I'm using User.FindFirstValue(ClaimTypes.NameIdentifier) to retrieve the user Id of the current logged in user. The resulting seems to be a random string.
If I look up a user in Azure AD the ID there looks like a guid. And if lookup a user in the Graph Api the Id is also a Guid. Is there some way to relate the two properties?
Or is the .net core current user not related to the logged in Azure Ad user?
