多实例问题-到.NET5的.NET框架4.8WPF应用程序

Question

当我尝试将我的WPF应用程序转换到.NET 5时，我得到了以下信息。

有谁能给我引路吗？

C:\WINDOWS\system32>try-convert -p "D:\ClientNew\Routines\Routines.csproj"
Multiple installs of MSBuild detected please select one:
Instance 1
    Name: .NET Core SDK
    Version: 5.0.302
    MSBuild Path: C:\Program Files\dotnet\sdk\5.0.302\
Instance 2
    Name: .NET Core SDK
    Version: 2.1.524
    MSBuild Path: C:\Program Files\dotnet\sdk\2.1.524\
Instance 3
    Name: .NET Core SDK
    Version: 2.1.202
    MSBuild Path: C:\Program Files\dotnet\sdk\2.1.202\

我也关注了Multiple installs of MSBuild，但没有太多帮助。

我还安装了upgrade-assistant，现在尝试使用这个命令。我收到Required command was not provided错误：

C:\Users\rya\Test>upgrade-assistant C:\Users\rya\Test\Client\Screen.sln
Required command was not provided.
Unrecognized command or argument 'C:\Users\rya\Test\Client\Screen.sln'

这似乎是因为转换工具想知道要使用哪个版本的MSBuild。

这个问题：Dotnet project conversion try-convert fails when "Multiple installs of MSBuild"有一些关于如何指示工具应该使用哪个版本的信息，尽管到目前为止它还没有一个公认的答案。
