Description Brian Macomber 2017-07-28 13:19:30 UTC
Not sure when it hangs, but it only happens you launch from a solution shortcut, like the quick links when right clicking on the VS icon in the task bar.  If you open VS first and then the forms solution it opens correctly.

This does not happen with other solutions, only forms.

Hey @Brian! Thanks so much for taking the time to submit this report. Could you please attach a reproduction project and your IDE logs (found by going to Help -> Xamarin -> Zip Logs)?

I'm unable to reproduce this issue using the latest Visual Studio 2017 15.3 preview builds.

Logs attached, I'll see if a simple project causes the issue.  This did just show up with one of the last updates to VS, it previously did not cause a problem.

The same project causes an issue on both of my dev machines.  I would be fine providing you the actual production product causing the issue if there is a private way I could share it.
Comment 4 Prashant [MSFT] 2017-08-01 08:26:31 UTC

Are you able to reproduce this with a small/new project? If you still stuck, I have emailed you the link to upload the project
Comment 5 Brian Macomber 2017-08-01 13:37:26 UTC
A small project seemed to be ok.  I think it may be an startup issue with Resharper, though I thought I had tried this in the past, I disabled Resharper and the project opened fine.  And it was fine enabling resharper after start up.  I wonder if there is deadlock or something happening between the two.

I'm uploading the solution that is causing the issue.  It doesn't have everything needed to compile, but it probably would cause the same deadlock issue with Resharper.  I'll keep playing on my end also.  It's not a major deal, it works as you as you don't start VS from the .sln file, just open VS first, then open the project.

Comment 6 Pierce Boggan [MSFT] 2017-08-01 15:16:14 UTC
Awesome! If you hit this issue again, please go to Help -> Report a Problem within Visual Studio, and it will automatically upload some diagnostic reports about what went wrong, which is super helpful for debugging crashes.

Based on the information provided, this seems to be an issue with ReSharper and I would recommend raising it with the JetBrains team.

Thanks again for reporting this issue! :)

FYI, this issue resolved for me today with a VS update to 15.3.1
