[severity:It bothers me. A fix would be nice]
Microsoft Visual Studio Community 2019
Version 16.11.2
.NET version 4.8.04084
Visual Basic
Code snippet:
cboCOMPort.Items.Clear()
For Each COMString As String In My.Computer.Ports.SerialPortNames
cboCOMPort.Items.Add(COMString)
Next
ISSUE #1
SerialPort1.PortNames shows incorrect number of ports
Example:
Run VB app, shows COM3, COM4 and COM5
Disconnect COM4, still shows COM3, COM4 and COM5
ISSUE #2
SerialPort1.PortNames shows duplicate port names
Example:
Run VB app, shows COM3, COM4 and COM5
Disconnect COM4 , still shows COM3, COM4 and COM5
Add COM4 , now shows COM3, COM4, COM4 and COM5
When I compile for NET 3.5, I don't have these issues.
Please review and advise.
Thanks
Ken
