由于升级到最新的Visual Studio(16.8.1(，我无法再编译任何使用PostSharp的项目。
我收到以下构建错误(适用于PostSharp v6.7.11和6.8.1-审查(：
1>POSTSHARP : error : error: Unhandled exception (PostSharp.Compiler.Hosting.CommandLine.dll 6.8.1 release | .NET Core 5.0.0 (X64)): Could not load file or assembly 'NuGet.Versioning, Version=5.8.0.6823, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.

请注意，我没有将任何项目转换为.NET 5.0。我刚刚将Visual Studio更新到最新版本。
有人知道如何解决这个问题吗？感谢
这是通过在构建前清洁解决方案解决的。是的，我本应该立即尝试，但在大约70个项目的解决方案中，这个PostSharp错误是唯一的新构建错误。
通过在与.sln文件相同的目录中添加一个名为global.json:的新文件来更改用于构建项目的SDK
{
"sdk": {
"version": "3.1.404",
"rollForward": "latestPatch"
}
}
在此处安装最新版本的.Net核心SDK：https://dotnet.microsoft.com/download/dotnet-core/3.1
Postsharp 6.7不支持.Net 5 SDK。
