问题 Creating a new user, fetching the user again with usermanager for testing, and then using the method AddLoginAsync with the recently fetched user gives the error ConcurrencyFailure, Optimistic concurrency failure, object has been modified. When fetching the user the "ConcurrencyStamp" has the correct etag, but after the "AddLoginAsync" I can see the user object has an invalid etag, the ConcurrencyStamp is a GUID. I have followed the documentation and added this to the IdentityUser model

问题 I am trying to build a structure using repository pattern in entity framework core. I have an generic interface and a service for general operations. They simply do CRUD transactions.

问题 I'm still learning the Identity Framework and am pretty lost in trying to setup authentication in my .Net Core 2 MVC application. Any suggestions are appreciated since I'm not even sure what I'm doing is correct. I have a requirement to integrate an OpenID Connect identity provider for authentication and use a secondary data source for authorization . Inconveniently I cannot use any claim from the OIDC IdP except for the name claim. The rest of the user claims must come from the secondary

问题 I have an application which requires role authorization using custom database. The database is set up with a tblUsers table that has a reference to a tblRoles table. The users are also already assigned to their roles. I also want to use the [Authorize(Role = "RoleName")] attribute on each action to check if an authenticated user is assigned to "RoleName" in the database. I'm having a lot of trouble figuring out where I need to make a modification to the [Authorize] attribute so it behaves
