当我的Razor视图调用@ Html.OpenIdSelector时(…我得到一个InvalidOperationException：
The current IHttpHandler is not one of
types: System.Web.UI.Page,
DotNetOpenAuth.IEmbeddedResourceRetrieval.
An embedded resource URL provider must
be set in your .config file.
我应该在配置文件中设置什么？
解决方法
只需
NuGet DotNetOpenAuth包.它将在配置文件中设置您需要的所有内容：
>在解决方案资源管理器中右键单击Web项目的引用
>添加库包参考…
>单击“在线”选项卡.
>在搜索框中键入dotnetopenauth
>单击“安装”
一切都将自动设置,正确的组件将从互联网上下载并作为参考添加.
以下是执行此操作后web.config文件的外观：

更新：
您可以实现自定义资源检索提供程序：
public class CustomResourceProvider : IEmbeddedResourceRetrieval
{
public Uri GetWebResourceUrl(Type someTypeInResourceAssembly,string manifestResourceName)
{
return new Uri("http://www.google.com");
}
}
然后在web.config中注册它：
<dotNetOpenAuth>
<webResourceUrlProvider type="AppName.CustomResourceProvider,AppName" />
...
</dotNetOpenAuth>
但我建议您使用openid-selector库生成登录表单.
