Developed an abortable TCPing test feature for the SpeedtestService in the 2dust/v2rayN repository, enabling users to cancel ongoing network tests by pressing ESC. This enhancement was implemented using C#, .NET, and asynchronous programming techniques to monitor for user input and gracefully interrupt long-running test sequences. The solution addressed a previous limitation where network measurements could stall the user interface, improving overall responsiveness and user control during speed tests. All changes were localized to the repository, ensuring streamlined integration with existing workflows and facilitating easier release management and quality assurance for future updates to the network measurement functionality.
