Converting Aspnet to aspnetcore: RequestContext.Principal

Question

Ok, so I'm working on converting a webApi from aspnet to aspnetcore.

I have the following inside of an HTTP post.

var name = ControllerContext.RequestContext.Principal.Identity.Name;
widget.CreatedBy = name;
//Other properties
DataContext.Widgets.Add(entity);

The problem I'm running into is that RequestContext doesn't seem to exist in aspnetcore. I've been searching for the better part of a day for an equivalence.

In ASP.NET Core, from within a controller this is done like:

var claimsPrincipal = User;

Reference: Migrate from ClaimsPrincipal.Current

So far Im getting null for name this way, but i think its the right track.

For the User.Name property to be set, ClaimType used for the user name claim must match what your auth is setting it to: learn.microsoft.com/en-us/dotnet/api/…

I suppose this answer is correct. I can plainly see the info i want on user.claims[9]. But im not having any luck updating the claimtype for name. Ive tried numerous sites and sources and just gone down rabbit holes with no results.I suppose i'll just do a query on claims for "schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier" but that seems ugly.

@Seth You can just do var name = User.FindFirstValue(ClaimTypes.Name);
