title: SQL server & Visual Studio
body: <p>I need help with SQL server in visual studio. I can't seem to connect my visual studio with internal SQL server. I had created a database with visual studio earlier and it was working fine but now i'm getting an error saying:</p>
  
  <blockquote>
    <p>The attempt to attach to the database failed with the following
    information: A network-related or instance-specific error occurred
    while establishing a connection to SQL Server. The server was not
    found or was not accessible. Verify that the instance name is correct
    and that SQL Server is configured to allow remote connections.
    (provider: SQL Network Interfaces, error: 50 - Local Database Runtime
    error occurred. Cannot create an automatic instance. See the Windows
    Application event log for error details.</p>
  </blockquote>
  
  <p>I have tried to create a new database file in a new project but then i get the error:</p>
  
  <blockquote>
    <p>A network related or instance specific error occurred while
    establishing a connection. The server was not found or was not
    accessible. (Provider:Named Pipes Provider, error:40- could not open a
    connection to SQL server.</p>
