Plugin stopped working with upgrade to 2.0.x

[jvcdk]

Type: Bug

Issue Description

After upgrading to v2.0.357 the plugin stopped (more or less) working for me. It will look up symbols within a single file, but any lookup to other files fail.

A thought is that it may be related to the fact that my solution is located in the root folder of the workspace, but in a subfolder. Also, there are two solutions in the subfolder (fyi). However, trying to create a solution file in the workspace root did not remedy the issue.

Steps to Reproduce

For me: Open up any of my previous working workspaces. I don't know how to re-create the issue.

Creating a new workspace / project (with a .csproj file) remedies the issue.

Note: I am also using a Devcontainer setup.

Expected Behavior

C# Intellisense to be working.

Actual Behavior

C# Intellisense is not working in my existing workspaces.

@jvcdk So if you have two solution files, we wouldn't have known which one to pick; I think Omnisharp might have picked one arbitrarily or had you use the picker. In any case, if you invoke the Command Palette (Ctrl+Shift+P on Windows -- I admit I don't know what it is on Linux) you should be able to find a "open solution" command which will let you pick the one you want. You can also set dotnet.defaultSolution as a workspace setting to specify the one you want by default.

[jasonmalinowski]

And I've written up #6132 to be a bit friendlier in this case.

[jvcdk]

Then open solution worked perfectly :) I did look for it yesterday, I just did not find it. I was looking up "CSharp..." in the menu, and not ".Net". My bad.

Thank you for your quick reply :) And good idea with #6132 :)
