C# 找不到ASP.Net OpenAuth登录方法System.Data.Entity.ModelConfiguration.EntityTypeConfiguration

我正在尝试使用外部提供商启用登录，特别是在网络表单应用程序中的Facebook

我正在使用asp.NET4.5C和实体框架6

本地帐户登录工作正常，但当我尝试使用facebook帐户登录时，会出现以下两个错误：

1-在我第一次运行时，请尝试登录：

未找到方法：“System.Data.Objects.ObjectContext System.Data.Entity.Infrastructure.IOObjectContextAdapter.get_ObjectContext（）”。 [StackTrace]

然后 2-每次我尝试再次使用facebook登录时：

未找到方法：“Void System.Data.Entity.ModelConfiguration.EntityTypeConfiguration”1.ToTable（System.String） [StackTrace]

[MissingMethodException: Method not found: 'System.Data.Objects.ObjectContext System.Data.Entity.Infrastructure.IObjectContextAdapter.get_ObjectContext()'.]

...]

这两个错误都出现在RegisterExternalLogin.aspx.cs中的以下行（OpenAuth.Login（）方法）中：

if(OpenAuth.Login(authResult.Provider, authResult.ProviderUserId, createPersistentCookie: false))
        {
            RedirectToReturnUrl();
        }

authResult对象具有正确的值，因此facebook身份验证工作正常。 当OpenAuth.Login方法试图写入DB时，它出现了一些错误，但我不明白是什么，因为我在调试错误时没有收到任何明确的细节。即使使用step in debug，我也会得到该方法的错误页面，而不会得到其他任何东西

我已安装以下软件包：

<package id="DotNetOpenAuth.AspNet" version="4.1.4.12333" targetFramework="net45" />
<package id="DotNetOpenAuth.Core" version="4.1.4.12333" targetFramework="net45" />
<package id="DotNetOpenAuth.OAuth.Consumer" version="4.1.4.12333" targetFramework="net45" />
<package id="DotNetOpenAuth.OAuth.Core" version="4.1.4.12333" targetFramework="net45" />
<package id="DotNetOpenAuth.OpenId.Core" version="4.1.4.12333" targetFramework="net45" />
<package id="DotNetOpenAuth.OpenId.RelyingParty" version="4.1.4.12333" targetFramework="net45" />

以及以下有关OWIN的信息：

<package id="Microsoft.Owin" version="3.0.1" targetFramework="net45" />
<package id="Microsoft.Owin.Host.SystemWeb" version="3.0.1" targetFramework="net45" />
<package id="Microsoft.Owin.Security" version="3.0.1" targetFramework="net45" />
<package id="Microsoft.Owin.Security.Cookies" version="3.0.1" targetFramework="net45" />
<package id="Microsoft.Owin.Security.Facebook" version="3.0.1" targetFramework="net45" />
<package id="Microsoft.Owin.Security.Google" version="3.0.1" targetFramework="net45" />
<package id="Microsoft.Owin.Security.MicrosoftAccount" version="3.0.1" targetFramework="net45" />
<package id="Microsoft.Owin.Security.OAuth" version="3.0.1" targetFramework="net45" />
<package id="Microsoft.Owin.Security.OpenIdConnect" version="3.0.1" targetFramework="net45" />
<package id="Microsoft.Owin.Security.Twitter" version="3.0.1" targetFramework="net45" />

正如在第一个错误的堆栈跟踪中提到的OnModelCreating方法一样，它是：

        protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder); // This needs to go before the other rules!

        modelBuilder.Entity<User>().ToTable("Users").Property(p => p.Id).HasColumnName("UserId");
        modelBuilder.Entity<IdentityUserRole>().ToTable("UserRoles");
        modelBuilder.Entity<IdentityUserLogin>().ToTable("UserLogins");
        modelBuilder.Entity<IdentityUserClaim>().ToTable("UserClaims").Property(p => p.Id).HasColumnName("UserClaimId");
        modelBuilder.Entity<IdentityRole>().ToTable("Roles").Property(p => p.Id).HasColumnName("RoleId");
        modelBuilder.Ignore<IdentityUser>();
    }

模型创建时受保护的覆盖无效（DbModelBuilder modelBuilder）
{
base.OnModelCreating（modelBuilder）；//这需要在其他规则之前执行！
modelBuilder.Entity（）.ToTable（“Users”）.Property（p=>p.Id）.HasColumnName（“UserId”）；
modelBuilder.Entity（）.ToTable（“用户角色”）；
modelBuilder.Entity（）.ToTable（“用户登录”）；
modelBuilder.Entity（）.ToTable（“UserClaims”）.Property（p=>p.Id）.HasColumnName（“UserClaimId”）；
modelBuilder.Entity（）.ToTable（“Roles”）.Property（p=>p.Id）.HasColumnName（“RoleId”）；
Ignore（）；
}

问题出在程序包中

Microsoft.AspNet.Membership.OpenAuth

那是1.0.1版 升级到版本2可以解决使用外部帐户提供商登录的问题。 版本1中可能存在导致与Entity Framework 6冲突的错误，如下所述：

当我使用Microsoft.AspNet.Identity.*时，这样做会在项目中造成无限的其他问题，而Identity和Membership是不兼容的

因此，我删除了与Microsoft.AspNet.Identity相关的所有内容，更改了用户、角色、成员等表的DB模式。 现在一切都很好
