Exception on startup with version 8.3.0

[LeDahu22]

Describe the bug

Hi,

After upgrading from 8.2.2 to 8.3.0, as soon I run my WPF application, I've got the following exception :

System.TypeInitializationException : 'The type initializer for 'Module' threw an exception.'
FileNotFoundException : Could not load file or assembly 'WinRT.Runtime, Version=2.1.0.0, Culture=neutral, PublicKeyToken=99ea127f02d97709'. Specified file not found.

It crashes on the very first line of OnStartup method :

IHost host = CreateHostBuilder().Build();

There seems to be something wrong related to WinRT.Runtime.

Thanks

This is unfortunate, but I think it's expected so far until the new .NET SDK comes out. The problem is that the MVVM Toolkit is using the new Windows SDK projections, but your app is trying to use the old ones (because you have an old version of the .NET SDK that doesn't know about this new version yet). As a workaround, can you try adding this to your .csproj file:

<WindowsSdkPackageVersion>10.0.22621.41</WindowsSdkPackageVersion>

Replace 22621 with whatever Windows SDK you're using as target (it should match your TargetFramework). For instance:

<TargetFramework>net8.0-windows10.0.18362.0</TargetFramework>
<WindowsSdkPackageVersion>10.0.18362.41</WindowsSdkPackageVersion>

Let me know if this solves the issue for you! 🙂

I also encountered this problem.

@Sergio0694 Thank you for your quick answer, I changed my csproj to what you advised and the issue went away

<TargetFramework>net8.0-windows10.0.18362.0</TargetFramework> <WindowsSdkPackageVersion>10.0.18362.41</WindowsSdkPackageVersion>

Thanks a lot ! 😃

• In my csproj there is no line <WindowsSdkPackageVersion>10.0.18362.41</WindowsSdkPackageVersion>
• If I try to paste it in, when building it says:
  Severity Code Description Project File Line Suppression State Details
  Error (active) NU1102 Unable to find package Microsoft.Windows.SDK.NET.Ref with version (= 10.0.26100)
• Found 263 version(s) in nuget.org [ Nearest version: 10.0.26100.1 ]

Like I said, you need to use a package version that matches your target framework SDK version.

So for instance, if you have:

<TargetFramework>net8.0-windows10.0.26100.0</TargetFramework>

Then you need:

<WindowsSdkPackageVersion>10.0.26100.41</WindowsSdkPackageVersion>

Etc., basically just replace the last .0 with .41 from the target framework.
