The remote server returned an error: (400) Bad Request Microsoft.AspNet.Membership.OpenAuth

问题

I'm using Microsoft.AspNet.Membership.OpenAuth when I create a new asp.net webform .net 4.0 and I config AuthConfig.cs:

OpenAuth.AuthenticationClients.AddFacebook(
                appId: "my appId",
                appSecret: "my appSecret");

In Facebook app config: Website with Facebook Login: http://www.tindep.com

But when I login with facebook it's error:

Server Error in '/' Application.
The remote server returned an error: (400) Bad Request.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Although Google, Twitter, msdn login successful (Check tindep.com/Account/Login.aspx) It's only error at hosting (tindep.com/Account/Login.aspx). localhost:57846/Account/Login.aspx login facebook success.

Please, help me find cause.

Thanks alot of!

There was a defect open related to this: https://github.com/DotNetOpenAuth/DotNetOpenAuth/issues/203

but that library is apparently no longer being maintained: https://github.com/DotNetOpenAuth/DotNetOpenAuth/issues/317#issuecomment-29580565

... although it is still referenced in many Microsoft documents. Investigating that related to another defect.
