How to use Roles in ASP.NET Core 2.1?

Question

I\'ve created a test project using:

dotnet new razor --auth Individual --output Test

This creates a Startup.cs that contains:

p         


        

Answer 1

In addition to the answers already provided, despite adding .AddRoles(), I still could not get Authorization when use Authorize(Roles = "Administrator") on my controllers. For some reason,the "role claim doesn't seem to affect IsUserInRole or AuthorizeAttribute with a role name."

To make use of roles I would suggest that one use the ASP.NET 2.0 way like below:

services.AddIdentity()
            .AddDefaultUI()
            .AddDefaultTokenProviders()
            .AddEntityFrameworkStores();

This way, you get to use your roles and also get the Identity pages scaffolded for you.
