title: Where do you find GoogleOAuth2AuthenticationOptions?
body: <p>I feel like I am missing something pretty basic however I have had a solid effort at resolving it.</p>
  
  <p>Basically I am trying to follow this question's answer here: <a href="https://stackoverflow.com/a/22694372/768952">https://stackoverflow.com/a/22694372/768952</a></p>
  
  <p>It makes use of a <strong>GoogleOAuth2AuthenticationOptions</strong> object, which from my Googling should be located here within the .net4.5 framework:  <strong>Microsoft.Owin.Security.Google.GoogleOAuth2AuthenticationOptions</strong> </p>
  
  <p>However my MVC project is .net 4.5 and it's not there! Despite this saying it should be: <a href="http://www.symbolsource.org/Public/Metadata/NuGet/Project/Microsoft.Owin.Security.Google/2.1.0-rc1/Release/.NETFramework,Version%3Dv4.5/Microsoft.Owin.Security.Google/Microsoft.Owin.Security.Google/GoogleOAuth2AuthenticationHandler.cs?ImageName=Microsoft.Owin.Security.Google" rel="nofollow noreferrer">http://www.symbolsource.org/Public/Metadata/NuGet/Project/Microsoft.Owin.Security.Google/2.1.0-rc1/Release/.NETFramework,Version%3Dv4.5/Microsoft.Owin.Security.Google/Microsoft.Owin.Security.Google/GoogleOAuth2AuthenticationHandler.cs?ImageName=Microsoft.Owin.Security.Google</a></p>
  
  <p>So where on earth is <strong>GoogleOAuth2AuthenticationOptions</strong>? haha</p>
