Use child of CognitoUser for Identity

[fracampit]

I am trying to move from the MSSQL EntityFramework Identity Provider to AWS Cognito via this project.

I am currently using a custom application user class that inherits from Microsoft's IdentityUser. I use this class to give a few more properties to the user (Name, Surname, Profile Image). All the scaffolded Identity pages are using the custom class.

I was hoping I could simply switch the parent class for my custom user class from IdentityUser to CognitoUser and be done. However, when I try to use UserManager<ApplicationUser> in any class, DI throws an error saying it cannot find that service.

Services.AddDefaultIdentity<ApplicationUser>() injects UserManager<ApplicationUser>, so I was expecting that Services.AddCognitoIdentity() would inject UserManager<CognitoUser>, which would match UserManager<ApplicationUser> since ApplicationUser is a child of CognitoUser, but its not the case.

Is there a way to use a custom application user class like when you are using the MSSQL EntityFramework Identity Provider?

Just for reference, the class CognitoUserManager restricts the underlying type to CognitoUser via clause UserManager where TUser : CognitoUser.

@fracampit Thanks for posting guidance question. Could you please share the following:

• Sample code to reproduce the issue.
• Stack trace of the error and exact error message.

Just a gist, ServiceCollection.AddCognitoIdentity() just maps the type CognitoUser when injecting Cognito user and calling services.AddIdentity<CognitoUser, CognitoRole>().
