错误1：

编译正确，运行时 Tests 输出报错，

Failed to load extensions from file 'C:\Users\tangj15\.nuget\packages\xunit.runner.visualstudio\2.5.0\build\net6.0\xunit.runner.visualstudio.dotnetcore.testadapter.dll'. Please use /diag for more information.

错误2：

编译正确，但编译完成时查看Tests输出，提示自动发现test case时错误

Failed to load extensions from file 'C:\Users\tangj15\.nuget\packages\xunit.runner.visualstudio\2.5.0\build\net6.0\xunit.runner.visualstudio.dotnetcore.testadapter.dll'. Please use /diag for more information.

解决办法：

针对错误1，添加如下属性，且设置为true。

    <PropertyGroup>
							

        <CopyLocalLockFileAssemblies>false</CopyLocalLockFileAssemblies>
											

        <GenerateAssemblyInfo>false</GenerateAssemblyInfo>
											

        <GenerateRuntimeConfigurationFiles>false</GenerateRuntimeConfigurationFiles>
											

        <GenerateDocumentationFile>false</GenerateDocumentationFile>
											

        <GenerateDependencyFile>false</GenerateDependencyFile>
											

    </PropertyGroup>
							

针对错误2，添加如下引用。不可缺少（针对xunit）

    <ItemGroup>
							

      <PackageReference Include="coverlet.collector" Version="6.0.0">
																			

        <PrivateAssets>all</PrivateAssets>
											

        <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
											

      </PackageReference>
							

      <PackageReference Include="Microsoft.NET.Test.Sdk" Version="17.6.3" />
																			

      <PackageReference Include="Microsoft.TestPlatform" Version="17.6.3" />
																			

      <PackageReference Include="xunit" Version="2.5.0" />
																			

      <PackageReference Include="xunit.runner.visualstudio" Version="2.5.0">
																			

        <PrivateAssets>all</PrivateAssets>
											

        <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
											

      </PackageReference>
							

    </ItemGroup>
