How are Authentication type names registered in asp.net vnext
asp.net, asp.net-core, asp.net-identity, asp.net-mvc, c#
Solution
Turns out I had setup MVC before the CookieAuthentication so the AuthenticationType was not registered in MVC when it tried to authenticate the user. As MVC depends upon the authentication I just had to bump it up and register it before MVC.
Problem
So I am updating an Open Source asp.net Identity provider for MongoDB to work with Asp.Net Identity 3.0 (aka vnext). So far I have been able to register the provider and create users but when using the SignInManager if a correct UserName/Pass is provided I get the error InvalidOperationException: The following authentication types were not accepted: Microsoft.AspNet.Identity.Application I have tracked down the error to here https://github.com/aspnet/HttpAbstractions/blob/dev/src/Microsoft.AspNet.PipelineCore/DefaultHttpResponse.cs but I can't seem to see where the SignInContext.Accepted name is getting added to the SignInContext. I am using the Alpha-2 versions of all of the vnext libraries that are being used in VS14 CTP2 Below is my Startup.cs ``` public void Configure(IBuilder app) { try { // For more information on how to configure your application, visit http://go.microsoft.com/fwlink/?LinkID=398940 var configuration = new Configuration(); configuration.AddJsonFile("config.json"); configuration.AddEnvironmentVariables(); // app.UseLogRequests("try"); app.UseErrorPage(ErrorPageOptions.ShowAll); app.UseServices(services => { services.AddIdentity<MyUser>() .AddMongoDB<MyUser>(configuration.Get("Data:MongoIdentity:ConnectionString"), configuration.Get("Data:MongoIdentity:DBName")) .AddHttpSignIn<MyUser>(); // Add MVC services to the services container services.AddMvc(); }); // Add static files to the request pipeline app.UseStaticFiles(); app.UseMvc(routes => { routes.MapRoute( name: "default", template: "{controller}/{action}/{id?}", defaults: new { controller = "Home", action = "Index" }); routes.MapRoute( name: "api", template: "api/{controller}/{action}", defaults: new { action = "Index" }); }); // Add cookie-based authentication to the request pipeline app.UseCookieAuthentication(new CookieAuthenticationOptions { AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie, LoginPath = new PathString("/Account/Login"), }); } catch (Exception ex) { Console.Write(ex.ToString()); throw; } } ```
