<p>I keep getting this error trying to build a project opened as file => open web site.</p>

<p>This is not an MVC application and another suggestion I found online suggest deleting the content of the obj directory. I don't have an obj directory, not in C:\Users\Me\Documents\Visual Studio 2012\Projects\home.sln (2) nor in the web site directory.</p>

<p>Using Visual studio express 2012</p>
