Upgrade .NET Framework

Hi everyone

Actually we use .NET Framework 4 for addon and some SBO development. So, .NET Framework 4 it's technology that is more than 10 years old (year 2010). The question is... There're any possibility to upgrade the .NET Framework technology for use some recent version? For example, .NET Framework 4.6 or newer...

Exists any site or Roadmap for looking any news about this?

Thanks :)
