Current sessions

Introduction to App Development with .NET MAUI

.NET MAUI provides an extremely flexible and powerful way to create apps for Android, iOS, macOS, and Windows, from very simple to extremely robust and complex. Is this one size fits all? Where should you start? In this session I'll run through what .NET MAUI is, how it fits in the .NET ecosystem, differences with Xamarin and how to get started yourself!

.NET MAUI Blazor - Build Hybrid Mobile, Desktop, and Web apps

Blazor enables building client-side web UI with .NET, but sometimes you need more than what the web platform offers. Sometimes you need full access to the native capabilities of the device.

You can now host Blazor components in .NET MAUI apps to build cross-platform native apps using web UI. The components run natively in the .NET process and render web UI to an embedded web view control using a local interop channel.

This hybrid approach gives you the best of native and the web. Your components can access native functionality through the .NET platform, and they render standard web UI. .NET MAUI Blazor apps can run anywhere .NET MAUI can (Windows, Mac, iOS, and Android).
