The Model-View-ViewModel (MVVM) is a software design pattern that is structured to separate program (business) logic and user interface controls. The main advantage is, that the program logic is fully unit-testable as it functions independently of the UI controls (loosely coupled). It is very popular among the developers of XAML-based UI frameworks such as WPF, UWP, Xamarin.Forms, .NET MAUI, WinUI, and even other 3rd Party frameworks such as Uno.

This is a follow-up article describing the new features added to the latest release that supports .NET MAUI RC1. For installation and options available in this template, a detailed article is linked here.
This release is now loaded with 4 new features:
First things first, .NET 6 RC1 and .NET MAUI Preview 8 got released this week but the big breaking news is that .NET MAUI will be ready for Production use (General Availability) only by early Q2 of 2022 (next year) and NOT as originally planned with .NET 6 GA by Nov 2021.
This is definitely sad news for all those Xamarin/.NET MAUI developers who wanted to leverage this brand-new architecture. Hopefully by that time, if additional targets such as Linux/Wasm gets onboard, it would be worth waiting.
Resource management is one of the key aspects of app development, be it mobile or desktop. The developer has to deal with a variety of resources ranging from images, fonts, splash screen, styles, and raw assets like HTML, PDF, or could be even simple text files.
That too when it comes to cross-platform development, each platform has its own way of managing resources and it’s a daunting task for the development team to know and manage all those things. For example, image requirements in multiple sizes to support devices with various resolutions for a rich experience. Fortunately, icon fonts solve a part of this problem by auto-scaling. But still, font is managed differently in each of the platforms.

Windows 11 Update
If you work on Xamarin.Android, Xamarin.Forms or .NET MAUI, then think before you upgrade to Windows 11 on that machine. The reason being Android Emulator fails to start and seems many of them have already reported this issue via Windows Feedback and on other channels. I’m yet to find a solution to this issue. I updated to Windows 11 21H2 OS build 22000.100. And it’s currently running OS build 22000.194 (same as RTM version). The only possibility, for now, is to make use of a physical device. Thanks to Wi-Fi debugging.
With .NET 6 Preview 6 released on Jul 14, 2021, and now Preview 7 released on Aug 10, 2021, .NET MAUI progressed a lot with Workloads, Gestures, Clipping, Alerts, New Layouts, and mainly first-class support for Visual Studio 2022 (with Preview 3.x). But, there is a catch in here. NO item templates for Visual Studio for now :-(.
Update: This extension is now updated to support .NET MAUI Preview 10 with VS2022 Preview (17.1.0 Preview 1.0) IDE and .NET MAUI (Preview) Mobile Development workload installed. This can be downloaded and installed from the same link mentioned in this article.
Update: A more advanced all-in-one .NET MAUI App project template is now available to install. Check out this article for more details.
This article is kind of an update to the previous one to describe the use of Comet for .NET Mobile by James Clancey to debug the .NET MAUI project and it’s available as an extension to VS Code.
This cute little extension automates the build and debug into a simple action rather than manually configuring it as described in the previous post.
To get started, launch VS Code, open Extensions (Shortcut: Ctrl+Shift+X), look for the Comet for .NET Mobile and get it installed.
Update: Completed sample of this article is now available in GitHub, can be accessed from .NET MAUI Samples
In the previous post, described how we can set up a Dev environment for playing with .NET MAUI and steps to create a new project from the template provided and then went on to build and run using .NET CLI.
And in this post, am going to detail how we can achieve build, run, attach the debugger and add breakpoints within Visual Studio Code. Will continue with the same TestApp project that we created earlier.
You might wonder whether you’ve read the title of this post correctly, yes, of course, .NET MAUI project template is now available from the .NET CLI toolset and VS IDE.
Both VS2019 and VS2022 for Windows are now provisioned with project templates for both Maui as well as Maui Blazor app models. Use VS2019 16.11 Preview 4.0 or VS2022 Preview 3.0 or later version to build the project.
And, users on macOS can continue to use VS Code for time being as Microsoft is doing a complete revamp of Visual Studio for Mac. Develop MAUI app in VS Code with Comet for .NET Mobile extension. For further details, read this article.
Update: A far more advanced all-in-one .NET MAUI App project template is now available to install. Check out this article for more details.
Have published a VS extension to install the item templates that target .NET MAUI Preview. To know more about it, take a look at this .NET MAUI – Templates for Visual Studio article.
