How do you open the browser, dialer, or email from MAUI?

Beginner

Answer

Use the launcher/communication APIs: Browser.Default.OpenAsync for URLs, PhoneDialer.Default.Open for phone numbers, Email.Default.ComposeAsync for email, and Sms/Map for others. These invoke the platform's default apps rather than embedding them.
await Browser.Default.OpenAsync("https://w3teacher.com",
    BrowserLaunchMode.SystemPreferred);
PhoneDialer.Default.Open("+15551234567");
Real-world example A contact screen opens the dialer with the support number and launches the website in the system browser.
