如何讓Glimpse與EF6一起使用？

我有一個ASP.NET MVC 5項目，通過實體框架6.使用SQL Server數據庫

我加入掠影（和Glimpse.MVC5）的項目，並且工作正常。

但是，當我添加Glimpse.EF6時，我的應用程序一嘗試訪問數據庫就會引發異常。唯一的例外是：

System.NotSupportedException

無法確定類型的供應商工廠的供應商名稱 'System.Data.SqlClient.SqlClientFactory'。確保在應用程序配置中安裝或註冊了ADO.NET提供程序。

發生了什麼事？僅供參考，我的web.config的connectionStrings部分看起來是這樣的：

<connectionStrings> 
    <add name="DefaultConnection" connectionString="Data Source=.; Initial Catalog=foo; Integrated Security=True; MultipleActiveResultSets=True;" providerName="System.Data.SqlClient" /> 
</connectionStrings>

...我Application_Start方法是這樣的：

protected void Application_Start() 
{ 
    AreaRegistration.RegisterAllAreas(); 
    GlobalConfiguration.Configure(WebApiConfig.Register); 
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); 
    RouteConfig.RegisterRoutes(RouteTable.Routes); 
    BundleConfig.RegisterBundles(BundleTable.Bundles); 

    Database.SetInitializer(new WebApplication.Models.Storage.ApplicationDbInitializer()); 
}

...和我的上下文類看起來是這樣的：

public class ApplicationDbContext : IdentityDbContext<ApplicationUser> 
{ 
    public ApplicationDbContext() 
     : base("DefaultConnection") 
    { 
    } 

    public DbSet<Foo> Foos { get; set; } 
}

在此先感謝您的幫助......

您可以添加堆棧跟蹤嗎？或者甚至更好，在[我們的問題跟蹤器]（https://github.com/glimpse/glimpse/issues）上創建問題，因爲這聽起來不像你做錯了什麼。就像快速檢查一樣，當您將Database.SetInitializer置於註釋中時，是否也有相同的問題？ – cgijbels

@cgijbels：刪除Database.SetInitializer沒有區別。我將添加堆棧跟蹤並創建一個問題。 –

@cgijbels：添加爲[issue 173]（https://github.com/Glimpse/Glimpse/issues/713）。謝謝。 –

對於那些尋找一個解決辦法：

它看起來就像是一個bug within EF itself（它被提及爲173以上，但鏈接是正確的）。您可以等待EF 6.1.1/6.2，或者您可以降級到EF 6.0.2，並且它將重新開始工作。

在Package Manager控制檯，輸入：

Install-Package EntityFramework -Version 6.0.2

，你應該是好去。

但只有當EF 6.0.2是您的選擇。祝你好運。

回滾到6.0.2無助於那些使用Identity 2.0的人 – ScottE

正確 - 感謝您指出@ScottE。希望EF的下一個版本能夠快速出來並解決此問題。 – PRB

我已經回滾到6.0.2，仍然有一個問題.. 有沒有人得到它排序？ –

嘗試添加以下到您的配置文件

<configuration> 
    <configSections>  
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" /> 
    </configSections> 
    <entityFramework> 
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" /> 
    <providers> 
     <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" /> 
    </providers> 
    </entityFramework> 
</configuration>

我已經有了類似的東西（我沒有顯示整個web.config文件 - 只有'connectionStrings'元素），但有趣的是我的'defaultConnectionFactory'被設置爲本地數據庫提供者。無論如何，我改變它與你的建議相同，不幸的是它沒有什麼區別 - 我仍然得到同樣的錯誤。 –

另外，我應該補充，當我刪除Glimpse.EF6時，我所有的數據庫訪問都可以正常工作。這似乎是當我添加Glimpse.EF6時，它一切都出錯了。 –

哇，安裝Glimpse.EF6似乎已經永久隱藏了我的項目，即使完全卸載Glimpse後，我也無法擺脫此錯誤。我被迫從備份恢復整個項目！ –

如何讓Glimpse與EF6一起使用？
