C code and TS code lgtm.

I'd like someone more familiar with the debug proxy to review that part

@radical @lambdageek Could you please do a final review so I can merge?

lambdageek

C and TypeScript lgtm. I tried to follow BrowserDebugProxy, but I'm not sure if I completely understand it

This is fine for now. But in a follow up we should change this to use these from runtime-extra-platforms-wasm.yml with a new debuggerTestsOnly parameter.

eng/pipelines/extra-platforms/runtime-extra-platforms-wasm.yml

src/mono/wasm/debugger/DebuggerTestSuite/Inspector.cs

                    notifications.Remove(what, out _);
                    return tcs.Task;
                }

                throw new Exception($"Invalid internal state, waiting for {what} while another wait is already setup");
            }
+            else if (nextNotifications.TryDequeue(out var notification))


What if the next notification in the queue is for a different string what?

I'll push some changes and it will be throwing an exception if it's a different string what

src/mono/wasm/debugger/DebuggerTestSuite/Inspector.cs

+                    await Client.SendCommand(sessionIdNewTarget, "Profiler.enable", null, token);
+                    await Client.SendCommand(sessionIdNewTarget, "Runtime.enable", null, token);
+                    await Client.SendCommand(sessionIdNewTarget, "Debugger.enable", null, token);
+                    await Client.SendCommand(sessionIdNewTarget, "Runtime.runIfWaitingForDebugger", null, token);
+                    await Client.SendCommand(sessionIdNewTarget, "Debugger.setAsyncCallStackDepth", JObject.FromObject(new { maxDepth = 32}), token);


For a follow up PR - the commands here, and in DebuggerTestBase.InitializeAsync should use the same base set of commands. And each case can add any additional ones as needed. Like the ones here seem to be the same.
