@yvef I pulled down the runtime repo and opened the runtime/src/libraries/System.Private.CoreLib/generators/ folder in Code. I do not see a project reference for a .shproj in the System.Private.CoreLib.Generators.csproj. Are you working off a particular branch or have you made local changes?

[JoeRobich]

Never mind my earlier question. I see now that you were opening the runtime/src/libraries/System.Private.CoreLib folder instead.

So shared projects are supported when you open a folder containing a .csproj that has a project reference to the .shproj. The reason for this is that shared projects are treated as a set of files to be added to C# project. The shared project itself doesn't contain a target framework or package dependencies necessary to generate a compilation. It only makes sense when included in a C# project which has framework and other dependencies.

[yvef]

@JoeRobich no, I have not local changes. It's main branch. I tried open System.Private.CoreLib and whole Libraries folders. and nothing. If I open Libraries I can choose only few project using "Omnisharp Select Project" command. A most of remaining is ignored and, of course, it didn't parsed.

[yvef]

@JoeRobich but what if I open whole Library folder. I have to choose a certain project but I cannot to do it. Most of them are missing, as I mentioned before.

[JoeRobich]

Ah, so the issue is that the C# extension does not show project files in the selector when solution files are discoved?

[yvef]

I think yes. Should I create a new issue?

[JoeRobich]

@yvef Opened #4644 to add .csproj files to project selector.
