Microsoft has released .NET Aspire 9.3, introducing several enhancements aimed at improving the developer experience. The update includes quality improvements, integration enhancements, and API updates, reflecting Microsoft's commitment to refining its cloud-native development tools.

Here are some of the updates:

AI Debugging Assistant: Review hundreds of log messages with a single click, trace root causes across multiple apps, spot performance issues, and decode obscure error codes using GitHub Copilot's AI smarts—all without leaving your dashboard.
Context Menu in Resource Graph View: A new context menu gives you quick access to a resource’s telemetry, commands, and URLs directly from the graph view.
Enhanced Tracing: Visualize outgoing calls to resources that don’t emit telemetry—like databases, caches, and infrastructure components—ensuring nothing is missed.
Integration Updates: New capabilities include self-hosting a YARP instance, MySQL support, and enhanced Azure integration to boost your app connectivity.
App Model Enhancements: The updated Custom URLs feature lets you control whether URLs are shown on the resource page or the dashboard’s resource details page.
