I want to know if its possible and how to do the following , i have a basic MVC application (ASP.Net) that i have modified to work for me. Now the application already handles authentication perfectly fine but i need to use this authentication in another app.
Without creating a webservice is it possible for me to make calls to the applications authcontroller , if so how
You can’t directly call a controller in another application because it is in a separate AppDomain. If you just want to reuse the existing code, you could refactor it into a separate assembly (library project), include that assembly in your new application, and just reference it from your logon controller. If you are trying to do single-sign on, then you may want to look at existing SSO solutions, such as JA-SIG CAS 2.0.
