Create a Xamarin.Forms application quickstart

In this quickstart, you will learn how to:

• Create a Xamarin.Forms Shell application.
• Define the user interface for a page using eXtensible Application Markup Language (XAML), and interact with XAML elements from code.
• Describe the visual hierarchy of a Shell application by subclassing the Shell class.

The quickstart walks through how to create a cross-platform Xamarin.Forms Shell application, which enables you to enter a note and persist it to device storage. The final application is shown below:

Prerequisites

• Visual Studio 2019 (latest release), with the Mobile development with .NET workload installed.
• Knowledge of C#.
• (optional) A paired Mac to build the application on iOS.

For more information about these prerequisites, see Installing Xamarin. For information about connecting Visual Studio 2019 to a Mac build host, see Pair to Mac for Xamarin.iOS development.

Get started with Visual Studio 2019

1. Launch Visual Studio 2019, and in the start window click Create a new project to create a new project:

   

2. In the Create a new project window, select Mobile in the Project type drop-down, select the Mobile App (Xamarin.Forms) template, and click the Next button:

   

3. In the Configure your new project window, set the Project name to Notes, choose a suitable location for the project, and click the Create button:

   

   Important

   The C# and XAML snippets in this quickstart requires that the solution and project are both named Notes. Using a different name will result in build errors when you copy code from this quickstart into the project.

4. In the New Mobile App dialog, select the Tabbed template, and click the Create button:

   

   When the project has been created, close the GettingStarted.txt file.

   For more information about the .NET Standard library that gets created, see Anatomy of a Xamarin.Forms Shell application in the Xamarin.Forms Shell Quickstart Deep Dive.

5. In Solution Explorer, in the Notes project, delete the following folders (and their contents):

   • Models
   • Services
   • ViewModels
   • Views

6. In Solution Explorer, in the Notes project, delete GettingStarted.txt.

7. In Solution Explorer, in the Notes project, add a new folder named Views.

8. In Solution Explorer, in the Notes project, select the Views folder, right-click, and select Add > New Item.... In the Add New Item dialog, select Visual C# Items > Xamarin.Forms > Content Page, name the new file NotesPage, and click the Add button:

   

   This will add a new page named NotesPage to the Views folder. This page will be the main page in the application.

9. In Solution Explorer, in the Notes project, double-click NotesPage.xaml to open it:

   

10. In NotesPage.xaml, remove all of the template code and replace it with the following code:

    <?xml version="1.0" encoding="UTF-8"?>
    <ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
                 xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
                 x:Class="Notes.Views.NotesPage"
                 Title="Notes">
        <!-- Layout children vertically -->
        <StackLayout Margin="20">
            <Editor x:Name="editor"
                    Placeholder="Enter your note"
                    HeightRequest="100" />
            <!-- Layout children in two columns -->
            <Grid ColumnDefinitions="*,*">
                <Button Text="Save"
                        Clicked="OnSaveButtonClicked" />
                <Button Grid.Column="1"
                        Text="Delete"
                        Clicked="OnDeleteButtonClicked"/>
            </Grid>
        </StackLayout>
    </ContentPage>
    

    This code declaratively defines the user interface for the page, which consists of an Editor for text input, and two Button objects that direct the application to save or delete a file. The two Button objects are horizontally laid out in a Grid, with the Editor and Grid being vertically laid out in a StackLayout. For more information about creating the user interface, see User interface in the Xamarin.Forms Shell Quickstart Deep Dive.

    Save the changes to NotesPage.xaml by pressing CTRL+S.

11. In Solution Explorer, in the Notes project, double-click NotesPage.xaml.cs to open it:

    

12. In NotesPage.xaml.cs, remove all of the template code and replace it with the following code:

    using System;
    using System.IO;
    using Xamarin.Forms;
    
    namespace Notes.Views
    {
        public partial class NotesPage : ContentPage
        {
            string _fileName = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "notes.txt");
    
            public NotesPage()
            {
                InitializeComponent();
    
                // Read the file.
                if (File.Exists(_fileName))
                {
                    editor.Text = File.ReadAllText(_fileName);
                }
            }
    
            void OnSaveButtonClicked(object sender, EventArgs e)
            {
                // Save the file.
                File.WriteAllText(_fileName, editor.Text);
            }
    
            void OnDeleteButtonClicked(object sender, EventArgs e)
            {
                // Delete the file.
                if (File.Exists(_fileName))
                {
                    File.Delete(_fileName);
                }
                editor.Text = string.Empty;
            }
        }
    }
    

    This code defines a _fileName field, which references a file named notes.txt that will store note data in the local application data folder for the application. When the page constructor is executed the file is read, if it exists, and displayed in the Editor. When the Save Button is pressed the OnSaveButtonClicked event handler is executed, which saves the content of the Editor to the file. When the Delete Button is pressed the OnDeleteButtonClicked event handler is executed, which deletes the file, provided that it exists, and removes any text from the Editor. For more information about user interaction, see Responding to user interaction in the Xamarin.Forms Shell Quickstart Deep Dive.

    Save the changes to NotesPage.xaml.cs by pressing CTRL+S.

13. In Solution Explorer, in the Notes project, select the Views folder, right-click, and select Add > New Item.... In the Add New Item dialog, select Visual C# Items > Xamarin.Forms > Content Page, name the new file AboutPage, and click the Add button:

    

    This will add a new page named AboutPage to the Views folder.

14. In Solution Explorer, in the Notes project, double-click AboutPage.xaml to open it:

    

15. In AboutPage.xaml, remove all of the template code and replace it with the following code:

    <?xml version="1.0" encoding="UTF-8"?>
    <ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
                 xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
                 x:Class="Notes.Views.AboutPage"
                 Title="About">
        <!-- Layout children in two rows -->
        <Grid RowDefinitions="Auto,*">
            <Image Source="xamarin_logo.png"
                   BackgroundColor="{OnPlatform iOS=LightSlateGray, Android=#2196F3}"
                   VerticalOptions="Center"
                   HeightRequest="64" />
            <!-- Layout children vertically -->
            <StackLayout Grid.Row="1"
                         Margin="20"
                         Spacing="20">
                <Label FontSize="22">
                    <Label.FormattedText>
                        <FormattedString>
                            <FormattedString.Spans>
                                <Span Text="Notes"
                                      FontAttributes="Bold"
                                      FontSize="22" />
                                <Span Text=" v1.0" />
                            </FormattedString.Spans>
                        </FormattedString>
                    </Label.FormattedText>
                </Label>
                <Label Text="This app is written in XAML and C# with the Xamarin Platform." />
                <Button Text="Learn more"
                        Clicked="OnButtonClicked" />
            </StackLayout>
        </Grid>
    </ContentPage>
    

    This code declaratively defines the user interface for the page, which consists of an Image, two Label objects that display text, and a Button. The two Label objects and Button are vertically laid out in a StackLayout, with the Image and StackLayout being vertically laid out in a Grid. For more information about creating the user interface, see User interface in the Xamarin.Forms Shell Quickstart Deep Dive.

16. In Solution Explorer, in the Notes project, double-click AboutPage.xaml.cs to open it:

    

17. In AboutPage.xaml.cs, remove all of the template code and replace it with the following code:

    using System;
    using Xamarin.Essentials;
    using Xamarin.Forms;
    
    namespace Notes.Views
    {
        public partial class AboutPage : ContentPage
        {
            public AboutPage()
            {
                InitializeComponent();
            }
    
            async void OnButtonClicked(object sender, EventArgs e)
            {
                // Launch the specified URL in the system browser.
                await Launcher.OpenAsync("https://aka.ms/xamarin-quickstart");
            }
        }
    }
    

    This code defines the OnButtonClicked event handler, which is executed when the Learn more Button is pressed. When the button is pressed, a web browser is launched and the page represented by the URI argument to the OpenAsync method is displayed. For more information about user interaction, see Responding to user interaction in the Xamarin.Forms Shell Quickstart Deep Dive.

    Save the changes to AboutPage.xaml.cs by pressing CTRL+S.

18. In Solution Explorer, in the Notes project, double-click AppShell.xaml to open it:

    

19. In AppShell.xaml, remove all of the template code and replace it with the following code:

    <?xml version="1.0" encoding="UTF-8"?>
    <Shell xmlns="http://xamarin.com/schemas/2014/forms"
           xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
           xmlns:views="clr-namespace:Notes.Views"
           x:Class="Notes.AppShell">
        <!-- Display a bottom tab bar containing two tabs -->   
        <TabBar>
            <ShellContent Title="Notes"
                          Icon="icon_feed.png"
                          ContentTemplate="{DataTemplate views:NotesPage}" />
            <ShellContent Title="About"
                          Icon="icon_about.png"
                          ContentTemplate="{DataTemplate views:AboutPage}" />
        </TabBar>
    </Shell>
    

    This code declaratively defines the visual hierarchy of the application, which consists of a TabBar containing two ShellContent objects. These objects don't represent any user interface elements, but rather the organization of the application's visual hierarchy. Shell will take these objects and produce the user interface for the content.

                <Label FontSize="22">
                    <Label.FormattedText>
                        <FormattedString>
                            <FormattedString.Spans>
                                <Span Text="Notes"
                                      FontAttributes="Bold"
                                      FontSize="22" />
                                <Span Text=" v1.0" />
                            </FormattedString.Spans>
                        </FormattedString>
                    </Label.FormattedText>
                </Label>
                <Label Text="This app is written in XAML and C# with the Xamarin Platform." />
                <Button Text="Learn more"
                        Clicked="OnButtonClicked" />
            </StackLayout>
        </Grid>
    </ContentPage>
    

    This code declaratively defines the user interface for the page, which consists of an Image, two Label objects that display text, and a Button. The two Label objects and Button are vertically laid out in a StackLayout, with the Image and StackLayout being vertically laid out in a Grid. For more information about creating the user interface, see User interface in the Xamarin.Forms Shell Quickstart Deep Dive.

    Save the changes to AboutPage.xaml by choosing File > Save (or by pressing ⌘ + S).

16. In the Solution Pad, in the Notes project, double-click AboutPage.xaml.cs to open it:

    

17. In AboutPage.xaml.cs, remove all of the template code and replace it with the following code:

    using System;
    using Xamarin.Essentials;
    using Xamarin.Forms;
    
    namespace Notes.Views
    {
        public partial class AboutPage : ContentPage
        {
            public AboutPage()
            {
                InitializeComponent();
            }
    
            async void OnButtonClicked(object sender, EventArgs e)
            {
                // Launch the specified URL in the system browser.
                await Launcher.OpenAsync("https://aka.ms/xamarin-quickstart");
            }
        }
    }
    

    This code defines the OnButtonClicked event handler, which is executed when the Learn more Button is pressed. When the button is pressed, a web browser is launched and the page represented by the URI argument to the OpenAsync method is displayed. For more information about user interaction, see Responding to user interaction in the Xamarin.Forms Shell Quickstart Deep Dive.

    Save the changes to AboutPage.xaml.cs by choosing File > Save (or by pressing ⌘ + S).

18. In the Solution Pad, in the Notes project, double-click AppShell.xaml to open it:

    

19. In AppShell.xaml, remove all of the template code and replace it with the following code:

    <?xml version="1.0" encoding="UTF-8"?>
    <Shell xmlns="http://xamarin.com/schemas/2014/forms"
           xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
           xmlns:views="clr-namespace:Notes.Views"
           x:Class="Notes.AppShell">
        <!-- Display a bottom tab bar containing two tabs -->
        <TabBar>
            <ShellContent Title="Notes"
                          Icon="icon_feed.png"
                          ContentTemplate="{DataTemplate views:NotesPage}" />
            <ShellContent Title="About"
                          Icon="icon_about.png"
                          ContentTemplate="{DataTemplate views:AboutPage}" />
        </TabBar>
    </Shell>
    

    This code declaratively defines the visual hierarchy of the application, which consists of a TabBar containing two ShellContent objects. These objects don't represent any user interface elements, but rather the organization of the application's visual hierarchy. Shell will take these objects and produce the user interface for the content. For more information about creating the user interface, see User interface in the Xamarin.Forms Shell Quickstart Deep Dive.

    Save the changes to AppShell.xaml by choosing File > Save (or by pressing ⌘ + S).

20. In the Solution Pad, in the Notes project, expand AppShell.xaml, and double-click AppShell.xaml.cs to open it:

    

21. In AppShell.xaml.cs, remove all of the template code and replace it with the following code:

    using Xamarin.Forms;
    
    namespace Notes
    {
        public partial class AppShell : Shell
        {
            public AppShell()
            {
                InitializeComponent();
            }
        }
    }
    

    Save the changes to AppShell.xaml.cs by choosing File > Save (or by pressing ⌘ + S).

22. In the Solution Pad, in the Notes project, double-click App.xaml to open it:

    

23. In App.xaml, remove all of the template code and replace it with the following code:

    <?xml version="1.0" encoding="utf-8" ?>
    <Application xmlns="http://xamarin.com/schemas/2014/forms"
                 xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
                 x:Class="Notes.App">
    
    </Application>
    

    This code declaratively defines an App class, which is responsible for instantiating the application.

    Save the changes to App.xaml by choosing File > Save (or by pressing ⌘ + S).

24. In the Solution Pad, in the Notes project, expand App.xaml, and double-click App.xaml.cs to open it:

    

25. In App.xaml.cs, remove all of the template code and replace it with the following code:

    using Xamarin.Forms;
    
    namespace Notes
    {
        public partial class App : Application
        {
    
            public App()
            {
                InitializeComponent();
                MainPage = new AppShell();
            }
    
            protected override void OnStart()
            {
            }
    
            protected override void OnSleep()
            {
            }
    
            protected override void OnResume()
            {
            }
        }
    }
    

    This code defines the code-behind for the App class, that is responsible for instantiating the application. It initializes the MainPage property to the subclassed Shell object.
