试图远程运行selenium 2脚本(Trying to run selenium 2 scripts remotely)

 System.Data.Entity.Infrastructure.SqlConnectionFactory不打算以这种方式使用。 这个连接工厂包含一个构造函数，它允许我们覆盖最终连接sting的部分，例如用户名，密码和服务器，而不是整个东西。 

 例如，我们可以像这样更改数据库服务器： 
 
Database.DefaultConnectionFactory = 
        new SqlConnectionFactory("Server=MyDatabaseServer"); 
 
 您可以通过在app.config中提供与 DbContext名称匹配的连接字符串来轻松完成此处尝试的操作 - 我假设它是PicturesCatalog ： 
 
<connectionStrings>
   <add name="PicturesCatalog" connectionString="data source=.; 
        Initial Catalog=PicturesDatabase; Trusted_Connection=True;"
        providerName="System.Data.SqlClient" />
</connectionStrings>

System.Data.Entity.Infrastructure.SqlConnectionFactory is not meant to use in this way. This connection factory includes a constructor that allows us to override pieces of the final connection sting, such as username, password and server and not the whole thing. 

 For example, we can change the Database Server like this:
 
Database.DefaultConnectionFactory = 
        new SqlConnectionFactory("Server=MyDatabaseServer"); 
 
What you try to do here can be easily accomplished by providing a connection string in your app.config that matches the name of your DbContext - I assume it's PicturesCatalog:
 
<connectionStrings>
   <add name="PicturesCatalog" connectionString="data source=.; 
        Initial Catalog=PicturesDatabase; Trusted_Connection=True;"
        providerName="System.Data.SqlClient" />
</connectionStrings>
