Integrating .NET MAUI with Aspire: A Comprehensive Guide

Aspire is now the talk of the town. You can build and orchestrate all the dependencies from one single place. In fact, it’s stack streamlined. Learn more about Aspire here.

This article discusses how to integrate .NET MAUI, Microsoft’s cross-platform UI framework, with Aspire.

Aspire supports .NET by default, but since .NET MAUI is designed for multi-targeting from a single project, it presents a minor issue. I’ll offer a workaround until it’s officially supported (coming soon).

For this, I’m using .NET 10 File-based Apps for simplicity. Aspire v9.5 supports this new feature. Consult this article to know more about C# File-apps.

How to Update .NET MAUI 9 for Apple Xcode 26

Following its annual release cadence, Apple formally announced its updated hardware and software during the Apple Event in early September.

The OS version numbers are now all v26 to avoid confusion. This includes the updated developer tool, Apple Xcode, which is also at v26.

Regardless of the development framework, apps submitted to the App Store must always target the most recent iOS SDK. Hence, support for the latest version of Xcode is crucial.

.NET MAUI has announced its support for Apple Xcode 26 in the Stable channel of the .NET 9 SDK. More details here.

Using C# Ignored Directives: A Guide for Programmers

C# – Preprocessor Directives are highly useful for writing code that can be compiled conditionally, depending on factors like the target framework, target platform, or build configuration.

For example:

#if NET9_0_OR_GREATER
// The code within this block will execute only on .NET 9 or higher
#endif

#if ANDROID
// The code within this block will execute only on the Android OS
#endif

#if DEBUG
// The code within this block will execute only in Debug mode
#endif

C# – Ignored Directives have a similar syntax but are ignored by the compiler because they are for tooling.

The real purpose of this feature is to execute a C# source file directly from the CLI. It doesn’t need a project file. Now, even the plain console app requires a project file, despite the much-simplified top-level statements feature.

.NET MAUI – Enable Debugger-Detached XAML Live Preview in Visual Studio 2022

Not confined to .NET MAUI, the XAML Live Preview functions as an invaluable tool for inspecting the UI and its associated properties in XAML apps overall.

However, it is imperative that the app be connected to the debugger, is it not? Yes, that is prior to the intro of the debugger-detached XAML Live Preview in VS2022, v17.13 Preview 1.0.

Yesterday, during the .NET MAUI session at .NET Conf 2024 (YouTube clip linked), David and Rachel provided an insightful overview of its functionality.

To know about this virtual event, consult this .NET Conf 2024 article and this detailed article outlining the comprehensive features of .NET MAUI 9.

Due to the underlying external dependencies, the support policy of .NET MAUI differs significantly from .NET, each major release will be supported only for 18 months. So, if you’re using .NET MAUI 8, support will cease by mid-May 2025 (in another 6 months). Hence, it’s necessary to plan for your app migration to .NET MAUI 9. An article has already been published detailing the comprehensive features of .NET MAUI 9.
