我試圖啓用登錄使用外部提供商，特別是Facebook的網絡表格應用程序。ASP.Net OpenAuth登錄方法未找到System.Data.Entity.ModelConfiguration.EntityTypeConfiguration
我使用asp.net 4.5 C＃和Entity Framework 6
本地帳戶登錄完美地工作，但是當我嘗試使用Facebook帳戶登錄，我得到兩個以下錯誤：
1 - 我第一次運行時嘗試登錄：
未找到方法：'System.Data.Objects.ObjectContext System.Data.Entity.Infrastructure.IObjectContextAdapter.get_ObjectContext（）'。 [堆棧跟蹤]
[MissingMethodException: Method not found: 'System.Data.Objects.ObjectContext System.Data.Entity.Infrastructure.IObjectContextAdapter.get_ObjectContext()'.]

然後 2 - 每次我嘗試運行與Facebook登錄一次：未發現

這兩個錯誤上升對以下行（OpenAuth.Login （）方法）在RegisterExternalLogin.aspx.cs：
if(OpenAuth.Login(authResult.Provider, authResult.ProviderUserId, createPersistentCookie: false))
{
RedirectToReturnUrl();
}
的authResult對象具有正確的值，所以Facebook驗證工作正常。 OpenAuth.Login方法在嘗試寫入數據庫時出錯，但我無法理解，因爲在調試錯誤時我沒有收到任何明確的詳細信息。即使使用腳本調試，我也會得到該方法的錯誤頁面，而沒有其他的東西。
我已經安裝了以下軟件包：
<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.RelyingParty" version="4.1.4.12333" targetFramework="net45" />
和OWIN如下：被提到OnModelCreating方法

<package id="Microsoft.Owin.Host.SystemWeb" version="3.0.1" targetFramework="net45" />

如在第一個錯誤的堆棧跟蹤，這是：
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>();
