title: SQL server and c# applications over network
body: <p>I created a C# application that uses .mdf database and it works perfectly on my PC. 
  Now i wanted to install that application on network PCs that can connect to a single database and use that data. 
  I tried changing the connection string in application with only changing file path, but it doesn't work. How can i use one PC as server and use program as client application that can connect over network. How do i set up SQL server on that PC, and should i do that? How is this done? I couldn't find any tutorial so far... </p>
  
  <p>Could someone help me a bit. </p>
