Removing EnvDTE features

[3F]

net.r_eg.MvsSln.EnvDTE

Scheduled for removal in future major releases!

These features were added together with features from DllExport project when it was based on PowerShell scripts in the past (ie. obsolete today).

Today's MvsSln 2.x has been focused for work with data outside of Visual Studio IDE. And I don't see the future in the development of this thing for MvsSln.

Although it can be also separated into other independent project for more complex work with IDE/COM interop.

I want to hear some feedback for this. Because some other parts of related features already exists in vsSolutionBuildEvent + something new if it is in demand.

But anyway, I think this subset will no longer be as part of MvsSln.
