我的网站最初是使用 VS2010 用 MVC 4.0 RC 编写的，.
我刚刚下载并安装了VS2012，并将我的项目升级到Dotnet Framework 4.5。

在我的项目中，我使用了自定义 MemberShipProvider 和自定义 RoleProvider。在 VS2010 上，它就像一个魅力。但现在我不断收到一个奇怪的配置错误:

“在应用程序的预启动初始化阶段无法调用此方法。”

我的 web.config 中的“system.web -> members -> providers -> add”行被标记为红色作为问题的根源。

我通过创建一个新的 MVC 4.0 项目(在 VS2012 中)、添加我的自定义成员资格/角色提供程序、适本地更改 web.config 并发现错误再次出现，从而消除了问题与迁移过程有关的怀疑!

深入研究问题 - 我在应用程序日志中发现了以下信息:

这是相关的自定义成员资格(我已对其进行了简化，但即使问题仍然存在)代码，只有 ValidateUser 真正被覆盖:

using System;
using System.Linq;
using System.Web.Security;
using DAL.MyWebSite;

namespace MyWebSite.Security
{
    public class MyWebSiteMembershipProvider : MembershipProvider
    {




        /// <summary>
        /// Verifies that the specified user name and password exist in the data source.
        /// </summary>
        /// <returns>
        /// true if the specified username and password are valid; otherwise, false.
        /// </returns>
        /// <param name="username">The name of the user to validate. </param><param name="password">The password for the specified user. </param>
        public override bool ValidateUser(string username, string password)
        {
            // simplified
            return true;
        }



    }
}

这是(简化的)角色提供者:

using System;
using System.Linq;
using System.Web.Security;
using DAL.MyWebSite;

namespace MyWebSite.Security
{
    public class MyWebSiteRoleProvider : RoleProvider
    {


        //readonly MyWebSiteDbContext _context = new MyWebSiteDbContext();
        /// <summary>
        /// Gets a value indicating whether the specified user is in the specified role for the configured applicationName.
        /// </summary>
        /// <returns>
        /// true if the specified user is in the specified role for the configured applicationName; otherwise, false.
        /// </returns>
        /// <param name="username">The user name to search for.</param><param name="roleName">The role to search in.</param>
        public override bool IsUserInRole(string username, string roleName)
        {
            return true;
            //return GetRolesForUser(username).Contains(roleName);
        }

        /// <summary>
        /// Gets a list of the roles that a specified user is in for the configured applicationName.
        /// </summary>
        /// <returns>
        /// A string array containing the names of all the roles that the specified user is in for the configured applicationName.
        /// </returns>
        /// <param name="username">The user to return a list of roles for.</param>
        public override string[] GetRolesForUser(string username)
        {
            return new string[] {"one", "two"};

            //var sm = _context.SalesManagers.Include("PermissionLevel").FirstOrDefault(manager => manager.UserName == username);

            //if (sm != null)
            //{
            //    if (sm.PermissionLevel.Name == "Sales Manager")
            //    {
            //        return new[] { "SalesManagers" };
            //    }

            //    if (sm.PermissionLevel.Name == "Administrator")
            //    {
            //        return new[] { "SalesManagers", "Administrators" };
            //    }

            //} 
            //return null;

        }

    }
}

我在自 MVC2 中使用我自己的自定义成员资格和角色提供程序，并在从 MVC3 迁移到 4 时遇到了这个问题。

我在 MVC4/.net4.5 EF5 中创建了一个新项目，但不幸遇到了这个错误。

我设法通过执行以下操作来修复它:

将此添加到您的 webconfig appsettings:

  <appSettings>
    <add key="enableSimpleMembership" value="false"/>
    <add key="autoFormsAuthentication" value="false"/>
  </appSettings>

如果尚未设置，请将您的连接字符串添加到您的成员资格和角色提供者:

<membership defaultProvider="MyMembershipProvider">
  <providers>
    <add name="MyMembershipProvider" type="AMS.WebUI.Infrastructure.CustomMembershipProvider" connectionStringName="EFDbContext" />
  </providers>
</membership>
<roleManager defaultProvider="MyRoleprovider">
  <providers>
    <add name="MyRoleprovider" type="AMS.WebUI.Infrastructure.CustomRoleProvider" connectionStringName="EFDbContext" />
  </providers>
</roleManager>

这解决了我的问题，我希望它可以帮助你。
