title: .Net Framework and .Net Core in same solution
body: <p>I have an application targeting .NET Framework, and now I need to develop a library in .NET Core.
  I plan to put both projects in the same solution and add the .NET Core library as a reference in the .NET Framework project. </p>
  
  <p>Can this be done? If the answer is yes, how can this be done?</p>
