DllNotFoundException thrown with Preview 5 [Bug]

[AlexLablaiksSAP]

Description

Running a new .NET MAUI App project (dotnet new maui -n MauiFive) created in Visual Studio 2019 Preview 2 with Maui Preview 5 throws a System.DllNotFoundException with a message of "Unable to load DLL 'Microsoft.Graphics.Canvas.Text.dll' or one of its dependencies: The specified module could not be found." I will attach the call stack (CallStack.txt).

Additionally, I am observing warning icons over the SDK portion of the WinUI Dependencies in the Solution Explorer (see screenshot).

Steps to Reproduce

1. Update to Visual Studio 2019 Preview 2
2. Install Microsoft .NET SDK 6.0.100-preview.5.21302.13 (x64)
3. Perform dotnet new maui -n MauiFive
4. Open the MauiFive.sln, Build and Run
5. System.DllNotFoundException Exception is thrown with "Unable to load DLL 'Microsoft.Graphics.Canvas.Text.dll' or one of its dependencies: The specified module could not be found."

Expected Behavior

No exception is thrown and the screen renders correctly.

Actual Behavior

Aforementioned exception is thrown and the screen is a blank purple one which will correctly render when resized as indicated in #1362

Basic Information

• Version with issue: Visual Studio 2019 Preview 2 w/ .NET SDK 6 Preview 5
• Last known good version: Visual Studio 2019 Preview 1 w/ .NET SDK 6 Preview 4

• Affected Devices:

Screenshots

Uncertain if related, but here is the screenshot of the warning icons in Solution Explorer:

Workaround

Ignore the exception, allow the blank screen to render and then resize the window, similar to #1362.

I'd like to add that there was a WinUI (package) project which was used to run Blazor (not like it really did for me). Now with updated template it is missing. In my case program simple fails with COMException (0x80040154) - (0x80040154 (REGDB_E_CLASSNOTREG)).
In my case there is no workaround as application simply crashes.

When running project from VisualStudio I get:
The project doesn't know how to run the profile MyBlazorApp.BlazorClient.Maui.WinUI.

@Fabi Thank you.

Please make sure you follow the latest steps here to install all the requirements: https://github.com/dotnet/maui/wiki/Getting-Started

Most requirements are installed by the maui-check tool, but there are a few VSIX tools you have to install individually for WinUI support.
