Hello guys,

I have a web API that was working without a problem. But today I am getting this error on the production server:

Could not load file or assembly 'System.Runtime.CompilerServices.Unsafe, Version=4.0.4.1, Culture=neutral,
PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The located assembly's manifest definition does not
match the assembly reference. (Exception from HRESULT: 0x80131040)

There is no such problem with the local machine. I tried to update this System.Runtime.CompilerServices.Unsafe but still having the same problem. Any ideas on how to fix it?

Best Regards.
