title: Prevent ASP.NET Website project from building certain directories by using Web.config?
body: <p>While programming, the longest part is a build on my ASP.NET Website project is the "Building directory" process seen below. <em>(Note: I don't have the liberty to turn this into a Web Application with a .csproj build file. Wish I did.)</em></p>
  
  <p>The contents of the directories seen below are not changing although there might be some dependencies in the App_Code/ subfolders that do change.</p>
  
  <p><strong>Is there any way for me to stop some directories from building using Web.config</strong>, to shorten a compile of my dev copy? It's the only viable file I can think of to use without having an official build file.</p>
