The Aspire 13.6 dashboard now uses Native AOT 💫 That means 66% faster median page-visible startup and no separately installed .NET runtime for the native dashboard executable. @JamesNK walks through how the team got there: devblogs.microsoft.com/aspir…

Bringing Native AOT to the Aspire dashboard

Aspire 13.6 brings Native AOT to the dashboard. Explore the startup and deployment benefits, plus the Blazor, Fluent UI, JSON, and Dapper changes that made it possible.

Aspire 13.6 features, day 6 The dashboard lets you pause incoming telemetry so you can focus on the telemetry you already have. But it's important to know when the pause is active. The pause notification is now consistently displayed across all pages 👀

Aspire 13.6 features, day 4 The Aspire logo and purple in the dashboard were wrong 🚨😱☠️ Due to historical reasons, the colors and logo were close , but not the same as official Aspire branding. Literally unusable. This critical issue was immediately prioritized and fixed 💜
