I am happy to say that I think it is fixed. When I upgraded to 15.6.4 the error occured much less frequently, but I did still have a couple of crashes. Since applying the fix posted by Emanuel I have not experienced a hang. I have probably only run 20-30 times, but so far, so good. I would be very interested in someone commenting on my post (herein) regarding when I break during the hang the "Tasty Flavored Project" shows up. This is not a project that I have on my drive. I don;t understand where it comes from.

Thank you for your feedback! A fix for this issue is now avaiable in Visual Studio 2017 version 15.7. If you are still experiencing this issue with the latest version please file a new report so we can investigate.

When I do Break-All it gives me this dialog. I don;t know what that project is. It is not mine, or part of my solution. I went ahead and did the dump. Attached.

I am also having the same problem. The IDE hangs randomly after an iOS build completes, but before the deploy. The wait cursor appears and the devenv window recomes unresponsive. I've attached two minidumps, one managed and one with native.

Also, in the debugger attached to the hung visual studio, you can see exceptions being thrown in a loop at a fast rate. (kernelbase)

Hi all,

We've been trying to reproduce this issue but unfortunately we couldn't do that. After looking into all the information (logs, dumps, etc.) provided by Dave we found what could be hanging VS on your end.

Since we cannot reproduce this issue we'd need you to verify a potential fix. You can download a Vsix that contains that fix from here, it should be installed on top of Visual Studio 15.6.4 with the Xamarin current stable bits installed.

Please, let us know if the hang is gone after installing the attached Vsix so we can include the fix in the next release.

If you want to rollback to the stable version you can do that from the Visual Studio Installer, it should appear as an individual component called 'Visual Studio Tools for Xamarin (Alpha)', like this:

Thanks!

Ema
