Omnisharp-roslyn: Go to metadata doesn't work

[worming004]

Issue Description

When I press F12 on a type from an external library (imported from third party library or system like int), the message 'No definition found for {type}' instead of getting metadata informations in a new windows.

I don't have any issue pressing F12 on a class defined in current project.

Steps to Reproduce

In any method

• Write int value = 5;
• Press F12 on ìnt

Expected Behavior

Open a new tab with metada information

Actual Behavior

a tooltip is shown with 'No definition found for int' message

More informations. When my mouse in on type 'int', the summary is well shown

[filipw]

thanks - I will move this to omnisharp-roslyn, it's really a bug (regression) there

[filipw]

thanks for reporting - the PR with a fix is open https://github.com/OmniSharp/omnisharp-roslyn/pull/1625

[amarkezic]

Had the same problem. If you have mono installed on linux a temporary solution is to move xbuild location /usr/lib/mono/xbuild -> /usr/lib/mono/xbuild-backup (but makes it so you cant use xbuild).

Version 1.21.9 of Omnisharp fixed the problem for me.

[filipw]

yeah mono paths are no longer loaded for Mono < 6.4.0 in 1.21.9

[ImJaviPerez]

I have the same problem using last version.
Is it fixed?
