• Once the project is created, we can able to see the Android, iOS, Windows and other running options in the toolbar. Press the emulator or run button to build and run the app
  

Implementation:

• To take a screenshot, .NET MAUI provides us with the IScreenshot interface which is exposed by the Screenshot.Default component in the Microsoft.Maui.Media namespace.
• In Solution Explorer, click MainPage.xaml and replace the page content with what is shown below:
• Open the MainPage.xaml.cs file and the page content as shown below:
• IsCaptureSupported: Returns a bool value – Gets a value indicating whether the capturing screenshots are supported.
• CaptureAsync: Returns an ISscreenshotResult. – It is responsible for taking screenshots of the current application. Therefore, we can get various information about it, such as width and height.
• Stream: IScreenshotResult also has a Stream property that is used to convert the screenshot to an image object.
• Assign the derived stream value to the image control as ImageSource.

In this tutorial series, we will see how to create a CardView in .Net MAUI using Border control. In .NET Maui provided Microsoft.Maui.Graphics library which provide us a consistent UI drawing API based on native graphics engines, thus making it easier for us to add borders, corners customisations, and shadows for most of the controls and layout contained in .NET MAUI. The new Border Control allows us to add Borders to a single element as a content (can be both a control and a Layout). This brings us a very flexible behavior to control of each corners: top-left, top-right, bottom-left, bottom-right, with our user interface, some of those cases can be adding the border to a button and rounding the upper left and lower right corners.

Implementation:

• Open the MainPage.xaml file and add the following border control. Border Properties

  Stroke	Sets the color that the border will take on.
  StrokeThickness	It’s the thickness (width) of the Border.
  StrokeDashOffset	It’s the distance within the dash pattern.
  StrokeDashArray	Collection of values, which is responsible for specifying the Dash pattern and the spaces used for the border to implement.
  StrokeLineCap	Defines the start and end stroke that the border will have. For the stroke shape, it receives the following values: Flat, Round, and Square.
  StrokeMiterLimit	Limit on the ration of the miter length to half of the stroke thickness.

• We also having the StrokeShape property, which allows to modify the shape of the Stroke based on a Shape (the one you want), in addition to this Shape you can modify the edges as you need.
• We also add shadow property to apply in CardView.
• The final output will be like below when we come all the above properties come together.

Introduction

Xamarin.Essentials

Xamarin.Essentials provides developers with cross-platform APIs for their mobile applications. Android, iOS, and UWP offer unique operating system and platform APIs that developers have access to all in C# leveraging Xamarin. Xamarin.Essentials provides a single cross-platform API that works with any Xamarin.Forms, Android, iOS, or UWP application that can be accessed from shared code no matter how the user interface is created.

Text-to-Speech

This enables an application to utilize the built-in text-to-speech engines to speak back text from the device and also to query available languages that the engine can support.

Coding Part

Steps

1. 1: Creating new Xamarin.Forms Projects
2. 2: Implementation of Text to Speech in Xamarin Forms

Step 1: Creating new Xamarin.Forms Projects

Create New Project by selecting "New Project" à "Xamarin Cross Platform App" and Clicking "OK". Note: Xamarin.Forms version should be greater than 5.0.

Then Select Android and iOS Platforms as shown below with Code Sharing Strategy as PCL or .Net Standard and Click OK.

Step 2: Implementation of Text to Speech in Xamarin Forms

In this step, we will see how to implement the functionality in Xamarin.Forms.

Platform Specific Changes:

• If your project's Target Android version is set to Android 11 (R API 30) you must update your Android Manifest with queries that are used with the new package visibility requirements.
• Open the AndroidManifest.xml file under the Properties folder and add the following inside of the manifest node:

Xamarin Forms App Changes:

• Add a reference to Xamarin.Essentials in your class:
• Text-to-Speech works by calling the SpeakAsync method with text and optional parameters, and returns after the utterance has finished.
• This API provide more options on how the audio is spoken back with SpeechOptions that allows setting the volume, pitch, and locale.
