I am not sure whether Azure Data Factory project is supported on Visual Studio 2017 at the moment.
I have just installed VS 2017 but cannot open our solution as there is one azure data factory project.
Does Azure Data Factory support on Visual Studio 2017?
I tweeted the Visual Studio team with exactly this issue a couple of days ago. I even included a screen shot very similar to yours.
This is the response I got:
@mrpaulandrew We have no info about it yet. Our team is already working on this. Please stay tuned to our blog: https://blogs.msdn.microsoft.com/visualstudio/.
So to answer your question. No, not at the moment.
But hopefully very soon.
Hope this helps.
