We just released AutoCAD .NET Addin Wizard 2015 (AcadNetAddinWizardPro 2.x), which supports the latest Visual Studio version 2015 along with 2013 and 2012. It still supports C#, VB.NET, and CLI/C++ project wizards. All item wizards, widgets and coders still work with both C# and VB.NET.
In terms of AutoCAD, it supports the latest version 2016 as well, along with many old but still popular versions. As always, it also supports almost all of the AutoCAD flavors. As usual, it supports not only .NET DLLs but also COM Interop libraries.
We are going to do the same to Revit .NET Addin Wizard Professional, upgrade to the Visual Studio Extension from the Addin. It can be expected done soon. Please stay tuned.
