Question

经常发生以下错误。我想知道是否有人经历过这个或者原因是什么？

我使用Entity Framework 4.0和。 NET 4.0和Visual Studio 2010以及Windows Azure SDK 1.7和2.0。

以下是连接字符串：

<add name="MyEntities" 
    connectionString="metadata=res://*/Model.ModelMy.csdl|res://*/Model.ModelMy.ssdl|res://*/Model.ModelMy.msl;
        provider=System.Data.SqlClient;
        provider connection string=&quot;
        data source=myserver.database.windows.net;
        initial catalog=MyDatabase;
        persist security info=True;
        user id=myUser;
        password=myPassword;
        multipleactiveresultsets=True;
        Trusted_Connection=False;
        Encrypt=True;
        Connection Timeout=30;
        App=EntityFramework&quot;" 
    providerName="System.Data.EntityClient"
 />

错误信息：

第1步：简化您的连接字符串。我们看起来像这样：

  <add name="[CONTEXTNAME]"
     providerName="System.Data.SqlClient"
     connectionString="
      Server=tcp:[SERVER].database.windows.net,1433;
          Database=[DATABASE];
          User ID=[USER]@[SERVER];
          Password=[PASSWORD];
          Trusted_Connection=False;
          Encrypt=True;
          Connection Timeout=30;"/>

所以看看你的连接字符串，我会尝试类似的东西：

  <add name="MyEntities"
     providerName="System.Data.SqlClient"
     connectionString="
          metadata=res://*/Model.ModelMy.csdl|res://*/Model.ModelMy.ssdl|res://*/Model.ModelMy.msl;
          Server=myserver.database.windows.net;
          Database=MyDatabase;
          User id=myUser@myserver;
          Password=myPassword;
          Multipleactiveresultsets=True;
          Trusted_Connection=False;
          Encrypt=True;
          Connection Timeout=30;
          App=EntityFramework;" />

第2步：看起来您“用户ID”缺少服务器名称。它需要是myUser @ myServer。尝试重新添加。

第3步：可能并不重要，但你错过了服务器地址中的“，1433”
