This is an easier alternative to hide the vshub traffic.
Go to Tools > Fiddler Options > Connections tab and add http://localhost:49155
to the bypass list. This will skip all traffic posted to that URL.
*Edit: Fiddler may need to be restarted after adding to the bypass list.
For me, the fix to stop "spamming" to Fiddler4, instead of a Fiddler filter, which I could have chosen to do, was to change a Visual Studio 2015 option:
Visual Studio 2015 -> Tools -> Options -> Debugging -> General -> uncheck/disable "Enable Diagnostic Tools while debugging"
VSHUB.exe service must be the service that assists Diagnostic tools while debugging and is continously pinging your website/webapi/web app you are debugging. I do not need debugging. Diagnostic tools at this time so I just disabled it in Visual Studio
In regards to disabling VSHUB.exe, I was tempted to do that, until I read from someone at Microsoft, its best to not disable it for a better Visual Studio 2015 experience and they add new features to Visual Studio that utilize VSHUB.exe over time:
