Tutorial – Building a Kanban Style Todo App (code included)

… What better way to start learning a new technology than with a tutorial that includes all the sample code? When you finish, or fork, the tutorial you will end up with an application like this: Steven Giesel recently published a 5-part series documenting his experience building a Kanban-style Todo-app using Uno Platform for the first time. Follow along as he takes you through Uno Platform set-up, his thoughts on the platform, and finally a hands-on demonstration of creating a Todo app Kanban-style that runs in your browser, desktop, or mobile! For those of you who are new to Uno Platform, or looking to start using the platform, it allows for building Mobile, Desktop, and WebAssembly apps with C# and XAML and there has never been a better time to get started. We’ve spent a significant portion of our recent releases (Uno Platform 4.0 and 4.1)  improving performance and features, and the tools now available to you to create amazing apps are paving new opportunities Part One – Introduction and Environment set up As a first-time user, Steven gets down to the basics of Uno Platform and covers the differences between the platform and .NET MAUI. With a basic understanding of the

Uno Platform 4.1 Update for .NET 6 Mobile Preview 14

The .NET team has been steadily releasing a set of updates to the .NET 6 Mobile previews. Last week’s update was Preview 14, which came at just about the same time as Uno Platform 4.1 release. Following .NET 6 mobile Preview 14, we’re publishing the Uno Platform 4.1.9 service update.  This update includes a new set of binary breaking changes added in .NET 6 Mobile Preview 14, which requires the use of Visual Studio 17.2 Preview 2. If you update to Visual Studio 17.2 Preview 2, you will need to be on Uno Platform 4.1.9 or later.  To use this new preview in Uno Platform projects, you’ll need a few steps:  Update to the latest uno-check preview dotnet tool update -g uno.check –version 1.2.0-dev.10 and then run uno-check –pre Update your NuGet packages to Uno.UI.* 4.1.9 or create a new project from the templates If you’re building on a mac, either directly or through VS for Windows, you’ll need to run uno-check on the mac as well. Make sure that your Visual Studio 2022 Uno Platform extensions are updated to 4.1.9 (it should be automatically updated) Note that if you intend to build for iOS, Xcode 13.3 is required and that this version

Uno Platform 4.1 – 30% Perf Boost, Android 12, .NET 6 Mobile Preview 13 and more

It has been just over 3 months since our 4.0 release, and we’ve used that time to focus on performance as well as bringing the latest .NET 6 innovation to Uno Platform. By simply updating your application to the newest bits you will notice a significant boost to your app performance. This release packs over 200 new feature requests, bugs, and issues you raised. We welcomed a few great contributions from our community, which is now over 210 contributors strong! Thanks for all you bring to Uno Platform. Let’s unpack the 4.1 release. Performance updates For this release, we’ve made numerous changes to a wide range of parts from the Uno Platform, such as Style resolution, layout and measure pass performance, memory consumption and allocations which result in up to 30% performance improvements in some scenarios. Measure Dirty Path The measure pass (MeasureOverride and InvalidateMeasure) is an important contributor to the computations performed to layout the UI, and any optimization performed in this area can significantly improve the time to show the first UI or improve binding update. We’ve changed the way MeasureOverride is invoked when InvalidateMeasure is called, where previously all ancestors of a control would be re-executing MeasureOverride,

Uno Platform Weekly Live Coding

Among our many features and initiatives, one that we want to highlight to our community is our weekly live-coding session that happens every Tuesday. Uno Platform Live Coding sessions are hosted by Uno Platform CTO Jérôme Laban and for roughly 60 minutes, Jérôme whiteboards and codes live side projects with Uno Platform, demonstrates new features, and troubleshoots different issues and bugs that arise. The Live coding sessions allow Uno Platform users to witness the thought process of a senior software engineer solving a problem and how it is then implemented into code. Users can join live and ask questions at any time and clarify concepts they may be unsure of. If you have any topic requests, questions that you want to be answered, feel free to reach out to @jlaban. Make sure you sign up for notification when Jérôme goes live on his Twitch channel – (re)starting next week March 8th, when he is back from vacation. Even heroes deserve to take a break! About Uno Platform For those new to Uno Platform – it allows for creation of pixel-perfect, single-source C# and XAML apps which run natively on Windows, iOS, Android, macOS, Linux and Web via WebAssembly.

XAML Fundamentals for Web & Mobile: ListView

It’s 2022 and XAML on the Web is now as relevant on Mobile and Web as it traditionally was on Windows Desktops. Between 2005 and 2013, Beatriz Stollnitz authored a series of blogs that covered a variety of XAML fundamentals and became a treasure trove of resources for developers. As you can imagine much of the information has since become outdated and most of the code samples no longer work out of the box with the latest version of Visual Studio. Last year, Nick Randolph, an Uno Platform contributor, revived the almost 10-year-old WPF blog series on his .NET Travels, and we’re picking up where he left off. In this continued version of XAML Basics, we added a focus on Web and Mobile where XAML is now very applicable. We carry on the efforts of making the adjustments needed to bring each control up to date as well as provide equivalent examples that work to include XAML cross platform support via Uno Platform and WinUI to Web, iOS, macOS, Android and even Linux! ListView A sizable benefit which came during the early days of WinRT XAML was the refreshed ListView and GridView controls. Microsoft engineered these controls to be smooth

A Deep Dive Into Uno Extensions

Our Uno Platform 4.0 release brought with it a lot of updates and fixes to the platform but most importantly it also allowed us to unveil a series of productivity tooling and extensions that drastically help bring your app to market faster. One of those tools introduced was Uno Extensions, simply put, it allows you get started without having to write code from scratch, getting you to a fully functional project in minutes and saving you months of development time. Microsoft has extracted a host of capabilities outside of ASP.NET and made them available through Microsoft Extensions – covering hosting, logging, configuration, etc. In turn, Uno Platform Extensions are based on those Microsoft Extensions. To get a better understanding of Uno Extensions and how you can utilize them in your workflow, MVP and Uno Contributor Nick Randolph gave us a glimpse of Uno Extensions in action during his UnoConf 2021 session. Listen as he walks you through creating a host and registering services to more complex extensions like using the navigation extensions to navigate between pages views and the application. This session previews only a few of the available extensions but there are additional Uno extensions that we haven’t covered

This article will be more UI focused. It will discuss ways you can visualize the invoice and client data using adaptive styling on UI elements and layouts. I’ll be addressing two key areas in UX development: 1. Styling 2. Layouts & Controls 1. STYLING This is a blueprint that defines design standards for a collection of UI elements and interactions. In the demo Uno Platform application, I made use of ThemeResource and Merged Dictionaries to create styles for individual UI elements, dark and light themes. In the Microsoft XAML space, ThemeResource
