title: How does the "ASP.Net Identity" compare with "Windows Identity Foundation"?
body: <p>I found this nice article that shows the evolution of the ASP.Net identity frameworks:
  <a href="http://www.asp.net/identity/overview/getting-started/introduction-to-aspnet-identity">http://www.asp.net/identity/overview/getting-started/introduction-to-aspnet-identity</a></p>
  
  <p>However, I'm interested in how the Windows Identity Framework (WIF) fits into the picture with the new ASP.Net Identity Framework.  Are they yet another set of competing Microsoft implementations?</p>
  
  <p>Furthermore, if a developer is interested in supporting SAML authentication (which WIF supports), Active Directory authentication, and Forms Authentication, which would you choose?</p>
