Omnisharp no longer runs on most of my projects

[smashedapples20]

Issue Description

I wish I could try to explain what's going on. OmniSharp is failing to run on most of my project, but I have at least one that it's still working on. I can't find any differences to explain why it runs on some but not on others. The log output doesn't give any hint (to me at least) that anything is even wrong.

The log on the projects that fail to load properly seems to end abruptly after "Adding project …" where the projects that load correctly go on to an "Update project" step.

Steps to Reproduce

Have projects with some package references to NuGet packages stored in an Azure DevOps feed.

One or more of the following:

• Upgrade to OmniSharp 1.19
• Update .Net Framework
• Have some of the tokens on Azure DevOps expire (if this is the problem, how do I update them for OmniSharp to be able to figure this out?)

Expected Behavior

Everything continues to work as normal

Actual Behavior

Seemingly arbitrary projects fail to have the OmniSharp features work

I'm doing more debugging...

There appears to be a problem with OmniSharp trying to load projects that have PackageReferences to packages in an Azure DevOps Artifacts feed. I've commented out all of the references to those projects, and things are loading properly now (with lots of red since all of my references are broken now).

[rchande]

@smashedapples20 OmniSharp expects your projects to be restored. I suspect that if you update your access tokens that this will resolve itself. However, if you want to get more informative logs, you can set the setting "omnisharp.loglevel" to "debug".

[smashedapples20]

@rchande Everything is restored. Both dotnet restore and nuget restore run fine... I'll try upping the verbosity of the logs.

[smashedapples20]

Upping to "debug" didn't change the log content.

[rchande]

@smashedapples20 Sorry, apparently the option is called omnisharp.loggingLevel. Mind trying again?

[smashedapples20]

I just found that... running now.

[smashedapples20]

I pared it down to a single project (not in a solution), and now I have the debug output

[filipw]

it could be that you are running into problem with wildcard package references / runtime versions?
try this solution #3009 (comment)

[smashedapples20]

@filipw You're a wizard! That was it... I got so focused on the fact that the references I was eliminating were Azure DevOps feeds instead of using wildcards.

Thank you for your help!
