Emulator stop working on Visual 2019 PLEASE HELP ME!

sadddsadsasadddsadsa USMember ✭✭

Suddenly the iOS emulator has stopped working in Visual 2019:

I had installed Visual 2017 and 2019 at same time and in both I worked without problems.

Then I did these two things and I do not know if any really influenced or none did and it is for another reason:

· I uninstalled Visual 2017
· I activated the connection of the iPhone to the MAC via wifi

I have tried everything to solve it:
· Reinstall visual 2019
· Reinstall Xamarin's tools on the MAC
· Disable the WIFI connection with the iPhone
· Uncheck simulator to windows

AND NOTHING has worked, I'm desperate.

The error is as follows:

  • If I have connected the iPhone (no matter if it is via wifi or cable) and in the drop-down I select an emulator, when run they ignores it and always compiles for iPhone.

  • If I do not have any iPhone connected, immediately after clicking on the play button that says: "Please select a valid device before running the application.".

The emulator works well in the mac and in the XCode but not from the Visual. I have the latest version of everything.

Please I need help.

    Did you try running Visual Studio for Mac? Can it see the simulators?

    I didnt have VS in Mac, only Xamarin.iOS.

    My problem is different of all I’ve readed on the internet because I see all the emulators on the dropdown but when y compile for one it ignores me or show the message “Please select a valid device..”
