🔐 Do you really understand ASP .NET Core authentication... or do you just know that it works?

If you've ever copied an AddAuthentication() setup and hoped for the best, you're not alone.

In the latest Update Talk, @WesleyCabus joins Chris Woody Woodruff to explain what's actually happening behind ASP .NET Core's authentication middleware.

From authentication schemes and handlers to cookies, tokens, and headers, this conversation helps connect the dots behind the code. Because sooner or later, every developer runs into that authentication bug that can't be fixed with another copy-paste from StackOverflow.

🎥 Watch the conversation, then dive deeper with Wesley's full session, "ASP. NET Core Authentication Explained," available on the Update NOW Portal: https://t.co/ymbzABkPy0

KEYNOTE SPOTLIGHT
What does it really mean to be a developer next year?

The role of developers is changing; but not disappearing.

In this keynote at #DEVintersection, @shanselman and @coolcsh (Scott Hanselman & Scott Hunter) ask the big question: What does it mean to be a developer next year?

💬 Will AI replace us? 💡 Or will it empower us to solve problems faster than ever?

Spoiler: Developers aren’t defined by their tools; they’re defined by their mindset. Whether it’s code, cloud, or Copilot, the mission remains the same: Find solutions, and build what matters.
