How to Disable Individual GridView and ListView Items in a XAML Application (WinUI + Uno Platform)

One of the most significant aspects of the XAML based applications is the concept of lookless controls.

The Windows App SDK and the Uno Platform provide out of the box styles for … Read more

Dotnet (.NET) Performance Tracing for WinUI, Uno and Maui Applications

With the transition from UWP to WinUI and from Xamarin iOS/Android to .NET for iOS and Android, we’re seeing the convergence of application development in the .NET ecosystem. This convergence shouldn’t be undervalued and is particularly evident when you realised that all of these once disparate platforms, can now take advantage of the common tooling … Read more

Simplify NuGet Package Versions in your application with Central Package Management

A common problem for multi-project applications, frameworks or libraries is how to manage the versions of NuGet package that are referenced.

In this post … Read more

Visual Studio: How to Pair to Mac for iOS Development on Windows

I have to start this post by pointing out what a major bonus it is for .NET developers that you can build, deploy and debug an iOS application on Windows – that’s right, if you didn’t already know this, if you’re using Xamarin (now net6 ios/android), Xamarin.Forms (now dotnetmaui) or Uno Platform, you can do … Read more

Xamarin.Forms, .NET Maui and the Uno Platform

The .NET Maui team at Microsoft recently dropped Release Candidate 1, so I thought it worth taking a quick look at how it compares to both it’s predecessor, Xamarin.Forms, and the Uno Platform, which is arguably the market leader for building multi-platform application with .NET. If you missed the announcement by Microsoft, here’s a tweet … Read more

UI Testing for WASM (WebAssembly) with the Uno Platform

One of the guilty truths of software development is that despite our best efforts we never write enough tests, and seldom do we write enough automated tests. This isn’t entirely our fault because for some reason testing frameworks, particularly those for UI testing, always seem to be an after thought. In this post we’re going … Read more

Tutorial: Hello World with Microsoft Orleans
