Hi Jon,
[quote user="Jon Summers"]Should we be using Viz Studio 2015 for native code?[/quote]
From Bob's announcement: MicroStation CONNECT Edition MDL applications compiled with previous version of the SDK are both binary and source code compatible with this release. ... so Visual Studio 2013 is still required. I don't believe C++ compiler can be changed without breaking binary compatibility.

Maybe it's a preparation for changes in future? From Bob's info: Update 4 will provide expected enhancements in a very near future update cycle release.
Visual Studio 2015 brings a lot of (and important) changes in C++ compiler, so it would be nice to move to this version, but I assume it's pretty complex change with external libraries and frameworks used internally in MicroStation.
With regards,
Jan
