实体框架：路径中的非法字符。（连接字符串）（MVC3）

我想在我的MVC3项目中使用实体框架。但每次我打电话Entities context = new Entities(); 我收到此错误：路径中的非法字符。我不知道这有什么与我的ConnectionString，这是如下：

metadata=res://*/Models.Model.csdl|res://*/Models.Model.ssdl|res://*/Models.Model.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=.\SQLEXPRESS;Initial Catalog=databasename;Persist Security Info=True;User ID=username;Password=password;MultipleActiveResultSets=True&quot;

我使用反射来找出正确嵌在我组装的资源是否，答案是肯定的，他们是完全嵌入在我的程序集Models.Model.csdl，.ssdl和.msl ...

我的模型是在我试图连接，并没有引用，这意味着通配符*应该在相同的程序集工作正常。

ConnectionString中是完全一样的按向导生成...

不幸的是，无效字符可能在用户名或密码。也许你可以发布他们炒？或者至少列出其中的字符类型？ – 2011-01-19 17:11:11

最后，取消之后SERVERNAME \ INSTANCE中的反斜杠开始工作。（在我的SQL Server实例中添加了一个别名，没有反斜杠）。也许可以解决以及通过使用web.config删除非法字符的反斜杠...它如何获得该列表仍然未知
