ASP.NET應用程序7

Question

我們只是建立一個新的PCI兼容的服務器，當我部署我的asp.net應用它，我得到這個錯誤信息：

與ADO.NET提供商不變的名稱「System.Data.SqlClient」未在計算機或應用程序配置文件中註冊，或者無法加載。詳情請參閱內部例外。

我再次檢查我的配置文件，卸載EF並重新安裝它在所有的項目。我在部署後看到bin文件夾中的DLL（我們使用CI和team city和octopus）。我在網上查了幾乎所有的帖子，以找到沒有成功的解決方案

當我將這個應用程序部署到非PCI兼容服務器時，它工作正常。我不知道什麼會導致它！

的web.config

<configSections> 
 
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false"/> 
 
    </configSections> 
 

 
<!-- Connection String --> 
 
<add name="BondedBuilderModel" connectionString="data source=SqlServer;initial catalog=mydb;integrated security=false;User Id=user; Password =pass;MultipleActiveResultSets=True;App=EntityFramework" providerName="System.Data.SqlClient"/> 
 
     
 

 
<!-- Provider --> 
 
    <entityFramework> 
 
     <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework"> 
 
      <parameters> 
 
       <parameter value="System.Data.SqlClient"/> 
 
      </parameters> 
 
     </defaultConnectionFactory> 
 
     <providers> 
 
      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer"/> 
 
     </providers> 
 
    </entityFramework>

** **異常

The ADO.NET provider with invariant name 'System.Data.SqlClient' is either not registered in the machine or application config file, or could not be loaded. See the inner exception for details.

Answer 1

對於通過這個運行的任何人，終於想通了。
在machine.config文件：

32位

%windir%\Microsoft.NET\Framework\[version]\config\machine.config 

64位

%windir%\Microsoft.NET\Framework64\[version]\config\machine.config 

有限定的dbproviders截面，但它還有一個右後一個像這樣定義<DbProviderFactories/>

一旦第二個被刪除，應用程序開始工作，上面的錯誤停止顯示。
問題仍然是爲什麼機器配置中定義了兩個部分。沒有人手動編輯這個文件！
