Prerequisites

Requirement	Version	Notes
.NET SDK	10.0+	`net10.0-windows10.0.26100.0` target framework
Windows SDK	10.0.26100.57	Set via `WindowsSdkPackageVersion` in App csproj
Windows	10/11 x64	WPF + Windows-specific P/Invoke
Visual Studio (optional)	2022+	Not required; `dotnet` CLI suffices

Minimum supported OS: Windows 10 1809 (build 17763), set via SupportedOSPlatformVersion in the App csproj.

All native DLLs, driver installers, and model assets are included in the repository. No external downloads needed.

Build Commands

Debug Build

dotnet build -c Debug

Output: PadForge.App/bin/Debug/net10.0-windows10.0.26100.0/win-x64/

Suitable for development and debugging. Not deployable. Produces loose DLLs and requires the .NET runtime.

Release Build

dotnet build -c Release

Output: PadForge.App/bin/Release/net10.0-windows10.0.26100.0/win-x64/

Not deployable. Use dotnet publish for deployment.

Publish (Portable Deployment)

dotnet publish -c Release
# or explicitly:
dotnet publish PadForge.App/PadForge.App.csproj -c Release

Output: PadForge.App/bin/Release/net10.0-windows10.0.26100.0/win-x64/publish/

File	Description
`PadForge.exe`	~102 MB, single-file self-contained
`SDL3.dll`	SDL3 native library (content item)
`libusb-1.0.dll`	WinUSB for Switch 2 Pro Controller (content item)
`gamecontrollerdb_padforge.txt`	Custom SDL gamepad mappings (content item)

Critical: Always use dotnet publish for deployment, never dotnet build. The project is configured for single-file self-contained publish. dotnet build produces non-functional multi-file output.

Single-File Publish Configuration

The App csproj defines these publish properties:

<!-- Single-file portable publish: dotnet publish -c Release -->
<PropertyGroup>
  <RuntimeIdentifier>win-x64</RuntimeIdentifier>
  <PublishSingleFile>true</PublishSingleFile>
  <SelfContained>true</SelfContained>
  <IncludeNativeLibrariesForSelfExtract>true</IncludeNativeLibrariesForSelfExtract>
  <EnableCompressionInSingleFile>true</EnableCompressionInSingleFile>
  <DebugType>embedded</DebugType>
</PropertyGroup>

Property	Value	Effect
`RuntimeIdentifier`	`win-x64`	Targets 64-bit Windows only
`PublishSingleFile`	`true`	Bundles all managed assemblies into one exe
`SelfContained`	`true`	Embeds .NET 10 runtime (no install needed on target)
`IncludeNativeLibrariesForSelfExtract`	`true`	Packs native DLLs into the exe; extracted to temp dir at runtime
`EnableCompressionInSingleFile`	`true`	Compresses the bundle to reduce exe size
`DebugType`	`embedded`	Embeds debug symbols in assemblies (no `.pdb` files); preserves stack traces for crash diagnostics

Note: RuntimeIdentifier is set unconditionally (not only during publish), so dotnet build also targets win-x64 and produces a RID-specific output folder.

Project Configuration Details

PadForge.App.csproj

<PropertyGroup>
  <OutputType>WinExe</OutputType>
  <TargetFramework>net10.0-windows10.0.26100.0</TargetFramework>
  <SupportedOSPlatformVersion>10.0.17763.0</SupportedOSPlatformVersion>
  <WindowsSdkPackageVersion>10.0.26100.57</WindowsSdkPackageVersion>
  <RootNamespace>PadForge</RootNamespace>
  <AssemblyName>PadForge</AssemblyName>
  <UseWPF>true</UseWPF>
  <UseWindowsForms>true</UseWindowsForms>  <!-- For NotifyIcon system tray -->
  <LangVersion>latest</LangVersion>
  <Nullable>disable</Nullable>
  <ImplicitUsings>enable</ImplicitUsings>
  <GenerateAssemblyInfo>false</GenerateAssemblyInfo>  <!-- Manual AssemblyInfo.cs -->
</PropertyGroup>

Key settings:

Property	Value	Purpose
`TargetFramework`	`net10.0-windows10.0.26100.0`	.NET 10 + Windows SDK 26100 (Win 11 24H2). Enables WinRT APIs.
`SupportedOSPlatformVersion`	`10.0.17763.0`	Minimum OS: Windows 10 1809
`WindowsSdkPackageVersion`	`10.0.26100.57`	Pins Windows SDK NuGet package version
`UseWindowsForms`	`true`	`NotifyIcon` system tray only (not WinForms UI)
`GenerateAssemblyInfo`	`false`	Uses manual `Properties/AssemblyInfo.cs`
`Nullable`	`disable`	Nullable reference types not used

WinForms implicit using removal. Prevents System.Drawing / System.Windows.Forms ambiguity with WPF types:

<ItemGroup>
  <Using Remove="System.Drawing" />
  <Using Remove="System.Windows.Forms" />
</ItemGroup>

PadForge.Engine.csproj

<PropertyGroup>
  <TargetFramework>net10.0-windows</TargetFramework>
  <RootNamespace>PadForge.Engine</RootNamespace>
  <AssemblyName>PadForge.Engine</AssemblyName>
  <LangVersion>latest</LangVersion>
  <Nullable>disable</Nullable>
  <ImplicitUsings>enable</ImplicitUsings>
  <GenerateAssemblyInfo>false</GenerateAssemblyInfo>
  <DebugType>embedded</DebugType>
</PropertyGroup>

The Engine targets net10.0-windows (no specific SDK version needed). Zero NuGet dependencies. All SDL3 and system interop uses raw [DllImport] P/Invoke.

Assembly Versioning

Versions are set manually in Properties/AssemblyInfo.cs (both projects set GenerateAssemblyInfo to false).

Project	File	Current Version
PadForge.App	`PadForge.App/Properties/AssemblyInfo.cs`	2.1.0.0
PadForge.Engine	`PadForge.Engine/Properties/AssemblyInfo.cs`	2.0.0.0

App and Engine versions are independent. App tracks user-facing releases, Engine tracks breaking API changes. Both AssemblyInfo files also include metadata attributes (AssemblyTitle, AssemblyCompany, AssemblyCopyright, Guid, etc.).

Important: Do not bump versions unless preparing a release. GitHub Releases use git tag names (e.g., v2.0.0-beta3) as the version identifier, not AssemblyVersion.

NuGet Dependencies

PadForge.App

Package	Version	Source	Purpose
ModernWpfUI	0.9.6	nuget.org	Fluent Design theme for WPF (dark mode, NavigationView, controls)
HelixToolkit.Core.Wpf	2.27.3	nuget.org	3D viewport rendering (OBJ model loading, camera, lighting)
CommunityToolkit.Mvvm	8.2.2	nuget.org	MVVM: `ObservableObject`, `RelayCommand`, `[ObservableProperty]`
Nefarius.HIDMaestro	1.21.256	nuget.org	HIDMaestro virtual Xbox and PlayStation controller client API
NAudio.Wasapi	2.2.1	nuget.org	WASAPI loopback audio capture for bass-driven rumble detection
Microsoft.Windows.Devices.Midi2	1.0.16-rc.3.7	nuget-local/	Windows MIDI Services SDK for virtual MIDI device creation

PadForge.Engine

No NuGet dependencies. All SDL3 and system interop is via raw P/Invoke.

Local NuGet Source (`nuget-local/`)

The Windows MIDI Services SDK is not on nuget.org. The .nupkg is stored locally:

nuget-local/Microsoft.Windows.Devices.Midi2.1.0.16-rc.3.7.nupkg

nuget.config at the solution root registers this folder as a package source:

<configuration>
  <packageSources>
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" />
    <add key="local" value="nuget-local" />
  </packageSources>
</configuration>

Both nuget.config and nuget-local/ must be present alongside PadForge.sln for dotnet restore to succeed.

Native DLLs (Content Items)

Copied alongside PadForge.exe in the output via Content + CopyToOutputDirectory. Not embedded inside the single-file exe.

SDL3.dll and libusb-1.0.dll

<Content Include="Resources\SDL3\x64\SDL3.dll" Link="SDL3.dll"
         Condition="Exists('Resources\SDL3\x64\SDL3.dll')">
  <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
</Content>
<Content Include="Resources\SDL3\x64\libusb-1.0.dll" Link="libusb-1.0.dll"
         Condition="Exists('Resources\SDL3\x64\libusb-1.0.dll')">
  <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
</Content>

Link="SDL3.dll". Flattens to output root (next to PadForge.exe) instead of preserving the subdirectory path.
Condition="Exists(...)". Build succeeds even if the DLL is absent (e.g., fresh clone).
SDL3.dll is a custom fork built from SDL3-build/SDL/ with WinUSB support for Switch 2 Pro Controller. See SDL3 Integration for build instructions.
libusb-1.0.dll provides WinUSB access for Switch 2 Pro Controller communication.

Source location: PadForge.App/Resources/SDL3/x64/

gamecontrollerdb_padforge.txt

<Content Include="gamecontrollerdb_padforge.txt">
  <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
</Content>

Custom SDL gamepad mapping database with PadForge-specific entries (e.g., DualShock 3 via DsHidMini SDF). Loaded by SDL3 at runtime. Community mappings can be submitted via the GitHub issue template.

Source location: PadForge.App/gamecontrollerdb_padforge.txt

Embedded Resources

Compiled into the assembly. Not visible as separate files in the output.

Driver Installers (EmbeddedResource)

<EmbeddedResource Include="Resources\HidHide_1.5.230_x64.exe" />

Resource	Purpose
`HidHide_1.5.230_x64.exe`	HidHide installer. Hides physical controllers from other applications

The HIDMaestro user-mode driver is installed by a separate bundled installer that DriverInstaller runs on first launch. The driver is not embedded in the EXE. The OpenXInput shim (xinput1_4.dll only) ships as <Content> and is bundled into the single-file EXE via IncludeNativeLibrariesForSelfExtract. devobj.dll is deliberately not shipped — see Driver Installation Internals for why a bundled stub would crash HID class enumeration. The Windows MIDI Services SDK is installed on demand from the Microsoft Store or installer when the user requests MIDI VC support.

PadForge v2's vJoy and ViGEmBus installers are no longer bundled. v3 detects either driver on first launch and offers to uninstall via the legacy driver cleanup dialog. See Driver Installation Internals.

3D Model Assets (EmbeddedResource)

<!-- 3D controller model assets (adapted from Handheld Companion, CC BY-NC-SA 4.0) -->
<EmbeddedResource Include="3DModels\**\*.obj" />

OBJ mesh files for 3D controller visualization. Loaded at runtime via ControllerModelBase.LoadModel().

Directory	Contents
`3DModels/XBOX360/`	31 OBJ files (Xbox 360 controller parts)
`3DModels/DS4/`	36 OBJ files (DualShock 4 controller parts)

Web Controller Assets (EmbeddedResource)

<!-- Web controller frontend assets (embedded, served by WebControllerServer) -->
<EmbeddedResource Include="WebAssets\**\*" />

HTML/CSS/JS for the browser-based virtual controller. Served by the embedded Kestrel web server at runtime.

File	Purpose
`WebAssets/index.html`	Landing page
`WebAssets/controller.html`	Virtual gamepad UI
`WebAssets/css/controller.css`	Gamepad styling
`WebAssets/js/controller_client.js`	WebSocket client logic
`WebAssets/js/nipplejs.min.js`	Virtual joystick library

Localization Strings (EmbeddedResource)

<EmbeddedResource Update="Resources\Strings\Strings.resx">
  <Generator>PublicResXFileCodeGenerator</Generator>
  <LastGenOutput>Strings.Designer.cs</LastGenOutput>
</EmbeddedResource>

Resource files for multilingual UI support:

File	Language
`Strings.resx`	English (default/fallback)
`Strings.de.resx`	German
`Strings.es.resx`	Spanish
`Strings.fr.resx`	French
`Strings.it.resx`	Italian
`Strings.ja.resx`	Japanese
`Strings.ko.resx`	Korean
`Strings.nl.resx`	Dutch
`Strings.pt-BR.resx`	Brazilian Portuguese
`Strings.zh-Hans.resx`	Simplified Chinese

The default Strings.resx uses PublicResXFileCodeGenerator to produce Strings.Designer.cs for strongly-typed access via Strings.PropertyName. Satellite .resx files follow standard .NET localization conventions and compile into satellite assemblies automatically.

2D Model Assets (Resource)

<!-- 2D controller model assets (Gamepad-Asset-Pack by AL2009man, MIT license) -->
<Resource Include="2DModels\**\*.png" />

PNG overlay images for 2D controller schematic view (DS4/ and XBOX360/ parts). Uses Resource (not EmbeddedResource) so they load as WPF pack URIs (pack://application:,,,/2DModels/...).

Other Resources

<Resource Include="Resources\Xbox Series Controller - Front.png" />
<Resource Include="Resources\Xbox Series Controller - Top.png" />
<Content Include="Resources\PadForge.ico" />

Resource	Purpose
Controller PNGs	Mapping UI images
`PadForge.ico`	Application icon (via `<ApplicationIcon>` in csproj)
`Resources/ControllerIcons.xaml`	XAML vector icon definitions (resource dictionary)

CI/CD (GitHub Actions)

Workflow: .github/workflows/build.yml

Triggers

on:
  push:
    branches: [v2-dev]
  pull_request:
    branches: [v2-dev]
  workflow_dispatch:

Runs on every push/PR to v2-dev and on manual trigger.

Build Steps

Checkout. actions/checkout@v4, fetch-depth: 0 (full history for commit counting)
Setup .NET. actions/setup-dotnet@v4, dotnet-version: 10.x
Publish. dotnet publish PadForge.App/PadForge.App.csproj -c Release
Upload artifact. Publish directory as PadForge_r{COMMIT_COUNT}@{COMMIT_SHORT}

Automatic Releases (push to v2-dev only)

On push (not PR), the workflow creates two GitHub releases:

Release	Behavior
`archive-v2-dev`	Accumulates every build as `PadForge_r{N}@{SHA}.zip`. Uses `--clobber` for latest upload; preserves tag across builds.
`latest-v2-dev`	Recreated on every push (old release deleted first). Contains `PadForge.zip` with the most recent build. The "always current" download link.

Both are marked --prerelease and cross-link to each other in their notes.

Artifact Naming

Format: PadForge_r{COMMIT_COUNT}@{7-char COMMIT_SHA} (e.g., PadForge_r342@f35bb36)

Environment Variables

env:
  DOTNET_NOLOGO: true
  DOTNET_CLI_TELEMETRY_OPTOUT: true

Formal Releases

Created manually via gh release create with a version tag (e.g., v2.0.0, v2.1.0-beta1). See Release Workflow below.

Deployment

PadForge is portable. No installer required.

Local Deployment

Copy the publish output to any folder:

cp PadForge.App/bin/Release/net10.0-windows10.0.26100.0/win-x64/publish/PadForge.exe C:\PadForge\PadForge.exe

Required companion files (placed automatically by dotnet publish):

File	Required	Purpose
`SDL3.dll`	Yes	SDL3 native library
`libusb-1.0.dll`	Yes	WinUSB for Switch 2 Pro Controller
`gamecontrollerdb_padforge.txt`	Optional	SDL3 gamepad mappings (enhances device recognition)

Development Deploy Scripts

tools/deploy.ps1              # Build, publish, copy to C:\PadForge
tools/deploy_and_restart.ps1  # Deploy + kill running instance + restart

First Run

PadForge creates PadForge.xml alongside the executable to store settings, mappings, and profiles.

PadForge always requests administrator privileges on startup (declared in app.manifest as requireAdministrator). HIDMaestro / HidHide / MIDI Services management runs inside the already-elevated process.

Release Workflow

1. Update Version (if needed)

PadForge.App/Properties/AssemblyInfo.cs. AssemblyVersion + AssemblyFileVersion
PadForge.Engine/Properties/AssemblyInfo.cs. Only if Engine API changed

2. Build

dotnet publish -c Release

3. Deploy and Test

cp PadForge.App/bin/Release/net10.0-windows10.0.26100.0/win-x64/publish/PadForge.exe C:\PadForge\PadForge.exe

Run C:\PadForge\PadForge.exe and verify functionality.

4. Commit and Push

git add -A
git commit -m "Release vX.Y.Z"
git push

5. Create Binary Zip

cd PadForge.App/bin/Release/net10.0-windows10.0.26100.0/win-x64/publish
zip -r PadForge-vX.Y.Z-win-x64.zip .

6. Create GitHub Release

gh release create vX.Y.Z --title "PadForge vX.Y.Z" --notes "Release notes here"
gh release upload vX.Y.Z PadForge-vX.Y.Z-win-x64.zip

Use --prerelease for beta/RC releases. Use --latest for the default download.

Diagnostic Tools (`tools/`)

Standalone diagnostic utilities and development scripts.

Tool	Command	Framework	Dependencies	Purpose
DsuDiag	`cd tools/DsuDiag && dotnet run`	net8.0	None	Real-time DSU/Cemuhook UDP client for verifying gyro/accel axis mapping
Ds4InputDump	`cd tools/Ds4InputDump && dotnet run`	net8.0-windows	None (raw HID)	Dumps DS4 raw HID input frames. Used to validate Sony Report 0x01 passthrough on PlayStation virtual controllers

The v2 vJoy/Test and vJoy/FfbTest utilities are still in the repo under tools/vJoy/ for historical reference. They target the deprecated vJoy stack and are not part of the v3 toolchain.

Development Scripts

Script	Purpose
`deploy.ps1`	Build + publish + copy to `C:\PadForge`
`deploy_and_restart.ps1`	Deploy + kill running instance + restart
`capture_screenshots.ps1`	Automated wiki screenshot capture
`capture_pads.ps1`	Screenshot the Pads/mapping page
`capture_macros.ps1`	Screenshot the Macros page
`capture_3d_2d.ps1`	Screenshot 3D/2D controller views

A handful of *vjoy* scripts (cleanup_vjoy.ps1, check_vjoy_state.ps1, etc.) are v2 holdovers kept for diagnosing legacy installs the cleanup dialog encounters. The remaining ~50 scripts are ad-hoc UI automation and screenshot utilities.

Troubleshooting Build Issues

Issue	Cause	Fix
`SDL3.dll` not found at runtime	DLL not in `Resources\SDL3\x64\`	Download from SDL3 releases or build from fork
MIDI package not found	`nuget.config` missing or `nuget-local/` folder missing	Ensure both are present at solution root
Missing WPF types	Using `dotnet build` instead of `dotnet publish` for deployment	Always use `dotnet publish -c Release` for deployment
`System.Drawing` ambiguity	WinForms implicit usings conflict with WPF	Ensure `<Using Remove="System.Drawing" />` is in csproj
HelixToolkit errors	Package restore failed	Run `dotnet restore` first
Large exe size (~102 MB)	Expected. Self-contained with bundled .NET runtime	`EnableCompressionInSingleFile` already enabled
CI build fails	.NET 10 SDK not available in runner	Check `actions/setup-dotnet` version supports .NET 10 preview
`HIDMaestro.Core` reference fails to resolve	`Resources/HIDMaestro/HIDMaestro.Core.dll` missing or wrong build	Drop a Release-build `HIDMaestro.Core.dll` from a tagged HIDMaestro release into `Resources/HIDMaestro/`
