With Xamarin you can use C# to create Android and iOS apps. Plus, that C# codebase will be 100% shared between projects, and compile to native code, so performance is not impacted.
| Share C# Code | Create the UI with XAML |

| Code your whole logic once, share it between the Android and iOS native projects. | Xamarin translates your XAML code into native UI elements, so your apps feel native -because they are. |
| SQLite | REST | MVVM |
|---|---|---|

| Learn to define the user interface using XAML, handle user interactions using C#, use a local database to store and retrieve data, and list all the information. | Get the device's location and use it to get a list of nearby venues using the Foursquare REST API and HTTP requests. Then update the SQLite table with that info. | Clean your code by implementing the MVVM architectural pattern and feel like an expert using Binding, Commands and Observable Collections. |
Curious about what you will learn? Here is the list of topics that we cover day by day:
- XAML and Events. Defining the interface and handling user interactions.
- Using XAML Styles. Reusing XAML code with Style Resources.
- Creating an SQLite Database. Prepare the projects to use SQLite and get the file's path.
- Inserting to the Database. Model the database table, create a connection and start adding elements to the table.
- Reading and Listing a Table. Read the database table and list the retrieved elements in a ListView.
- Getting the User's Location. Get the user's permission to access location, then get the coordinates.
- Making REST Requests. Make HTTP requests to Foursquare's REST API to get nearby venues.
- The INotifyPropertyChanged interface. Implement the interface to notify the view of property changes.
- Defining and Binding Commands. Substitute event handlers with Commands.
- Using Observable Collections. Notify the view of collection changes with the ObservableCollection class.
