IdentityServer4 dotnet7 produce exception

Question

when using Automaper 10.1.1, with identityserver4 and .net 7, identityserver4 is the last free version of IdentityServer and doesn't work with a higher version of AutoMapper where this issue is resolved in this link: Issue. Automapper 10 + identity server 4 + dotnet 7 simply when I hit /.well-known/openid-configuration I got this exception

I tryed all Higher versions and I get another exception because identity server 4 requires AutoMapper version>=10 and <11, in this case I got this exception:

System.MissingMethodException: Method not found: '!2 AutoMapper.IMappingExpressionBase`3.ConstructUsing(System.Linq.Expressions.Expression`1<System.Func`2<!0,!1>>)'.
   at IdentityServer4.EntityFramework.Mappers.ClientMapperProfile..ctor()

Answer 1

I also got this exception "The type initializer for 'IdentityServer4.EntityFramework.Mappers..." using .NET 8

Installing the latest version of the following packages fixed this issue for me:

• Cnblogs.IdentityServer4.EntityFramework.Storage
• AutoMapper
