I'm attempting to integrate AspNetCore.Identity.MongoDbCore into my application. However, upon running the application, I encounter the following error:

System.MissingMethodException: 'Method not found: 'Void MongoDB.Bson.BsonDefaults.set_GuidRepresentationMode(MongoDB.Bson.GuidRepresentationMode)'.'

Here is the relevant portion of my code:

builder.Services.AddIdentityCore<ApplicationUser>()
        .AddRoles<MongoIdentityRole>()
        .AddMongoDbStores<ApplicationUser, MongoIdentityRole, Guid>(connectionUri, "databasename")
        .AddSignInManager()
        .AddDefaultTokenProviders();

Could anyone advise on how to resolve this issue or what might be causing it?

.net8/AspNetCore.Identity.MongoDbCore 6.0/MongoDbDriver 3.3.0

    Maybe I go into the wrong direction, but when I add your codes and nuget packages into my .Net 8 mvc project, I didn't get your error. I deduce the error is coming from a version-mismatch issue. May I know whether it helped or not when using lower version of MongoDbDriver, such as 2.28.0? Commented Apr 8 at 2:19
