Answer 1

Kentor.AuthServices is an open source service provider for .NET that is designed to be as simple as possible to use in ASP.NET applications.

There are three nuget packages available

• Kentor.AuthServices core library and an Http Module for web forms applications.
• Kentor.AuthServices.Mvc MVC controller for simple setup for MVC applications.
• Kentor.AuthServices.Owin Owin middleware for modern MVC applications and integration with ASP.NET Identity.

Disclaimer: I'm the author of Kentor.AuthServices, but as it's free, I make no money from people using it.

With ASP.NET, you would normally use WIF but WIF doesn't support the SAML protocol.

Two ways of doing this.

Use ADFS as a bridge so:

App. --> WIF --> ADFS --> SAML --> IDP

Use a .NET 3rd party stack in your app.
