I use IdentityServer4 for auth which gets installed with Asp.net core web project in visual studio 2019. After upgrading to asp.net 3.1, I get below error on SignOut. I tried force update all the Nugets to latest. Still, I couldn't make it work. Appreciate any workaround.
TypeLoadException: Could not load type 'Microsoft.AspNetCore.Http.IReadableStringCollectionExtensions' from assembly 'IdentityServer4, Version=3.1.0.0, Culture=neutral, PublicKeyToken=f294d0afe402bb2b'.

I fixed this by reverting the IdentityServer4.EntityFramework reference from version 3.1.0 to 3.0.2, it would seem that the missing type is not yet implemented in 3.1.0.
I spent a few days researching this for work and I was unable to find any official documentation with regards to the problem or to the missing type. So the solution came from exasperation more than anything else. I apologize that I cannot provide you with adequate reasoning as to why it needs to be reverted, just that by doing it I fixed it.
