Update the 2.1 authentication examples -> at Startup.cs .AddDefaultUI() method is missing

[hubekpeter]

Since 2.1 the identity views have been moved under the separate area. The examples would not work without .AddDefaultUI() method been called.

services.AddIdentity<IdentityUser, IdentityRole>()
.AddEntityFrameworkStores()
.AddDefaultTokenProviders()
.AddDefaultUI();

Thanks

I was just taking a look at the issues, and there are several that pertain to updating Identity for 2.1. Those issues should cover this one. The work is going on now, and I doubt it will take long to get the topics updated.

Sample updates are tracked by #5495.

Did run into the same issue when using a customized Identity. If services.AddDefaultIdentity is used there is no issue with the separate area, but as soon as services.AddIdentity is used, AddDefaultUI needs to be added to get correct routing. Otherwise (it not authorized, for example) it routs to /Account/Login and not to /Identity/Account/Login. My two cents.
