Connecting SQL with Windows form application

I am开发者_JS百科 trying to connect my form application with SQL client. When I am trying to connect by clicking data---->add new data Source=--->New Connection and I selected the Microsoft SQL Server Database File (SqlClient) and selected my database named dish_Tv.mdf. After selecting I clicked the Test Connection button it says

User instance login flag is not supported on this version of sql server.the connection will be closed.

Can anyone help me out solving this error? Thanks in advance.

SQL Server 2005(Full Version) does not support the "user instance"(automatic creation of databases from code) directive in the connection string. Its a feature of sql server express edition.
