InvalidOperationException: Cannot find compilation library location for package 'System.Security.Cryptography.Pkcs'

Just upgraded a web project to .NET 6.0. Project compiles but when I run the site I get the following error:

InvalidOperationException: Cannot find compilation library location for package ‘System.Security.Cryptography’.

I am using MiniProfiler.AspNetCore.Mvc 4.2.2.

From stack below it is pointing to https://github.com/MiniProfiler/dotnet/blob/a48fc7a9de95f0bbf583c3094d55b36096484493/src/MiniProfiler.AspNetCore/MiniProfilerMiddleware.cs#L103

Thanks both! I’m not sure what the cause is here but the issue above is absolutely the way to go - I’ve poked who I know to look at this and get traction there. I’ll close this out and subscribe to the aspnetcore issue as well - I’m curious what this is 😃

@NickCraver - Thanks for the inputs, and you are completely right - removing MiniProfiler did not solve the problem. Also adding https://www.nuget.org/packages/System.Security.Cryptography.Pkcs/ did not solve the problem either.

What fixed the problem is exactly this:

package/DLL potentially isn’t getting yanked into your bin

I copied System.Security.Cryptography.Pkcs.dll manually to the bin and it works, so thanks. I will try and figure out why the dll is not dropped in the bin
