keys	The modified prose mixes Microsoft.UI.* links with UWP KeyDown/KeyUp/Focus links in the same WinUI 3 guidance. That contradiction leaves the page only partially migrated and still routes readers to UWP docs for APIs that have Windows App SDK reference pages.	must-fix

Suggestions

#	File	Line/Section	Suggestion	Severity
1	hub/apps/develop/input/touch-developer-guide.md	Important APIs / surrounding sections	After the must-fix pages are corrected, consider doing one more pass for the other touched input pages to remove remaining mixed UWP-vs-Windows App SDK API references where WinAppSDK pages now exist.	suggestion

[qiutongMS]

Fixed the 3 must-fix issues: resolved mixed UWP/WinAppSDK links in focus-navigation-programmatic.md, focus-navigation.md, and keyboard-events.md. All remaining /uwp/api/windows.ui.xaml.* links have been updated. Please re-review.

[qiutongMS]

Re-review complete on the latest diff.

Summary:

• The 3 previously flagged mixed UWP/WinAppSDK link issues are resolved in:
  • hub/apps/develop/input/focus-navigation-programmatic.md
  • hub/apps/develop/input/focus-navigation.md
  • hub/apps/develop/input/keyboard-events.md
• I checked the full latest diff and sampled the full modified pages for consistency.
• Reachability check for modified links passed (the only initial 404s were parsing artifacts on previous-versions URLs; the real links resolve).

Must-fix:

1. hub/apps/develop/input/touch-developer-guide.md (manipulation events table, around lines 413-418)
   • The newly updated Manipulation*RoutedEventArgs rows now point to WinAppSDK pages, but the event links in the same descriptions still point to UWP Windows.UI.Xaml.UIElement event pages (/uwp/api/...manipulationstarted, ...manipulationdelta, ...manipulationinertiastarting, ...manipulationcompleted).
   • This reintroduces the same mixed UWP/WinAppSDK linking pattern this PR is fixing elsewhere. These event links should be switched to the corresponding WinAppSDK microsoft.ui.xaml.uielement.* pages for consistency.

Re-review complete on the latest diff.

The touch-developer-guide.md manipulation-event mixed links are fixed. However, there are still remaining mixed UWP/WinAppSDK links in other modified files:

1. hub/apps/develop/input/handle-pointer-input.md

   • Several handler-description bullets still link to UWP Windows.UI.Xaml.UIElement event pages (PointerEntered, PointerWheelChanged, PointerExited, PointerCanceled, PointerCaptureLost) while the surrounding page now uses WinAppSDK Microsoft.UI.Xaml links for the same pointer APIs.

2. hub/apps/develop/input/keyboard-accelerators.md

   • In Specify a keyboard accelerator, KeyboardAccelerator still links to /uwp/api/windows.ui.xaml.input.keyboardaccelerator.-ctor even though the rest of the page has been migrated to WinAppSDK Microsoft.UI.Xaml.Input.KeyboardAccelerator links.

3. hub/apps/develop/input/guidelines-for-optical-zoom.md

   • The Important APIs block still links Input (XAML) to UWP /uwp/api/Windows.UI.Xaml.Input, while the page now also links to WinAppSDK ScrollViewer. That leaves the page mixed between UWP XAML docs and WinAppSDK docs.

Because those mixed links remain, this PR still isn't ready to approve.

Final re-review complete on the latest diff.

I re-checked the full current PR and the previous mixed-link fixes are in place. However, I still found 2 remaining mixed UWP/WinAppSDK links in non-migration content:

1. hub/apps/develop/input/keyboard-accelerators.md

   • In Specify a keyboard accelerator, KeyboardAccelerator still links to /uwp/api/windows.ui.xaml.input.keyboardaccelerator.-ctor.
   • I verified the WinAppSDK target is reachable: /windows/windows-app-sdk/api/winrt/microsoft.ui.xaml.input.keyboardaccelerator.-ctor returns 200, so this one should still be migrated.

2. hub/apps/develop/input/handle-pointer-input.md

   • In Primary pointer, IsPrimary and PointerPointProperties still link to UWP pages:
     • /uwp/api/windows.ui.input.pointerpointproperties.isprimary
     • /uwp/api/windows.ui.input.pointerpointproperties
   • I verified the WinAppSDK equivalents are also reachable and should be used for consistency:
     • /windows/windows-app-sdk/api/winrt/microsoft.ui.input.pointerpointproperties.isprimary
     • /windows/windows-app-sdk/api/winrt/microsoft.ui.input.pointerpointproperties

Because those two mixed links remain, this PR is not ready for final approval yet.

Final re-review complete on the latest diff.

I checked the modified PR files for remaining /uwp/api/ links and tested whether corresponding WinAppSDK targets resolve on Learn. There are still remaining UWP links with valid WinAppSDK targets, so I can’t approve yet.

Remaining findings:

1. hub/apps/develop/input/guidelines-for-optical-zoom.md

   • /uwp/api/Windows.UI.Input has a valid WinAppSDK target: /windows/windows-app-sdk/api/winrt/microsoft.ui.input

2. hub/apps/develop/input/guidelines-for-visualfeedback.md

   • /uwp/api/Windows.UI.Input has a valid WinAppSDK target: /windows/windows-app-sdk/api/winrt/microsoft.ui.input

3. hub/apps/develop/input/identify-input-devices.md

   • /uwp/api/Windows.UI.Input has a valid WinAppSDK target: /windows/windows-app-sdk/api/winrt/microsoft.ui.input

4. hub/apps/windows-app-sdk/migrate-to-windows-app-sdk/guides/threading.md

   • /uwp/api/windows.ui.xaml.controls.page has a valid WinAppSDK target: /windows/windows-app-sdk/api/winrt/microsoft.ui.xaml.controls.page
   • /uwp/api/windows.ui.xaml.dependencyobject.dispatcher has a valid WinAppSDK target: /windows/windows-app-sdk/api/winrt/microsoft.ui.xaml.dependencyobject.dispatcher

5. hub/apps/windows-app-sdk/migrate-to-windows-app-sdk/guides/winui3.md

   • /uwp/api/windows.ui.xaml.controls.contentdialog has a valid WinAppSDK target: /windows/windows-app-sdk/api/winrt/microsoft.ui.xaml.controls.contentdialog
   • /uwp/api/windows.ui.xaml.controls.primitives.popup has a valid WinAppSDK target: /windows/windows-app-sdk/api/winrt/microsoft.ui.xaml.controls.primitives.popup
   • /uwp/api/windows.ui.xaml.window.current has a valid WinAppSDK target: /windows/windows-app-sdk/api/winrt/microsoft.ui.xaml.window.current

I did not flag remaining UWP links where I could not confirm a valid WinAppSDK counterpart.

[qiutongMS]

Ran a bulk scripted audit across all PR #43 markdown files (excluding migrate-to-windows-app-sdk/*). The script scanned Windows.UI.Xaml/Input/Composition/Text UWP API links, HEAD-checked WinAppSDK replacements, and found no additional replaceable links under those rules. Remaining UWP links in these files are either intentional shared WinRT namespaces or namespaces without valid WinAppSDK targets.

[qiutongMS]

Final re-review complete.

With the clarified scope, I found no remaining blockers:

• No remaining replaceable /uwp/api/windows.ui.xaml|input|composition|text links that need migration in the PR files.
• Remaining /uwp/api/ links fall into the accepted categories you described:
  1. shared WinRT APIs intentionally kept,
  2. migration-guide comparison content,
  3. cases without a valid WinAppSDK replacement.

From a documentation-review perspective, this PR is approved.
