📝 Walkthrough

Walkthrough

A conditional check was added to the UpdateActionAsync method in MainViewModel.cs. This check clears the Results collection when both a cancellation is requested and a specific flag is set, allowing for more precise control over result clearing during asynchronous operations.

Poem

A hop, a skip, a cancellation call,
Now results are cleared, not left to sprawl.
With flags and checks, the code is neat,
Async bunnies never miss a beat.
So here’s to changes, swift and bright—
The launcher’s future’s looking right! 🐇✨

217-217: Replace placeholder text in debug message.

The debug message contains "BLAH-" which appears to be placeholder text. Please update it with a more descriptive message.

Apply this diff to improve the debug message:

-                            App.API.LogDebug(ClassName, "BLAH- Token cancelled but results marked to clear");
+                            App.API.LogDebug(ClassName, "Token cancelled and results marked to clear - clearing existing results");

215-219: Logic implementation looks good!

The conditional check correctly handles clearing results when both cancellation is requested and the shouldClearExistingResults flag is set. This provides the granular control needed for managing results during cancellation scenarios.
