For those who have missed this, its at https://www.visualstudio.com/en-us/news/vs2015-update2-vs.aspx

I think that these two improvements are gems:

• Universal Windows SDK Version Picker. When creating a new UWP project, you can now select the version of the Windows SDK to target as well as the minimum OS version on which the apps are to be available.
• Debugging C++ Background Task in Universal Windows Apps. You can now debug Background task processes in a Universal Windows app in Visual Studio. You can access this option on the project Properties Debug tab.

PS: Has anyone tried Compact 2013 Platform Builder and App Development with this release.  Have they made it through unscathed?

I’ll try Iot-Core tomorrow.
