[Problem/Bug]: [NET 9] Dependency conflict

[hi-xiaoxin]

What happened?

This phenomenon occurred after we upgraded to .NET 9.0, and a warning is generated during compilation:

File: Microsoft.Common.CurrentVersion.targets

发现无法解析的“WindowsBase”的不同版本之间存在冲突。
“WindowsBase, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35”与“WindowsBase, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35”之间存在冲突。
    已选择“WindowsBase, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35”，因为它是主版本而“WindowsBase, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35”不是。
    依赖于“WindowsBase, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35”[C:\Program Files\dotnet\packs\Microsoft.NETCore.App.Ref\9.0.0\ref\net9.0\WindowsBase.dll]的引用。
        C:\Program Files\dotnet\packs\Microsoft.NETCore.App.Ref\9.0.0\ref\net9.0\WindowsBase.dll
          导致引用“C:\Program Files\dotnet\packs\Microsoft.NETCore.App.Ref\9.0.0\ref\net9.0\WindowsBase.dll”的项目文件项 Include 特性。
            C:\Program Files\dotnet\packs\Microsoft.NETCore.App.Ref\9.0.0\ref/net9.0/WindowsBase.dll
    依赖于或已统一到“WindowsBase, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35”[] 的引用。

          导致引用“C:\Users\user1\.nuget\packages\microsoft.web.webview2\1.0.2895-prerelease\lib_manual\net5.0-windows10.0.17763.0\Microsoft.Web.WebView2.Wpf.dll”的项目文件项 Include 特性。

The project does not use WPF or WinForms; it controls windows through the Win32 API (Set Handle). Therefore, there is actually no dependency on WindowBase at all. Previously, everything was normal in the .NET 8.0 environment.

Although the project is still running normally, we would also like to find the cause and eliminate this warning.

Thanks

Importance

Moderate. My app's user experience is affected, but still usable.

The warning also occurs under .NET 8 and only since WebView2 version 1.0.2849.39. The message does not occur in WebView2 version 1.0.2792.45.
