.net - How to kill localdb process after exit application -

I am developing winform application.

Below the connection string of my DB;

  string _DatabaseFile = path. Gate directory name (application.ExecutablePath) + @ "\ database \ db.mdf"; _DatabaseConnectionParams = String.Format (@ "Data Source = (LocalBible) \ v11.0; Attach DBFilName = {0}; Integrated Security = True", _DatabaseFile);  

Hiring works fine

But the SQL Server process continues to work after I quit my application.

Which approach is good to stop SQL Server?

Thank you in advance.

I do not think you need to do

< / P>

After the last connection to this process closes, it automatically closes a few minutes.
