Image Resizetizer for WinUI and Uno Applications

Whilst I was working on migrating the WeatherTwentyOne app from Maui to Uno I noticed that the Maui application includes a number images as SVG files. However, in the XAML there are only ever references to PNG files. On closer inspection of the bin folder for the WinUI project I noticed that for each SVG … Read more

Converting the WeatherTwentyOne app from dotnet Maui to Uno

As the dotnet Maui team continue to churn out each preview, it’s great to see some of the showcase apps coming together. One of these is the WeatherTwentyOne app that David Ortinau has been working on. Whilst I’ve been doing a lot of work with the Uno platform recently, I haven’t been spending as time … Read more

Ditch that Packaging Project with the Windows App SDK (Windows UI)

One of the most annoying “features” of both UWP and WinUI/ProjectReunion WindowsAppSDK apps is the need to generate a package. With UWP development, the packaging was built into the UWP project. However, with the WindowsAppSDK, a separate packaging project is currently required. In this post we’re going to walk through how you can remove this … Read more

Nuget Package Explorer (nuget.info) is a PWA powered by Uno Platform

As a true demonstration of the capabilities of the Uno Platform the Nuget Package Explorer (source on GitHub / Microsoft Store) is now available at https://nuget.info. For more information read the announcement. One thing that’s not immediately obvious is that https://nuget.info is in fact a PWA. In Edge (and Chrome) you should see an icon … Read more

Getting Started with Project Reunion (Windows UI) and Visual Studio 2022

There’s a bit of fanfare going on at the moment because Microsoft have released the first preview of Visual Studio 2022 (announcement / download) which is significant because this is the first version of Visual Studio which will be 64bit.

Startup Performance, Skia and the Future of Cross Platform Apps Built with .NET

Over the last week I’ve been exploring different ways to measure the time it takes for an app to launch and be ready for the user to interact with. I’ll go into more detail on this topic in subsequent posts but I wanted first to take a bit of a side track into thinking about … Read more

Running a Windows UI (Project Reunion) App as Partial Trust (Windows App Container)

I’ve covered this a couple of times already but it’s already possible to run a Windows UI (aka WinUI / Project Reunion) app as “partial trust”. This is roughly equivalent to the security context of a UWP application. However, there are some difference, which I’m assuming Microsoft will have to bridge if they’re going to … Read more

Visual Designer, Hot Reload and Beyond

In the last couple of years we’ve seen a massive spike in interest around “Hot Reload” thanks to the popularity of frameworks such as React/React Native and more recently, Flutter. The goal of Hot Reload is to allow developers to iteratively change their application code, whilst debugging their application – this cuts down considerably the … Read more

Running Your Windows UI / Project Reunion App in the Windows App Container (sandbox)

In a number of my previous posts I’ve challenged the need for Windows UI (WinUI3) to continue to support UWP. In nearly every instance I get push back from the community regarding all the features that are missing from Project Reunion and that UWP needs to be the future – but why I ask? wah, … Read more

How to run a WinUI 3 (Project Reunion) app on Windows 10X (Xbox and Hololens)

If you look at what Microsoft is working on with Project Reunion, it’s clear to see that they’ve set a vision to reunite the various groups of Windows developers. The aim is not to have every developer using exactly the same technology stack but rather to give every developer access to the richness of the … Read more

Adding Some Behaviors to Your WinUI Uno Application

With the recent release of Windows UI and support for cross platform offered by the Uno Platform, it’s going to take a little while for the various UWP libraries that we’re familiar with to be ported across. They firstly need to be ported to Windows UI and then they need a Uno build. The Uno … Read more

Restyling Controls in an Uno (Windows UI) Application

In my previous post, Multi-Platform PixelPerfect UI with Windows UI and the Uno Platform, I demonstrated how applications built using Project Reunion (i.e. Windows UI), coupled with the Uno Platform, could deliver an identical user experience across a variety of platforms. In this post I’m going to walk through changing the style of one of … Read more

Multi-Platform PixelPerfect UI with Windows UI and the Uno Platform

As we progress through the various previews of .NET 6 it’s great to see the transition happening from Xamarin.Forms to dotnet MAUI. The other day, James Montemagno tweeted out an image that showcases the same application running on iOS, Android, MacOS and Windows (which is now based on WinUI Desktop!). This tweet inspired me to … Read more

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

Two years ago I posted on Getting Started with Platform Uno which focused on starting with a UWP application and extending it cross platform using the Uno Platform. For those tracking developments in the Windows development space, you’ll be aware that the 0.5 version of Project Reunion has just been released. It seem fitting to … Read more

Naming, Versioning and Releasing Project Reunion and Windows UI

As the first release of Windows UI 3.0 is imminent, there’s a bit of a dialogue going on about its relationship with the parent project, Project Reunion.
