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. For debugging, I added NuGet System.Security.Cryptography.Pkcs package but that does not fix the problem.
Any troubleshooting ideas?
The stack shows that MiniProfilerMiddleware.cs is throwing the exception:
InvalidOperationException: Cannot find compilation library location for package 'System.Security.Cryptography.Pkcs'

The fix: Add the following configuration setting to your .csproj file.
<GenerateRuntimeConfigDevFile>true</GenerateRuntimeConfigDevFile>
It seems that this issue is most likely related to a breaking change with .NET 6.0 which was not documented. It worked for me, without adding/removing any of the above mentioned libraries.
