Getting Started with the Uno Platform (Project Reunion/WinUI)

Stop Talking about UWP

Ok, I know this post is probably going to annoy all those UWP loyalist out there that can’t unpackage their love for the platform and realise that Windows development is in the process of moving on. One of probably the biggest marketing nightmares that Microsoft has unleashed is UWP. To different people, UWP means different … Continue reading “Stop Talking about UWP”

Converting Xamarin.Forms to WindowsUI and Uno: StackLayout v StackPanel

When moving from Xamarin.Forms across to WinUI, one of the simpler changes to make is to switch out StackLayout for StackPanel.

In this post we’ll look at why the StackPanel replacement doesn’t always work, and what … Continue reading “Converting Xamarin.Forms to WindowsUI and Uno: StackLayout v StackPanel”

Converting Xamarin.Forms to WindowsUI and Uno: SafeArea to VisibleBoundsPadding

Converting a Xamarin.Forms application across to use WinUI + Uno is mostly straight forward as a lot of the XAML is either the same, or has an equivalent. When you’re dealing with platform specifics, one thing you might come across is the SetUseSafeArea call. For example: The Uno platform exposes the concept of safe area … Continue reading “Converting Xamarin.Forms to WindowsUI and Uno: SafeArea to VisibleBoundsPadding”

Simple WinUI + Uno Calculator

A week or so ago David from the XF/Maui team kicked of a thread on twitter challenging devs to add a simple addition to a simple calculator.

I’m going to try to keep as close to … Continue reading “Simple WinUI + Uno Calculator”

Async Support for Executing Storyboards in UWP and WinUI

Sometimes I forget just how old and dated XAML is, and how little advances Microsoft has made to make it easy to work with.

Breaking a Developer Ecosystem by Changing a Namespace

The next 6-12 months are going to be super exciting with both preview and releases planned for WinUI, Project Reunion and Maui (aka Xamarin.Forms).

Using ImageSharp in your WinUI – Uno Cross Platform App

This post originated from a tweet demonstrating how easily you can use the ImageSharp library in a Blazor server side app to generate images.
