This is with Microsoft Visual Studio Community 2019, Version 16.6.4, VisualStudio.16.Release/16.6.4+30309.148, .NET Framework Version 4.8.03752
And Android 5.1 API 22. I'm debugging direct onto an Android Phone plugged into my PC over USB.
When I change code and do a build, or even a Rebuild. when I debug the program, it often does not deploy the code but runs the previous version. i have to explicitly do a Clean then Deploy and debug to get the newly compiled code.
