title: Older version of .Net not installed with latest Mono?
body: <p>I've been working on a .NET 3.5 C# project using Visual Studio Community 2015, but I had always intended to do most of the development on Linux (Ubuntu Gnome 15.04) using Mono and MonoDevelop.</p>
  
  <p>I'm running the latest stable Mono release (4.0.4) and MonoDevelop (5.9.6), which supports .NET 4.5 and can open the VS created solution file without issue.</p>
  
  <p>Now I've been writing C++ apps on Linux for the best part of a decade, but C# and .NET are completely new to me.  So I <em>assumed</em> that if I installed a Mono version that supports .NET 4.5, I would get .NET 3.5 as well because the later version is a superset of the older - much like a C++14 compiler supports C++03.</p>
  
  <p>However this doesn't seem to be the case, as MonoDevelop states (under the Target Framework option for each project):</p>
  
  <ul>
  <li>.NET Framework 4.5.1</li>
  <li>Mono / .NET 4.5</li>
  <li>Mono / .NET 3.5 (Not installed)</li>
  </ul>
  
  <p>So do I have to install a parallel older version of Mono in order to get .NET 3.5 support, or am I just suffering a configuration problem?</p>
