Description

Breakpoints do not work properly in secondary threads (those created explicitly or from threadpools). In Visual Studio Code, C# projects, execution does indeed pause on breakpoints but the IDE is not notified that it's stopped on a breakpoint. So you can neither move past the breakpoint nor check watches.

Research direction

Start by reproducing the breakpoint behavior in Visual Studio Code with a C# project that uses an explicitly created or threadpool secondary thread. Done means the IDE is notified when execution pauses, allowing the user to continue past the breakpoint and inspect watches.
