I built a Xamarin simple app project for android device. It's compiled and also run on my device, whereas after some times I faced an error. the error is:
"This project needs to be migrated."
and also I couldn't create new android Xamarin project. In fact, it's disappeared from new project section. What can I do??
Forms. . NET Multi-platform App UI (MAUI) is a multi-platform technology for developing mobile (iOS and Android) and desktop (Windows and Mac) applications.
Open Visual Studio 2019 in your mac machine and see the left side top corner two options which are Open and New. You can click New option to create a new project and Open option to open an existing Xamarin project.
. NET Multi-platform App UI (MAUI) is called the "evolution of Xamarin. Forms" by Microsoft because it lets developers create desktop apps in addition to the traditional Xamarin mobile targets, iOS and Android.
My issue was that "Mobile development with .NET" was not selected/installed in the Visual Studio Installer for VS2019 (coulda sworn I selected that when I moved from 2017 to 2019, but whatever). Once selected and installed, the migration warnings disappeared and I could run the projects.
