Visual Studio 2019 hangs on build & debug Xamarin project

Piotrek Brzezin 1

Hi,
I'm experiencing some strange problem with visual studio 2019, it hangs when i build & debug android project.
I have to close VS and delere all obj/bin folders and restart VS than start debugging again.
The same situation is with archiving.
Does somebody saw such behavior?

Hi, PiotrekBrzezin-9255. To fix the VS hang problem, try the following tips:

Do you debug the project on an emulator? Please make sure you've enabled the hardware acceleration on your pc. You could refer to this doc: https://learn.microsoft.com/en-us/xamarin/android/get-started/installation/android-emulator/hardware-acceleration?pivots=windows

What's the version of VS on your pc? Try to update it to the lastest stable version and test again. Or open VS installer to repair the VS.

Restart the adb server: open Tools -> Android -> Restart Adb Server

I have checked all of your suggestions.
I using x86 emulator image, Hyper-V is installed on windows.
I tested on VS 2019 latest, and VS2022 pre.
Restarting adb server when problem happens not helps.
The only way is to close VS, delete bin/obj, and restart VS again and compile project and start debug or create archive.

But I think there is two problems, one with start debugging on emulator, and another when kompilation freezes during create adnroid archive.

Hi, PiotrekBrzezin-9255. Will the problem occur on a new created project? And try to uninstall the VS and reinstall it to deploy the project. If both doesn't work, this may a potential issue with VS and it's sugggested to report the issue to the VS product team via Visual Studio's "Report a Problem" menu and then follow them on the developer community site.
