I use external authentication in my ASP.NET MVC 5 Identity web application. The authentication is implemented using Google account. The registration process goes just fine using Google account, but when I try to log-in (already been registered previously) an exception occurs in this part of code:
var result = await SignInManager.ExternalSignInAsync(loginInfo, isPersistent: false);
The whole code snippet goes just like this:
..though I don't have any "value" properties in 'loginInfo' variable to be undefined!
