Question

我有一个asp.net mvc 4 Web应用程序，我在其中创建了一个自定义成员资格提供程序（继承自MembershipProvider基类）。在同一个解决方案中，但在另一个项目中，我有一个wcf服务，我想使用我的成员资格提供程序中的ValidateUser方法（称为KinematMembershipProvider）对用户进行身份验证

这是我的服务界面

[ServiceContract]
public interface IKinematService
{
    [OperationContract]
    bool AuthenticateUser(string username, string password);
}

和实际服务

public class KinematService : IKinematService
{
    public bool AuthenticateUser(string username, string password)
    {
        KinematMembershipProvider membershipProvider = (KinematMembershipProvider)Membership.Providers["KinematMembershipProvider"];
        return membershipProvider.ValidateUser(username, password);
    }
}

这是我的app.config文件

当我运行我的服务时，我收到以下错误 System.TypeLoadException：无法从程序集'System.Web，Version = 4.0.0.0，Culture = neutral加载类型'Kinemat.Web.Infrastructure.KinematMembershipProvider'公钥= b03f5f7f11d50a3a”。

我无法弄清楚它为什么要在System.Web程序集中搜索。请问您有什么建议吗？如果需要，请询问任何其他信息。谢谢。

Answer 1

它试图在System.Web程序集中找到它，因为您没有在配置中指定它应该实际搜索您的提供程序。尝试修改您的配置以包含如下所示的程序集名称：

<providers>
    <add name="KinematMembershipProvider" type="Kinemat.Web.Infrastructure.KinematMembershipProvider, Assembly.Name.Where.Provider.Resides" .../>
</providers>

在wcf服务错误中使用自定义成员资格提供程序
