Visual Studio 2019 crashes during serial debugging

Print Post  
Hello,
i installed the development chain yesterday and am playing around / testing the IDE / serial debugging with a Teensy 4.0.
Current system configuration is:

Microsoft Visual Studio Community 2019
Version 16.4.2
VisualStudio.16.Release/16.4.2+29613.14
Microsoft .NET Framework
Version 4.8.03752

Installierte Version: Community


Arduino IDE for Visual Studio by Visual Micro   19.0
Visual Micro is an Arduino Compatible IDE for Visual Studio 2015-2019. For more information and forum please visit www.visualmicro.com.

...

For testing I´m using the BlinkwithoutDelay project mentioned in the tutorial.
Sketch compilis without errrors, Teensy is running / LED blinking and sends debug data to serial port as intended.

Everytime I´m trying to change a debbugger breakpoint (changing the existing or adding a new breakpoint) the Visual Studio IDE crashes and restarts. Any hints how to avoid this?

Thanks for the info. This sounds like it might be a VS issue but I am unclear if debugging is running or not when you try to add/remove/modify breakpoints?

Close the serial window to be sure the serial debugger is not running. (Although I would not expect that to cause a crash but am asking anyway)

Hi Tim,
I tried both (with debugger running and stopped). Same result (crashes) Sad. 
I have a older Visual Studio Installation (2013) installed (not running) parallel for Twincat Development (Beckhoff). Can this be part of the problem?

No the IDE's are unconnected. It's a vs 2019 bug and I think was also present sometimes in VS2017.

Close the solution then delete the ".vs" folder from below the solution folder. Then re-open the solution.

Does this resolve?
