running a web application from unitests with selenium

Im using selenium to test baselines of screen shots of my product and trying to run an automated tests within tfs 2013 build which i got installed on another machine but for me to run the tests first i need to run the website from VS so the iis will host it and than the tests will run correctly

im searching for a C# code for running the web app[which is a child of default Web site ] anyone got any idea?
