[Asp.net core 2 preview 2 ] macOs HttpContext.SignInAsync build error

[AlexTeixeira]

Hello guys,

I look a this issue #1219 to implement my a basic cookie authentication without Identity.

Core version : 2.0.0-preview2-006497
macOs Sierra version : 10.12.5
VS Code : 1.13.1 (1.13.1)
** Omnisharp** : 1.11.0

So basicaly I have the same configuration in startup that show on previous issue

app.UseAuthentication();

 services.AddCookieAuthentication(o =>
            {
                o.CookieName = CLIENT_COOKIE;
                o.LoginPath = new Microsoft.AspNetCore.Http.PathString("/Public/Home");
                //o.LogoutPath = "/api/logout";
                o.ExpireTimeSpan = TimeSpan.FromDays(1);

            });

If I use the new code in my method

await HttpContext.SignInAsync(Startup.CLIENT_COOKIE, new ClaimsPrincipal(identity), props);
I have a build error

error CS1061: 'HttpContext' does not contain a definition for 'SignInAsync' and no extensi
on method 'SignInAsync' accepting a first argument of type 'HttpContext' could be found (are you missing a using directive or an assembly reference?)

If I keep the old method, when I try to sign I go this runtime exception

InvalidOperationException: No authentication handler is configured to handle the scheme: ClientCookie

I'm missing something ?

Namespace? Microsoft.AspNetCore.Authentication
https://github.com/aspnet/HttpAbstractions/blob/b1f92fb6bc42b2cdbb62bd930cedaebafece1e0a/src/Microsoft.AspNetCore.Authentication.Abstractions/AuthenticationHttpContextExtensions.cs#L112

... You change the namespace too.

I did not think to check the namespace and the intellisense do not propose it.

Thanks.
