As it ships today, ASNA Visual RPG 14.0 continues to offer optional support for the .NET 2.0-3.5 Frameworks. That optional support can be downloaded from our devnet.asna.com site.
Microsoft ended all support for the .NET 2.0 Framework on April 12, 2016. At some point in the near future we’ll be dropping the optional support for the .NET 2.0-3.5 Frameworks. This is generally not a big issue, but does require you to recompile your projects with a newer target .NET Framework selected. .NET 4.5.2 is the most current, and recommended, version to use.
The best plan now is as you make changes and redeploy your AVR for .NET apps, pay close attention to their .NET Framework requirements and upgrade them as you go. That will better prepare you for the time when AVR for .NET no longer supports those older .NET Frameworks.
