Description Ruben Buniatyan 2017-11-02 17:01:53 UTC
# Steps to reproduce
No specific steps.
I'm starting regret my investments in Xamarin. The IDE and build tools are way too buggy and unstable. And each update is a pain. Runtime is pretty good though.

# Expected behavior
To allow code in general. To allow type, scroll, and build without crashing every minute or so.

# Actual behavior
IDE just hangs and crashes during coding or scrolling the .cs files.

# Supplemental info (logs, images, videos)
After crash, Visual Studio suggests:
"A previous session terminated unexpectedly. Disabling extension Xamarin for Visual Studio might help prevent similar issues."

# Test environment (full version information)

Hi Ruben,

I apologize in advance if this has been causing you stress. I'd like to offer help in diagnosing this issue so we can figure out what's going on here.

If you can follow a few steps, this will help me identify why your Visual Studio is hanging. Please attempt step 1 when Visual Studio is hanging and steps 2 or 3 prior to the next time Visual Studio is hanging:

1. https://developer.xamarin.com/guides/cross-platform/windows/visual-studio/troubleshooting/vs-callstack/

2. Install the following extension: https://marketplace.visualstudio.com/items?itemName=VisualStudioProductTeam.ProjectSystemTools

The next time this occurs, look at the View->Other Windows->Build Logging which will have design time builds that might be deadlocking/failing.

3. If #2 does not work well for you, follow these instructions to enable Design Time Build Logging

(Ensure you are following the Visual Studio 2015 instructions as we do not support the new project system yet)


The more information you can provide, the better we can identify the cause of this issue. Also if you have a reproduction project that you can reproduce this behavior with, please upload it to this bug report.

Thank you for the report!

Not sure what to do with steps #2 and #3. I installed the extension but I can't do anything while VS is hung. The second instance of VS has empty Build Logging while dumping the first's process. Seems I missed something.
