Event logs

Not much to say apart from the summary. DocSync is getting to the third step of merging the docs and then crashes. Attached are logs from Windows Event Viewer.

This occurred with XVS (cycle7/cf6aa4d).

I have checked this issue with C7 latest build: Xamarin.VisualStudio_4.1.0.496_0026d9aaa4328a536c3b00b67972525c8f1982dc and observed that the DocSync is getting to the third step of 'merging the docs' then docsync window crash. Third step doesn't show green.

According to the screencast of Comment #3, DocSync is working as expected. No crash is present, DocSync just finishes Step 3 and the process ends, making the system tray icon to disappear.

To verify that DocSync worked as expected, you could go to the Reference Assemblies folders (Program Files (x86)\Reference Assemblies\Microsoft\Framework\...) and check the Xamarin.iOS.xml or MonoTouch.xml files inside the corresponding v1.0 folder. If you see a version attribute in the root xml node (e.g: <doc version="">), then it means that DocSync has merged and copied the new documentation successfully. That tag version is added by DocSync as a mark for future update checks.

Also, the log that is useful with DocSync is the DocSync log. You can find it in %LOCALAPPDATA%\Xamarin\Logs\DocSync. There you can also check for errors and useful messages.

Re assigning and changing the state to NEEDINFO to let you verify and close properly.

Changing the state to RESOLVED / ANSWERED.

@Parmendra, please verify and reopen if needed.

Comment 7 Parmendra Kumar 2016-05-17 16:49:29 UTC
Thanks @Jose

I have seen that the DocSync successfully sync in (Program Files (x86)\Reference Assemblies\Microsoft\Framework\...).

Hence closing this issue.
