ASP.Net OpenAuth登录方法未找到System.Data.Entity.ModelConfiguration.EntityTypeConfiguration

问题描述：

我试图启用登录使用外部提供商，特别是Facebook的网络表格应用程序。ASP.Net OpenAuth登录方法未找到System.Data.Entity.ModelConfiguration.EntityTypeConfiguration

我使用asp.net 4.5 C＃和Entity Framework 6

本地帐户登录完美地工作，但是当我尝试使用Facebook帐户登录，我得到两个以下错误：

1 - 我第一次运行时尝试登录：

未找到方法：'System.Data.Objects.ObjectContext System.Data.Entity.Infrastructure.IObjectContextAdapter.get_ObjectContext（）'。 [堆栈跟踪]

[MissingMethodException: Method not found: 'System.Data.Objects.ObjectContext System.Data.Entity.Infrastructure.IObjectContextAdapter.get_ObjectContext()'.] 
    Microsoft.AspNet.Membership.OpenAuth.EFOpenAuthMembershipDatabase.EnsureDatabaseCreated(DbContext db) +0 
    Microsoft.AspNet.Membership.OpenAuth.EFOpenAuthMembershipDatabase.GetContext() +106 
    Microsoft.AspNet.Membership.OpenAuth.EFOpenAuthMembershipDatabase.GetMembershipUserName(String providerName, String providerUserId, Boolean updateLastUsed) +207 
    Microsoft.AspNet.Membership.OpenAuth.OpenAuthManager.Login(HttpContextBase context, String providerName, String providerUserId, Boolean createPersistentCookie) +285 
    Microsoft.AspNet.Membership.OpenAuth.OpenAuth.Login(String providerName, String providerUserId, Boolean createPersistentCookie) +109

然后 2 - 每次我尝试运行与Facebook登录一次：未发现

方法：“太虚System.Data.Entity.ModelConfiguration.EntityTypeConfiguration'1。 ToTable（System.String）” [栈跟踪]

[MissingMethodException: Method not found: 'Void System.Data.Entity.ModelConfiguration.EntityTypeConfiguration'1.ToTable(System.String)'.] 
    Microsoft.AspNet.Membership.OpenAuth.Data.OpenAuthDbContext.OnModelCreating(DbModelBuilder modelBuilder) +0

    Microsoft.AspNet.Membership.OpenAuth.OpenAuth.Login(String providerName, String providerUserId, Boolean createPersistentCookie) +109 
...]

这两个错误上升对以下行（OpenAuth.Login （）方法）在RegisterExternalLogin.aspx.cs：

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

的authResult对象具有正确的值，所以Facebook验证工作正常。 OpenAuth.Login方法在尝试写入数据库时出错，但我无法理解，因为在调试错误时我没有收到任何明确的详细信息。即使使用脚本调试，我也会得到该方法的错误页面，而没有其他的东西。

我已经安装了以下软件包：

<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" />

和OWIN如下：被提到OnModelCreating方法

<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" />

如在第一个错误的堆栈跟踪，这是：

 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>(); 
    }

答

问题出在包

Microsoft.AspNet.Membership.OpenAuth

这是版本1.0.1 升级到版本2它解决了使用外部帐户提供程序登录的问题。有可能是在第1版中的错误导致冲突与实体框架6如下报道：https://connect.microsoft.com/VisualStudio/feedback/details/811035/microsoft-aspnet-membership-openauth-is-not-compatible-with-entity-framework

这样做，因为我是用Microsoft.AspNet.Identity导致项目无限等问题*和身份和会员资格不兼容。

因此，我已经删除了与Microsoft.AspNet.Identity相关的所有内容，更改了用户，角色，成员资格等表的数据库模式。现在一切正常。
