.NET 8 Issue. Method 'get_ServerSideSessions' in type 'Microsoft.AspNetCore.ApiAuthorization.IdentityServer.ApiAuthorizationDbContext`1' from assembly 'Microsoft.AspNetCore.ApiAuthorization.IdentityServer, Version=7.0.20.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' does not have an implementation.

Describe the bug

Unable to load the application upgrading Duende.IdentityServer to 7.0 with Microsoft.AspNetCore.ApiAuthorization.IdentityServer 7.0.20 in .NET 8.

This is still an issue for me. I tried the workaround mention on the other closed tickets related to this issue but no luck.

Microsoft.AspNetCore.ApiAuthorization.IdentityServer is still in 7, will there be a fix when the version 8 comes out? And when are we expecting that?

Expected Behavior

Application should build and load with the latest Microsoft.AspNetCore.ApiAuthorization.IdentityServer 7.0.20 and be compatible with Duende.IdentityServer to 7.0 using .NET 8.

Steps To Reproduce

Create a .NET Core 8 application that has Microsoft.AspNetCore.ApiAuthorization.IdentityServer 7.0.20. Duende.IdentityServer 6.0.4 will get installed as its dependencies.

Manually upgrade the Duende.IdentityServer to 7.0.

On Build/Run, application is not loading and returning the error message above.

Exceptions (if any)

need to upgrade the package to this version:

they are still on preview on this, I dont know why. I this was discontinued due to thirdy party license of identity server.
