Platform features
Each platform that .NET Multi-platform App UI (.NET MAUI) supports offers unique operating system and platform APIs that you can access from C#. .NET MAUI provides cross-platform APIs to access much of this platform functionality, which includes access to sensors, accessing information about the device an app is running on, checking network connectivity, storing data securely, and initiating browser-based authentication flows.
.NET MAUI separates these cross-platform APIs into different areas of functionality.
Application model
.NET MAUI provides the following functionality in the Microsoft.Maui.ApplicationModel namespace:

| Device display | The DeviceDisplay class enables an app to read information about the device's screen metrics. For more information, see Device display. |
| Device information | The DeviceInfo class enables an app to read information about the device the app is running on. For more information, see Device information. |
| Device sensors | Types in the Microsoft.Maui.Devices.Sensors namespace provide access to the device's accelerometer, barometer, compass, gyroscope, magnetometer, and orientation sensor. For more information, see Device sensors. |
| Flashlight | The FlashLight class can toggle the device's camera flash on and off, to emulate a flashlight. For more information, see Flashlight. |
| Geocoding | The Geocoding class, in the Microsoft.Maui.Devices.Sensors namespace, provides APIs to geocode a place mark to a positional coordinate, and reverse geocode a coordinate to a place mark. For more information, see Geocoding. |
| Geolocation | The Geolocation class, in the Microsoft.Maui.Devices.Sensors namespace, provides APIs to retrieve the device's current geolocation coordinates. For more information, see Geolocation. |
| Haptic feedback | The HapticFeedback class control's haptic feedback on a device, which is generally manifested as a gentle vibration sensation to give a response to the user. For more information, see Haptic feedback. |
| Vibration | The Vibration class enables you to start and stop the vibrate functionality for a desired amount of time. For more information, see Vibration. |
Media
.NET MAUI provides the following functionality in the Microsoft.Maui.Media namespace:
| Functionality | Description |
|---|---|
| Media picker | The MediaPicker class enables you to prompt the user to pick or take a photo or video on the device. For more information, see Media picker. |
| Screenshot | The Screenshot class enables you to capture the current displayed screen of the app. For more information, see Screenshot. |
| Text-to-speech | The TextToSpeech class enables an app to utilize the built-in text-to-speech engines to speak text from the device. For more information, see Text-to-Speech. |
| Unit converters | The UnitConverters class provides unit converters to help you convert from one unit of measurement to another. For more information, see Unit converters. |
Sharing
.NET MAUI provides the following functionality in the Microsoft.Maui.ApplicationModel.DataTransfer namespace:
| Functionality | Description |
|---|---|
| Clipboard | The Clipboard class enables an app copy and paste text to and from the system clipboard. For more information, see Clipboard. |
| Share files and text | The Share class provides an API to send data, such as text or web links, to the device's share function. For more information, see Share. |
Storage

| Preferences | The Preferences class helps to store app preferences in a key/value store. For more information, see Preferences. |
| Secure storage | The SecureStorage class helps to securely store simple key/value pairs. For more information, see Secure storage. |
Access platform APIs
.NET MAUI platform-specifics allow you to consume specific functionality that's only available on a specific platform. For more information, see Android platform-specifics, iOS platform-specifics, and Windows platform-specifics.
In situations where .NET MAUI doesn't provide any APIs for accessing specific platform APIs, you can write your own code to access the required platform APIs. For more information, see Invoke platform code.
