Question

当我创建一个新的asp.net webform .net 4.0并且我配置AuthConfig.cs时，我正在使用Microsoft.AspNet.Membership.OpenAuth：

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

在Facebook应用配置中： Facebook登录网站：http://www.tindep.com

但是当我使用facebook登录时出现错误：

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.

Exception Details: System.Net.WebException: The remote server returned an error: (400) Bad Request.

Source Error:

Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.18055

虽然Google，Twitter，msdn登录成功（查看tindep.com/Account/Login.aspx）这是托管时唯一的错误（tindep.com/Account/Login.aspx）。 localhost：57846 / Account / Login.aspx登录facebook成功。

请帮助我找到原因。

非常感谢！

有一个与此相关的缺陷： https://github.com/DotNetOpenAuth/DotNetOpenAuth/issues/203

但显然不再维护该库： https://github.com/DotNetOpenAuth/DotNetOpenAuth/issues/317#issuecomment-29580565

...虽然在许多Microsoft文档中仍然引用它。调查与另一个缺陷相关的问题。
