3

After upgrading to Update 3 I'm now seeing the following error when launching into Debug n a WebAPI solution. The debug starts fine but I would like to get rid of the error.

The error messagebox reads:

Internal Diagnostics Hub Exception. See log for more details.

So I enabled logging by adding these registry keys:

HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\14.0\DiagnosticsHub\LogLevel  
HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\14.0\DiagnosticsHub\LogDirectory

See this answer for more details on these keys.

The error I see in the logs is:

System.ArgumentException: Manifest file 'C:\Users\\AppData\Local\assembly\dl3\NGZ8Y6KN.6LD\A7OEKLH4.L4D\1b2ef2ef\00d85bfc_f9cad101\WebViews\PerformanceDebuggerSwimLanesView.manifest.json' not found.

When I check the location where this file is supposed to be:

C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\CommonExtensions\Platform\DiagnosticsHub\WebViews

I can clearly see the file it says it cannot find. I'm presuming that the location in the error message would/should be a copy of this "master" file in the VS webviews directory.

Anyone know how I might go about fixing this?

  • Did you get this resolved? I have same problem but no solution. This is happening for only certain solution – HaBo Dec 03 '16 at 18:52

    Yeah, I just disabled the diagnostics in VS since I wasn't using it anyway. – Jammer Dec 03 '16 at 23:30

    I installed typescript for 2015 and that resolved the problem. – HaBo Dec 04 '16 at 08:00
  • Installing Typescript works for me too, I think its reconstructing the MEF graph after installation that updated missing references. – Biniam Eyakem May 15 '17 at 10:11
