Can't load Microsoft.Toolkit.Uwp.Notifications in preview 2 (FileNotFoundException)

[mtissington]

Have been running preview-1 without any issues, upgraded to preview-2 and now when I build a release version and ship we get the following exception.

System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Toolkit.Uwp.Notifications, Version=7.0.0.0, Culture=neutral, PublicKeyToken=4aff67a105548ee2' or one of its dependencies.

@mtissington What's the App min and Target Version are you using?

[mtissington]

<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.7.2" />

你好，请问.NET Core3.1支持吗？怎么最新版本没有WebViewCompatible这个对象了

[michael-hawker]

@duzhenyi see info about WebView here. Everything has moved to WebView2 which you can find out about here.

@mtissington is this a C# or C++ project, can you provide a bit more details on your configuration?

The PR you mentioned would have occurred with 6.1.0, so if that's working for you it may be something different like the PR we did #3423 here for 6.1.1. Can you try either of those two versions and let us know if they both work or not?

@azchohfi did we pull the 6.1.1 fix from @andrewleader into the main branch?

[mtissington]

It as c# project - and I include the config file contents.

7.0.0-preview2 causes the provided exception, if we revert to 7.0.0-preview1 everything works correctly.

[azchohfi]

@michael-hawker yes. The PR was merged on master, and cherry-picked to a branch of rel/6.1.0, just for 6.1.1.

[michael-hawker]

@mtissington have you validated the latest v7.0.0-preview5 are these issues resolved?

FYI @andrewleader

[mtissington]

Initial testing shows v7.0.0-preview5 is still broken ... still testing to see if I can provide any more information.
