---Additional Info---
The symptoms appear very similar to a recent bug several customers have reported where Visual Studio is locking up while debugging an iOS project. I did a sanity check on the issue and was able to reproduce a very similar freezing behavior to what this customer describes for Android in one of my iOS tests, but only the first time I tested the app; when I tried again it worked as expected. 

I didn't observe the same behavior in my Android tests, but while I haven't been able to reproduce this precise issue on my end it still seems like something unusual is going on with the number of reports recently of Visual Studio freezing while debugging; and I'll add the similar sounding bug reports for iOS in Visual Studio in the "See Also" section shortly.

Also adding the logs from the customer.

Got the same issue. Previously had on VS2013 Update 3 (i've upgraded to Update 4 thinking this will help). Issue started ater installing latest (for today) update.

Occures on both - with fast deployment and without fast deployment. also 'use shared runtime' is checked. with fast deployment it's rarely, without - every time/

starting to get this issue with enabled fast deployment more often...
Comment 6 Joaquin Jares 2015-01-14 19:25:29 UTC
Is this bug related to fastdev (per your repro) or it does happen in any configuration? We do have a known issue with fastdev.
Comment 7 Eugene 2015-01-14 19:30:40 UTC
With both. If you need logs just send me steps where I can get them
Comment 8 Joaquin Jares 2015-01-14 19:33:46 UTC
It looks like we have a proper repro internally, so I can work on that for the time being. I'll keep the bug updated in case we need any more info. I expect to have an update tomorrow or friday at the latest.

This bugs primarily presents itself: 
When hitting a breakpoint
When continuing from a breakpoint


We have seen this bug showed 2 out of 7 test runs. This is especially present when there high RAM usage and multiple Visual Studio instances are running.

Test Case:
1 - Create a new OpenGL App (Android) Project Template
2 - Set a break point on line 75 in GLView1.cs             GL.LoadIdentity();
3 - Debug and you'll see the Visual Studio is Busy message

Comment 19 Ryan 2015-01-16 18:12:34 UTC
I do not have Resharper installed and am seeing this issue.
Comment 20 Joaquin Jares 2015-01-16 20:10:55 UTC
I will test with resharper to see if I can get to the repro faster, keeping Ryan's comment in mind. I understand it's way more prevalent with resharper installed. Not blaming it, just wanting to get to the most dependable repro I can find.
Comment 21 Eugene 2015-01-16 20:25:17 UTC
My resharper is 8.2.1. But yes, solution is big (especially core project, we have a complex data layer with a lot of classes) and sometimes i got my android app crashed or freezed (btw, i have not seen freezes after update) while debugging because of something with opengl. My workflow to reproduce was next: 
- working till first vs freeze
- kill devenv, start again (~20 minutes)
- next crash came quicker than previous (5..10 minutes)
- after 2 or 3 restart of vs i got freeze on every app launch
- toggle fast deployment switch and everything starts from beginning
Comment 22 Gerry Hall 2015-01-16 20:31:08 UTC
Also using ReSharper 8.2 here. Very large solution with a large PCL core, several unit test projects, Droid and iOS projects with their respective unit tests. 

I also have no issue with the first launch, it's always subsequent launches. However, once it gets into the frozen state it was on every launch.

I can also confirm that I rolled back to the MSI that Kent provided above and am no longer experiencing the issue.
Comment 23 Paul Roy 2015-01-17 18:39:02 UTC
I am experiencing this issue without Resharper too, with a Visual Studio 2013 Community Edition. My solution is of medium size, with a few projects, iOS / Android + PCL, a few nuget packages, and no components at all.

The bug seems to happen most of the times when I use ZXing (https://www.nuget.org/packages/ZXing.Net/) and even when I'm not going to hit any breakpoint.
Comment 24 Ian Ceicys 2015-01-19 13:35:53 UTC
I had a GoToMeeting with Paul and we installed the hotfix build (Xamarin.VisualStudio_3.9.272.msi) and Paul saw the Android hang issue being resolved. We are waiting on an additional build on the 3.9 lane that will contain the iOS related fixes. 

The service release will include the fix for this issue.
Comment 25 Adam Kapos 2015-01-20 08:01:33 UTC
I'm having a similar problem running 3.9.236. On a certain device Visual Studio hangs when I start debugging (when the debugger tries to connect). The deployed app hangs at the splash screen too. Even when I launch it from the phone. I have ReSharper.
Comment 26 Jose Gallardo 2015-01-20 08:16:49 UTC
This issue is fixed on XVS 3.9.274. (Not yet public)
Please verify.

Thanks
Comment 27 Adam Kapos 2015-01-20 08:19:26 UTC
Can you provide it to me so I can check?
Comment 28 Ian Ceicys 2015-01-20 08:31:15 UTC
Build (3.9.274) has been resolved the issue with android hangs and has been successfully installed by several customers. 

At this time we have the private build available and I've reached out to additional customers who are/were facing this issue and provided this hotfix build as necessary.
Comment 29 Adam Kapos 2015-01-20 08:42:37 UTC
This and disabling fast deployment solved it for me.
Comment 30 Ian Ceicys 2015-01-22 12:19:22 UTC
In looking into folks having to disable fast deployment for build 274 to work...we've looked into the issue and we believe that customers should ensure when deploying to emulators that the emulators have an SD Card includeded in the configuration of the virtual device. Fast Dev requires the use of the SD Card for deployments.
Comment 31 Adam Kapos 2015-01-22 12:21:17 UTC
I had troubles with a Prestigio 7500. I think it was the only device we tested without expandable storage (other devices had SD slots, but they were empty).
Comment 32 Sami Chamoun 2015-02-04 01:56:58 UTC
I am experiencing this issue since updating to 3.9. I do not have ReSharper.

Is there a timeframe for a resolution on this?
Comment 33 David Brillon 2015-02-05 08:38:00 UTC
I am experiencing the same problem with 3.9.236.0 (2 of my colleagues also have the problem).  
I don't have Resharper.  
Visual Studio will freeze 1 out 4 times I try to debug.
I also tried to uncheck "Use Fast Deployment (debug mode only) without success.    

How can we get the hotfix?
Comment 34 Kent Green [MSFT] 2015-02-05 11:50:10 UTC
Per comment 32 & comment 33: The fix is currently available in the Alpha release channel, as Xamarin 3.9.289.0.

I get this issue also and I do not have ReSharper installed. Xamarin Studio debugs just fine. Is this verified fixed back in the day or should there be a new bug created?
Comment 37 Brendan Zagaeski (Xamarin Team, assistant) 2015-12-09 17:57:04 UTC
@Joakim and @William,

This bug has been marked fixed since January, so hangs observed in recent versions of Visual Studio are unlikely to be related to this old report. See Bug 36185 for one example of a more recent cause of hangs. That bug report also includes some hints on additional information to collect and file in new bug reports to help diagnose specific causes of hangs.
