Connect Local Database Mdf Visual Studio

I have created a mdf database from visual studio 2013 and stored some informations in the table. My problem is I can`t connect to my local database and select informations from tab

Solution 1:

You can't directly use database file. You have to access it through DB server. Update your query string, you can find the proper connection strings Here. If you don't have Management studio installed, you can use the SQLExpress instance installed by default in MS STUDIO, the connection string is HERE .
