C# Winform freezing on SerialPort.Close

Question

I have a winform program that does some asynchronous IO on a SerialPort. However, I\'m periodically running into an issue with the program freezing on the SerialPo

Answer 1

I had a same problem. I solved this problem by using SerialPortStrem library. You can install by Nuget Pageckage Installer.

SerialportStream libary has the following advantages.

• An independent implementation of System.IO.Ports.SerialPort and SerialStream for better reliability and maintainability.

After using SerialPortStream library, I hadn't UI freezing problem such as deadlock in WPF. I think the same issue in Windows forms. so, use the SerialPortStream library.

This library is obviously a solution to solve the UI Freezing.
