I'm getting this same issue. I've worked around it by setting "omnisharp.useGlobalMono": "always" and installing Mono via homebrew.

i only update mono the problem have sloved,but "omnisharp.useGlobalMono" still is default!

True, I just removed my setting and it's still working.

Downgrade to ver 1.21.9 can prevent the problem temporary...

filipw · 2020-02-04T05:51:55Z

@JoeRobich would you mind looking into this? looks like it's related to OmniSharp/omnisharp-roslyn#1679 - thanks!

JoeRobich · 2020-02-04T06:36:01Z

Looks like it was caused by this Mono issue - mono/mono#18531.

6.6.0.161 which is what we packaged seems to be the last 6.6.0 build. We need to revert back to 6.4.0 or bump to 6.8.0.

filipw · 2020-02-04T06:46:06Z

ouch. I reckon we could bump the bundled runtime to 6.8.0 that's also stable already.

filipw · 2020-02-04T12:35:50Z

The current workaround - if you are affected - would be to one of the following:

downgrade back to 1.21.9
install Mono 6.6.0

I would personally recommend the latter since the MSBuild behavior with global Mono install on your machine would be better.

steveoh · 2020-02-04T15:10:41Z

Looks like i need a mono upgrade...

update

6.6.0 has omnisharp loaded and working. Thanks for the details and work around.

Would you like me to close the issue or do you want to close it when 6.8.0 is functioning?

filipw · 2020-02-04T19:16:19Z

I think it should stay open until we patch this

tverboon · 2020-02-05T06:48:33Z

What is the reason mono is being used and not .Net Core?

filipw · 2020-02-05T07:04:33Z

not all MSBuild tasks would work on .NET Core which would impact non-.NET Core projects.

steveoh · 2020-02-10T19:35:37Z

@filipw am I safe to install mono from homebrew and have it stay current now?

Bio-Tvorogok · 2020-08-28T20:05:35Z

I'm getting this same issue. I've worked around it by setting "omnisharp.useGlobalMono": "always" and installing Mono via homebrew.

God, man, you're my savior, I almost got to the point of removing the system))

brnhensley · 2021-07-20T22:14:51Z

I was having the same issue for a few months now and my problem was solved by changing "omnisharp.waitForDebugger": true to false. I'm not sure what the original cause was but finally the omnisharp server stopped timing out.

This solved my problem, thank you!

steveoh · 2022-04-12T15:40:37Z

isn't there a dotnet core implementation now that does not need mono at all?

JoeRobich · 2022-04-12T15:49:44Z

Mono and MSBuild are no longer included with nightly builds of O#. See the announcement at #5120
