[Problem/Bug]: Missing ARM condition in WebView2 NuGet

[mattleibow]

What happened?

When building with .NET MAUI, we notice that ARM machines are failing to show the webview. I notice that there is an incorrect x86 WebView2Loader.dll in the output dir instead of arm64.

Looking at the targets (build\Common.targets), I see:

<EffectivePlatform Condition="'$(NETCoreSdkRuntimeIdentifier)' == 'win-x86'">x86</EffectivePlatform>
<EffectivePlatform Condition="'$(NETCoreSdkRuntimeIdentifier)' == 'win-x64'">x64</EffectivePlatform>

For ARM64, there should be an additional:

<EffectivePlatform Condition="'$(NETCoreSdkRuntimeIdentifier)' == 'win-arm64'">arm64</EffectivePlatform>

I tested with adding that myself and things work again.

Windows App SDK 1.7 Preview 1 release will contain an updated WebView2 package reference (v1.0.2903.40) with a fix for this issue. A workaround is to add an explicit reference to a recent WebView2 package.
