Command Line Parser on .NET5

Alexandre Zollinger Chohfi (@AlexandreChohfi) writes:

If you are used to command-line apps, passing arguments to other apps is a very common task. Yes, you can manually parse those values, but once you have multiple parameters it can be a very error-prone code (which is mostly boilerplate anyway). This seems like a problem that someone else might have fixed already, right? So of course we can find a NuGet library that helps us parse these arguments.

Getting Ready for .NET 6 and .NET MAUI

David Ortinau (@davidortinau) writes:

With .NET 6 previews starting right around the corner, it is time to start getting excited for the new .NET Multi-platform App UI (MAUI) that was announced at BUILD 2020. This year of .NET has a lot of amazing things for client application developers.

…

.NET MAUI is the evolution of Xamarin.Forms, a cross-platform mobile first framework for Android, iOS, and UWP. Building upon 7 years of experience supporting customers from independent developers to some of the world’s largest companies, we are improving the core of the product, speeding up UI rendering, investing in consistent design systems, and extending from mobile to desktop.

WinUI 3.0 Misconceptions – Nick’s .NET Travels

WinUI 3 is a new, cross-platform UI initiative from MS that has as a goal to separate the UWP UI/Application framework away from Windows.

Recently Nick came across a twitter thread talking about WinUI 3.0 (WinUI3) and how it failed to live up to expectations. Hopefully @JaykeBirdCoding won’t mind him going through his tweets and providing his thoughts. @JaykeBirdCoding!

Summary: You need to look into both Uno and outside the .NET ecosystem if you’re serious about cross platform.
