Unable to Find GoogleOAuth2AuthenticationOptions – MVC4/5

Hey everyone,

I was following the guide provided via the startup.auth.cs link on how to add Google authentication to your app. The problem I hit was that the example types used weren’t available, specifically GoogleOAuth2AuthenticationOptions.

Thankfully the fix fix for this was pretty easy, simply update OWIN via NuGet:

– Right click on your project
– Go to Manage NuGet Packages
– Click on the updates drop down
– Search for OWIN
– Update all of the relevant options

Thanks to this Stackoverflow post for the solution: http://stackoverflow.com/a/23606431/522859
