vs crash screen shot

When VS is connected to the MAC agent and MAC agent suddenly becomes inaccessible (goes to sleep, restarts) VS crashes and sometimes the whole windows becomes unresponsive.

Comment 1 Farhad Adeli 2016-07-09 07:21:46 UTC
Microsoft Visual Studio Enterprise 2015
Version 14.0.25123.00 Update 2
Microsoft .NET Framework
Version 4.6.01055

My Enviroment:
VS running on PC Win8.1 with AMD CPU, started new project from templates.
MAC running on VMware Workstation 12 on laptop with Win8.1 and Corei5 CPU, xCode 7.3.1, xamarin.ios-9.8.1.4, xamarin.mac-2.8.1.4, XamarinStudio-6.0.1.8-0
PC is directly connected to laptop with LAN cable
VM network is running in bridged mod.

VS crashes when MAC is suspended or shuts down.

Hi Farhad, thanks for reaching out. If I am understanding things correctly, this is an unsupported configuration. Apple’s licensing terms require a physical Mac for iOS development. As such, I am closing this report.
Comment 3 Farhad Adeli 2016-07-15 05:44:56 UTC
It does not matter where my MAC is, and i am not reporting a bug for MAC. this is as the problem show is a un-handled  exception with Renci.SshNet library and has nothing to do with mac or my configuration. if you dont wana fix a bug just say it, don't make excuses ...
If you like just edit my comment about mac running on vm and we are good to go.

This is quite possibly a duplicate of Bug 41918.  If the original reporter concurs with that assessment he may mark it as a duplicate himself.

If the original reporter would instead be looking for additional investigation on this issue as a separate bug, the Xamarin team would (as a first step) be looking to get the complete stack trace of the NullReferenceException (from Event Viewer) in an environment where the Windows machine is connected to a physical Mac or a Mac OS running virtualized on a physical Mac to comply with Apple's terms of use.  Thanks in advance.

This issue should be already fixed in the latest release.
