title: Developer specific app.config/web.config files in Visual Studio
body: <p>We have several .NET projects where we store certain settings in configuration files.</p>
  
  <p>Now each developer will have their own configuration files that differ a little (different connection strings to connect to local databases, different <a href="https://en.wikipedia.org/wiki/Windows_Communication_Foundation" rel="noreferrer">WCF</a> endpoints, etc.)</p>
  
  <p>At the moment we tend to check out app/web.config files and modify them to suit our needs.</p>
  
  <p>This leads to many problems since from time to time someone will check in their own settings or loose custom configuration when getting latest version from <a href="https://en.wikipedia.org/wiki/Team_Foundation_Server" rel="noreferrer">TFS</a>.</p>
  
  <p>How do you deal with situations like this? Or don't you have this problem at all?</p>
