SignalR, Aspire, and No Kyber Crystals with Damian Edwards

In this episode, we catch up with Damian Edwards at Microsoft Build! We talk about his journey from launching SignalR to shaping .NET Aspire, how performance became a core .NET culture shift, and what it's like being in the room for some of the biggest moments in .NET history. He shares behind-the-scenes stories from the early days of ASP.NET, how Aspire is simplifying cloud-native dev, and even gives us his thoughts on lightsabers, Blazor, and Blu-rays. It’s a deep dive into code, performance, and a galaxy not so far away.
