Question

I developed a web system using ASP.NET MVC 4 and I must perform an integration using .NET Web API and Windows Forms Application.

So far everything has been fine, but now I need to authenticate the users using Windows Forms Application and this application will be open on the internet.

My application already contains users that are registered in the database and currently are authenticated using the component ‘Authorize’ of ASP.NET MVC.

For data consumption through the client (Windows Forms Application) currently I use the library Microsoft ASP.NET Web Client API.

How can I accomplish this task safely?
Does anyone have any suggestions?

You can extend the HttpClient to add authentication. One example can be found here. It shows how to add a HttpMessageHandler into your pipeline for authentication using OAuth.
