The first step is to create a new Xamarin.Forms project. Open Visual Studio 2019 and go to File | New | Project:
This will open the Create a new project wizard. In the top-middle section of the wizard, there is a search field. Type in xamarin and select the Mobile App (Xamarin.Forms) item from the list:
Complete the next page of the wizard by naming your project, and then click Create. Make sure you name the project DoToo to avoid any namespace issues:
The next step is to select a project template and a code-sharing strategy to use. Select Blank to create a bare Xamarin.Forms app. In versions of Visual Studio earlier than 2019, you will also need to change the Code Sharing Strategy option to .NET Standard. In the 2019 version, the blank Xamarin.Forms template app will create a .NET Standard library for you and you will not have the choice to select a shared project. Finalize the setup by clicking OK and wait for Visual Studio to create the necessary projects:
Congratulations! We've just created our first Xamarin.Forms app.
