基类包括字段“OpenAuthLogin”，但它的类型(OpenAuthProviders)与控件的类型不兼容

Question

我在is 2013/C#中有一个webforms应用程序，它使用使用vs2013向导生成的Owin身份验证，并将所有身份验证代码复制到我的旧webforms项目中，该项目使用.NET 4.5，但进行了openid身份验证，现在我更改为openauth2。

当我试图访问login.aspx页面时，会得到以下错误：

Server Error in '/' Application.

Parser Error

Description: An error occurred during the parsing of a resource required to
service this request. Please review the following specific parse error details
and modify your source file appropriately. 

Parser Error Message: The base class includes the field 'OpenAuthLogin',
but its type (OpenAuthProviders) is not compatible with the type of control 
(ASP.account_openauthproviders_ascx).

这是发生错误的行：

Line 18:      <section id="socialLoginForm">
Line 19:         <h2>Use a service to log in.</h2>
Line 20:         <uc:OpenAuthProviders runat="server" ID="OpenAuthLogin" />
Line 21:      </section>

Source File: /Account/Login.aspx    Line: 20 

这是删除连接字符串的web.config文件。

问题似乎在于，我从其中复制到身份验证代码的生成网站是一个Web项目，另一个是Web应用程序，需要不同的代码。
