In this post, I will describe how to port a desktop application from .NET Framework to .NET Core. I picked a WinForms application as an example. Steps for WPF application are similar and I’ll describe what needs to be done different for WPF as we go. I will also show how you can keep using the WinForms designer in Visual Studio even though it is under development and is not yet available for .NET Core projects. 

You already know how role-based authorization works in ASP.NET Core.

[Authorize(Roles = "Administrator")]
public class AdministrationController : Controller
{
}

But what if you don't want hardcode roles on the Authorize attribute or create roles later and specify in which controller and action it has access without touching source code?

DynamicAuthorization helps you authorize users without hardcoding role(s) on the Authorize attribute with minimum effort. DynamicAuthorization is built at the top of ASP.NET Core Identity and use identity mechanism for managing roles and authorizing users.
