Step by steplink

1. Create new application with .NET server-side project, add new MSSQL data-source connected to Northwind database, auto-generate pages and enable security.

2. To get the name of the authenticated user you can do the following:

var userName = this.HttpContext.User.FindFirst(ClaimTypes.Name).Value;

Dim userName = Me.HttpContext.User.FindFirst(ClaimTypes.Name).Value

For .NET Core 2.x you need to decorate your class with [Authorize] attribute in order to access current authenticated user:

using System.Security.Claims;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Identity;

namespace [ApplicationName].Controllers.[DataSourceName]
{
    [Authorize(AuthenticationSchemes="Bearer")]
    public partial class OrdersController
    {
    }
}

Imports System.Security.Claims
Imports System.Threading.Tasks
Imports Microsoft.AspNetCore.Authorization
Imports Microsoft.AspNetCore.Identity

Namespace [ApplicationName].Controllers.[DataSourceName]
    <Authorize(AuthenticationSchemes:="Bearer")>
    Public Partial Class OrdersController
    End Class
End Namespace

3. To authorize only certain roles to have access to controllers you can use again the Authorize attribute:

using System.Security.Claims;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Identity;

namespace [ApplicationName].Controllers.[DataSourceName]
{
    [Authorize(Roles="Administrator", AuthenticationSchemes="Bearer")]
    public partial class OrdersController
    {
    }
}

Imports System.Security.Claims
Imports System.Threading.Tasks
Imports Microsoft.AspNetCore.Authorization
Imports Microsoft.AspNetCore.Identity

Namespace [ApplicationName].Controllers.[DataSourceName]
    <Authorize(Roles:="Administrator", AuthenticationSchemes:="Bearer")>
    Public Partial Class OrdersController
    End Class
End Namespace

4. Run the application, login and check current user.
