What happened?

I am getting MSBuild Errors when compiling project using cmd through MSBuild, not from VS 2022(in VS 2022, it is building successfully)

  • getting MSBuild issues for one of my .csproj file when Webview2 version is greater than 1.0.2739.15

I'm seeing this too. The 'Microsoft.Web.WebView2.0.9.579-prerelease' version used in the WebView2 Samples build fine but not 'Microsoft.Web.WebView2.1.0.3537.50' that nuget delivers.

Same issue here: Trying to build .NET 4.8 project with WebView2 1.0.3505.46 using MSBuild. Getting the same error: The attribute "Implementation" in element <WindowsMetadataReference> is unrecognized.
