I am Writing a Book - Learn WinUI 3.0

Hello UWP developers!

I wanted to provide an update on this UWP Tips blog. Most of my focus this year is going to be on my new WinUI side project. I am writing a book for Packt Publishing titled Learn WinUI 3.0. The book is due out this fall. That will hopefully coincide with a final or near-final release of WinUI 3.0.

As I am working on the book, I plan to blog about my experience with WinUI 3.0 through its preview and beta stages this year. If you would like to follow along, I encourage you to follow my WinUI Tips blog. I will occasionally cross-post or create summary blog posts here to catch up with my UWP Tips followers. Your best bet to stay informed is to subscribe to both blogs (and WPF Tips, while you're at it).

If you have any suggestions for the book or things you would like to learn more about, don't hesitate to drop me a line on Twitter or LinkedIn.

Thanks for reading!

Mastering Xamarin.Forms Book Review on Morning Dew

Heads-up UWP app developers! I'm sure you're aware that you can build cross-platform apps with Xamarin.Forms, targeting UWP in addition to iOS and Android. I think that anyone familiar with building UWP apps for Windows will get a lot of great information from Ed Snider's new 3rd Edtion of Mastering Xamarin.Forms from Packt Publishing

Go check out my full review of the book on my Morning Dew blog.

Happy Coding!

.NET Core Book Review on Morning Dew

Hello UWP developers!

I just published a book review on my Morning Dew blog that may be of interest to my readers here. C# 8.0 and .NET Core 3.0 - Modern Cross-Platform Development is a new title by Mark Price from Packt Publishing. While it covers a broad range of .NET Core topics, there are chapters on both Xamarin and Windows Desktop application development.

Quick Tip - Hot Fix Update for Windows Template Studio Now Available

Hello, fellow Windows devs. I will be back with some fresh UWP developer tips soon! In the meantime, here is a quick tip if you use Windows Template Studio and have the Visual Studio 2019 Preview installed on your machine.

Last week, Windows Template Studio version 3.4.19254.01 was released to address two issues specific to the VS2019 Preview.

  • Issue #3295 - Relates to adding an MVVM Light app to a Windows Template Studio project.
  • Issue #3309 - An error occurs when generating a project with the default selections.

There are no workarounds listed for either issue. Although both are specific to VS2019 Preview and seem to be limited in the scope of their problems, I like to patch my dev software as fixes become available. You can install this update whether you're running WTS with VS2017 or VS2019 Release/Preview.

You can either get the VSIX for the release here or if you have Windows Template Studio installed, open the Visual Studio Extensions dialog and check for updates. The source code for the release is also available for download if you want to have a peek under the hood.

Happy coding!

UWP Tip #26 - Playing on the Uno Platform Playground

Have you heard of the Uno Platform project? Uno enables UWP developers to truly create universal C# applications with UWP XAML. Reuse your views, view models and supporting code across Windows 10, iOS, Android and the web (via WebAssembly).

Get started by visiting the Uno web site, read some how-to articles on their blog, and check out the source code on GitHub. Then download Visual Studio extension installer (.VSIX) from their latest GitHub release, and do a File-->New Project in Visual Studio.

But this is a post for next time. Today, we're going to take a look at how you can try Uno on any computer, regardless of what tools or extensions are installed. Let's try the Uno Platform Playground.

In any modern web browser, simply go to Here is the screen that will greet you.

You get a neat little editor in the browser complete with XAML Editor, another editor to create JSON sample data for your page's data context, and a live preview pane that creates the page via WebAssembly. The left side has what appears to be a toolbox, but is actually a series of links for viewing the sample/starter code for each control, along with a handful of more extensive samples. At the top, you can click run to render your page or keep AutoRun checked to get a live preview as you modify the XAML and data. The Save Snippet link in the upper-right corner will copy the XAML snippet to your clipboard.

Add a little XAML of your own and maybe a line of data in the JSON, and watch the live preview render the output with your updates.

I added a horizontal StackPanel containing a HyperlinkButton and two Button elements.

<StackPanel Orientation="Horizontal" Spacing="10">
    <HyperlinkButton Content="Windows Dev Center"
    <Button Content="Click Me"/>
    <Button Content="Click Me Too"/>

Let's have a look at the "Cards" sample.

This sample uses a ListView with a DataTemplate to create the look and feel of cards. The ListView's ItemsSource is set to the JSON in the Data Context editor. You can edit any of this and watch the preview pane reload with your changes. Remember to click Run if you have disabled AutoRun.

The Playground is a great place to play with the tools and copy some of your "play code" into a real live project in Visual Studio. Curious about how the Playground was built? That source code is also available. View it here.

Go play today, and leverage your UWP skills across every platform! Happy coding and #uwpeverywhere! Tags: ,,
