title: Visual studio 2013 builds every time unnecessarily and is slow
body: <p>I have Visual Studio profession 2013. .NET framework installed 4.5. </p>
  
  <p>My Visual studio is giving me some problems. When i run it builds every single time.Takes up a good 2 minutes to build. If i change a class then i understand it should build, but not every time i make a change to .aspx or .aspx.vb page. it did not work this way for Visual studio 2012. Is there any setting I am not seeing?Language being built in is VB. Should i change any setting value? Is there any IIS express value I need to set?
   If you need more info,please ask.Thanks</p>
