Solution explorer doesn't show source generated files

[virzak]

Describe the feature you'd like

With the following code:

using System.Text.RegularExpressions;

namespace SG;

public partial class Class1
{
    Regex r = MyRegex();

    bool Test(string s) => r.Match(s).Success;

    [GeneratedRegex("abc.*")]
    private static partial Regex MyRegex();
}

I can see the generated source in VS

However it is unavailable in VS Code

Alternatives considered

Use Visual Studio is one alternative.

Environment Information

Windows 11
VS Code 1.81.0
C# Dev Kit v0.4.2

This is a very useful functionality, and it is constantly being delayed :(

In VS this is provided through MEF APIs like IAttachedCollectionSource and IAttachedCollectionSourceProvider. These APIs do not exist and will not work in VSCode since we are in separate processes.

@lifengl is there a way for the C# extension to contribute to the solution explorer? Otherwise we may need a new brokered service for this kind of functionality.
