PostSharp won't build in latest Visual Studio (16.8.1)

Since upgrading to the latest Visual Studio (16.8.1), I can no longer compile any projects that use PostSharp.

I receive the following build errors (for PostSharp v6.7.11 AND for 6.8.1-preview):

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'. The system cannot find the file specified. See below for details.

Note that I have NOT converted any projects to .NET 5.0. I just updated Visual Studio to the latest version.

Does anyone know how to resolve this? Thanks

Change the SDK used to build your project by adding a new file in the same directory as your .sln file called global.json:

{
  "sdk": {
    "version": "3.1.404",
    "rollForward": "latestPatch"
  }
}

Install the latest version of the .Net core SDK here: https://dotnet.microsoft.com/download/dotnet-core/3.1

Postsharp 6.7 does not support .Net 5 SDK.

See this article from PostSharp for more information: https://blog.postsharp.net/post/updating-to-vs-168-breaks-build.html

This was resolved by cleaning the solution before building. Yes, I should have tried this immediately, but in a solution of ~70 projects, this PostSharp error was the only new build error.
