@zeusongit @QilongTang @aparajit-pratap do you think the build should fail if this transform fails? Right now it does not.

[mjkkirschner]

@zeusongit this looks good, I just have two questions.

[QilongTang]

I dont think the build should fail for everyday user.. 3rd party dev should not worry about this I think. @mjkkirschner @aparajit-pratap What do you think?

[QilongTang]

I am going to merge this, at the same time uninstalling VS2017 locally on my machine to test this
