Yosemite OSX, mono 4.0.1

[chrisdias]

i forgot i had this in my .bash_profile and it seems to fix the problem.

export MONO_MANAGED_WATCHER=disabled

@sayedihashimi this needs to be documented on the asp.net site

[spboyer]

added to bash_profile.

Adding @davidfowl @glennc @danroth27

Do you guys know of any fix/workaround?

[spboyer]

Latest dnvm install this is still an issue.

$ dnvm list

The web template runs under 1.0.0-beta4, #140 is still valid on dnu build, be sure that you are setting the dnvm to default

@chrisdias Just encountered this. Your suggestion nearly worked for me but I had to use export MONO_MANAGED_WATCHER=false not export MONO_MANAGED_WATCHER=disabled.

[geirsagberg]

Had the same problem, export MONO_MANAGED_WATCHER=false fixed it for me as well.

[jrock2004]

With false will it detect change or do you still need to restart after every change?

[geirsagberg]

It would seem changes are not detected, unfortunately, so this is hardly a permanent solution.

[johnpapa]

export MONO_MANAGED_WATCHER=false fixes it for now, but I agree that the watcher should detect changes long term

[johnpapa]

any update on this @sayedihashimi or guidance?

[scionwest]

Using export MONO_MANAGED_WATCHER=false didn't solve the issue for me. Are there other work-arounds for this issue?
