How build older version projects in VS2015 : <p>I am trying to compile this <a href="https://code.msdn.microsoft.com/Using-the-DropDownList-67f9367d" rel="nofollow noreferrer">old project(link to old project)</a> But I am getting a lot of missing namespaces which cannot be resolved. Usually, when I open older projects I can resolve these by clicking the lightbulb and import correct namespace but there are none suggested.</p>
