title: How to migrate from BuildProvider to Web Application project?
body: <p>Currently we have a bunch of web sites (web site projects) that I think should be converted to web application projects. Everybody agrees.</p>
  
  <p>But a number of custom BuildProviders are used to generate controls and unfortunately <a href="http://msdn.microsoft.com/en-us/library/system.web.compilation.buildprovider.aspx" rel="nofollow noreferrer">MSDN says</a> that</p>
  
  <blockquote>
    <p>Adding a customized BuildProvider class to the Web.config file works in an ASP.NET Web site but does not work in an ASP.NET Web application project</p>
  </blockquote>
  
  <p>Are there some ways to migrate though without full discarding of custom BuildProviders mechanism?</p>
