I am getting the below error while starting a windows service based on .net framework 5

System.IO.FileLoadException: Could not load file or assembly 'System.Runtime.CompilerServices.Unsafe, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The located assembly's manifest definition does not match the assembly reference. (0x80131040)
    File name: 'System.Runtime.CompilerServices.Unsafe, Version=6.0.0.0

I have tried the below methods. But it is not resolved

Registered the System.Runtime.CompilerServices.Unsafe.dll into GAC
Enabled "Auto-generate binding redirects" on the referenced project files

You should not be registering NuGet assembles into the GAC - that might be the _cause_ of the issue. – Dai Mar 02 '22 at 11:33

Please post the exception's `FusionLog`. – Dai Mar 02 '22 at 11:33
@Dai It was not registered. I tried to check whether it will resolve the issue. But didn't work. – Sandeep M Mar 02 '22 at 11:36
"It was not registered" <-- _that's the point_. We should not be using the GAC for assemblies anymore. – Dai Mar 02 '22 at 11:37
@Dai It wasn't working even without registering – Sandeep M Mar 02 '22 at 11:44
