连接到SQL Azure数据库时出错

经常出现以下错误。我想知道有没有人经历过这个或者是什么原因？连接到SQL Azure数据库时出错

我使用实体框架4.0和。 NET 4.0和Visual Studio 2010以及Windows Azure SDK 1.7和2.0。

下面是连接字符串：

<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。我们是这样的：

<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;"/>

所以看你的连接字符串，我会尝试这样的：

<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 [email protected]; 
      Password=myPassword; 
      Multipleactiveresultsets=True; 
      Trusted_Connection=False; 
      Encrypt=True; 
      Connection Timeout=30; 
      App=EntityFramework;" />

步骤2：看起来你“用户ID”丢失的服务器名称。它需要是myUser @ myServer。尝试添加回来。

步骤3：可能不是关键，但你错过了服务器地址的“，1433”
