title: .Net Core and Full Framework projects in one solution
body: <p>Say I have a solution with several projects included. One of projects is Main (where general code and APIs are placed) and the rest are kind of extensions (Extension1, Extension2, Extension3) for the Main and use third-party libraries. Now I'm making the solution compatible on both Full Framework and .Net Core Framework.</p>
  
  <p>The solution had already had conditional building process depending on target framework before I started adding support for .Net Core, so I have no problems with conditional building yet.</p>
  
  <p>The problem what I do have is that part of third-party libraries is not compatible with .Net Core yet. That makes a part of the extensions incompatible with .Net Core. The only option that comes to my mind is to have separate solutions and code bases for full framework and .Net Core Framework. BUT I would like to have same code base in both cases because my code is pretty compatible with both frameworks and otherwise it would be such a pain in the neck to support.</p>
  
  <p>Is it possible to have only one solution for that case and be able to build (Main + (Extension1, Extension2, Extension3)) projects for full framework and (Main + (Extension1, Extension2)) for .Net Core Framework? If it's not, what options do I have?</p>
  
  <p>Thank you all in advance</p>
