title: Can I add a reference to a .NET Framework DLL from a .NET 5 project?
body: <p>Microsoft recently announced at Build 2019 that the next major version of .NET will unify both .NET Core 3.* and .NET Framework 4.* into a single .NET platform, which the major version number will be 5.</p>
  
  <p>I didn't understand it well, does it mean that using .NET 5 I will be able to add references to libraries written in both version of .NET?</p>
  
  <p>For example, a .NET 5 project referencing 2 assemblies, one that was compiled targeting .NET Core 3 and another compiled targeting .NET Framework 4.5 (in this case, as it references a .NET Framework library, I think it would only be able to run on Windows).</p>
