I feel that I am missing something quite elementary, but I had a firm decision to fix it.
Basically, I am trying to answer this question here: https://stackoverflow.com/a/212618/
It uses the GoogleOAuth2AuthenticationOptions object , which from my Googling should be located here under .net4.5: Microsoft.Owin.Security.Google.GoogleOAuth2AuthenticationOptions
However, my project is MVC -.net 4.5, and it is not! Despite this statement, it should be: 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
So, where on Earth is GoogleOAuth2AuthenticationOptions ? Ha
The solution was as simple as updating Microsoft.Owin.Security.Google on Nuget.
Microsoft.Owin.Security.Google 3.0.0, API Google+ Google. (http://blogs.msdn.com/b/webdev/archive/2014/07/02/changes-to-google-oauth-2-0-and-updates-in-google-middleware-for-3-0-0-rc-release.aspx)
Microsoft.Owin.Security.Google.
Visual Studio : → → NuGet ... Microsoft.Owin.Security.Google Microsoft.Owin.Security.Google, " ", .
"Microsoft.Owin" .
