Issue description

When using the custom signal syntax for C# described in the docs, the signal name is marked as a compiler error CS0117 "'Node.SignalName' does not contain a definition for 'MyCustomSignal'" despite compiling successfully in the editor.

Steps to reproduce

1. Create a C# script containing a custom signal.
2. Observe the compiler error.

using Godot;

public partial class GlobalSignals : Node
{
  [Signal] public delegate void SetCameraTargetEventHandler(Node3D target);

  public void EmitSetCameraTargetSignal(Node3D target)
  {
    EmitSignal(SignalName.SetCameraTarget, target);
  }
}

This extension only deal with GDScripts. The errors are coming from the C# extension, I'm afraid. I remember there's an option in Godot's tools menu to fix this, but I forgot how to do it.

Indeed it does. I had issues with syntax highlighting in Godot 3 that seemed to be resolved after I installed this extension. However, I can confirm syntax highlighting is still present after disabling this extension while using Godot 4. My mistake for attributing this issue to godot-tools. Thank you for the help, I'll look around for the option you mentioned.
