Get current (logged) user in ASP.NET Core 3.0 .razor page

Question

I\'m testing the waters with a blazer server-side app and trying to get the logged user in a .razor page. This

UserManager.GetUserAsync(User)

Answer 1

What I did:

1. added this to Startup.ConfigureServices

services.AddHttpContextAccessor();

2. used this to get the username in my .razor page, these 2 lines first

@inject UserManager UserManager
@inject IHttpContextAccessor HttpContextAccessor

3. then the call to show the username like this:

Hello @UserManager.GetUserName(HttpContextAccessor.HttpContext.User)
