ASP.NET Core No authentication handler is configured to handle the scheme Cookies

ASP.NET Core
This post is about ASP.NET Core authentication, which throws an InvalidOperationException - No authentication handler is configured to handle the scheme Cookies. In ASP.NET Core 1.x version, the runtime will throw this exception when you are running ASP.NET Cookie authentication. This can be fixed by setting options.AutomaticChallenge = true
in the Configure method.
Here is the full code.
And here is the SignIn method.
Recently I upgraded on of ASP.NET Core 1.x solution to ASP.NET Core 2.0. In ASP.NET Core 2.0, ASP.NET Core team changed the authentication methods and now there is nothing like UseCookieAuthentication
. I got some compilation issues with the existing solution. Since most of the documentation it only talking about ASP.NET 1.x, I had to spent time, and I fixed it.
Here is the new Startup.cs code for authentication.
And in the configure method, you need to use app.UseAuthentication();
method.
But when I am running, I got the same exception.
After spending sometime, I figured out the issue. You don’t need to call the HttpContext.Authentication.SignInAsync
method. Instead you need to call the HttpContext.SignInAsync
method for authentication.
Here is the updated Signin code.
Happy Programming :)
