The ProjectDir could exist under certain circumstances (e.g. referenced assemblies are being copied to the Mac in the same folder path that those are located in Windows) so we cannot assume the existence or not of ProjectDir means the build comes from VS.
The only way to ensure we're building from VS is to check the SessionId parameter.

I'm not 100% sure when --link was added to ibtool, but since our
release notes say that we now require Xcode >= 7.2 anyway, might
as well make that version a requirement for ibtool --link
(Based on forum comments, we know it didn't exist in Xcode 7.0 Beta 3)
* [msbuild] Even iOS Simulator builds now require signing certificates (#809)
Now that dylibs and frameworks are required to be signed in order to
run on the Simulator, we cannot allow the DetectSigningIdentity task
to return success if it didn't find a codesign key.
* [msbuild] Allow codesigning Simulator builds w/o the need of a developer cert (#833)
Now that dylibs and frameworks are required to be signed in order to
run on the Simulator, we cannot allow the DetectSigningIdentity task
to return success if it didn't find a codesign key.
* [msbuild] Support ibtool output when it adds ~ipad or ~iphone modifiers
When targetting older iOS versions (such as iOS 7) for multiple
device targets (e.g. iphone, ipad, etc), ibtool will output
multiple directories using the basename of the original ib file
and add ~ipad or ~iphone blurbs to the filename.
This was causing the linking step to fail due to paths not being
found at the expected locations.
* [msbuild] Added unit tests for ibtool --link w/ --minimum-deployment-target 7.0
Since pre-iOS 8.0 does not support size classes in storyboards,
ibtool will output LaunchScreen~ipad.nib and LaunchScreen~iphone.nib.
This test will fail if the IBTool logic does not properly determine
the outputs to pass to a final ibtool --link command to link all of
the storyboards together.
* [msbuild] Remove unnecessary duplicate implementation of Move
Our implementation of the Move task was a partial copy of what
the MSBuild Move task does: https://github.com/Microsoft/msbuild/blob/master/src/XMakeTasks/Move.cs
Remove the unnecessary code, make it inherit the base implementation
like we do for the other MSBuild-overriden tasks, and place it in a
corresponding MsBuildTasks folder to denote this (again, like we do
in iOS.Tasks).
Removing this (unnecessary IMO) custom implementation of Move
ensures that when we switch to MSBuild, we can leverage improvements
and fixes on the task automatically.
* [msbuild] Move all the common MSBuild overriden tasks to MacDev
These tasks previously existed in iOS.Tasks, and Mac.Tasks. Since
they are reused across iOS and XM targets, move them to the common
MacDev project and update the targets accordingly.
Starting with Xcode 7, storyboards are output as
Interface.storyboardc/Interface.plist instead of Interface.plist
We can also safely link these storyboards as long as we pass
the storyboardc directory to ibtool.
