Thanks for the report, @drarsalan

The attribute "Version" in element is unrecognized.

More like because of unrelated schema.

Can you also attach this project file (.csproj etc) ? Seems problem again with backward compatibility exactly in MS internal logic as for #2

Temporarily, you can try to override IsolatedEnv.Load with own logic

https://github.com/3F/MvsSln/blob/a84f0f246aaf571ce6f44f151369472711b2a635/MvsSln/Core/IsolatedEnv.cs#L333

Like we use this also in DllExport project to avoid some related problems:

@drarsalan https://github.com/3F/MvsSln/issues/5#issuecomment-410464661 solves problem via other version of Microsoft.Build.dll. Check this out.

(.netfx 4.6+ for today)
