UmbLondon March 2025 - talking null handling and more!

We're excited to announce a new venue for this month's meetup: Umbraco Platinum Partners This Is Embrace near Borough Market. Doors open at 18:30 for a 19:00 start, and we'll head to the pub at 21:00 to continue the conversation over drinks.

"System.ArgumentNullException: Value cannot be null. Parameter name: sessionTitle"
by Jason Elkin, Bump Digital

The inventor of the null reference calls it his “billion dollar mistake” and for years we’ve suffered crashes, vulnerabilities, and wasted so much time debugging the dreaded null reference exception. Modern C# has a solution to this problem, one of my favourite features: nullable reference types. In this talk, we'll explore how nullable reference types can enhance the resilience and expressiveness of your code, helping to significantly reduce the likelihood of null reference exceptions - potentially eliminating them altogether! We’ll look at the often misused null-conditional, null-forgiving, and null-coalescing operators with real-world examples of how best to use them in an Umbraco project. Finally we’ll look at some strategies for introducing nullable reference types to your codebases, and your teams, in a way that increases code quality and improves your team's performance.
