Welkom bij dag 2 van JetBrains .NET Days Online 2025! Duik in event-driven architecturen, GenAI met Semantic Kernel & .NET Aspire, F#, async/await, memory profiling en logging in de cloud. Leer van toonaangevende experts, ontdek nieuwe tools en technieken en kom in contact met andere #dotnet-liefhebbers. 👉 Volledige agenda & registratie: https://jb.gg/dotnetdays25-2 💬 Praat mee: #jbdotnetdays 👉 Bekijk de livestream van dag 1: https://www.youtube.com/live/Srsnb7JNXiw Hoogtepunten van dag 2 (9 oktober): 00:00:00 - Intro 00:03:40 - Change Is Inevitable: Versioning Event-Driven Systems door Laila Bougria. Praktische patronen om contracten veilig te laten evolueren – versiebeheer van berichten, upcasting en compatibiliteit zonder consumers te breken. 01:17:14 - Building Scalable GenAI Apps Using Semantic Kernel and .NET Aspire door Mehdi Hadeli. Orkestreer LLM-workflows met Semantic Kernel, koppel services met Aspire en schaal prompts, geheugen en gateways. 02:32:03 - Functional Programming in F#: Fad or Fabulous? door Ken Bonny. Waar FP uitblinkt in echte .NET-apps – pipelines, pattern matching, interop met C# en wanneer je het beter niet gebruikt. 03:46:25 - How We Found a 2 GB/Day Leak in 5 Minutes – dotMemory Meets Akka.NET door Aaron Stannard. Een debugverhaal uit productie – allocatie-hotspots opsporen met dotMemory in een actorsysteem met hoge doorvoer. 04:34:49 - Everything You (Don't) Want to Know About Async and Await in C# door Stefan Pölz. Diepe duik in contexts, deadlocks, cancellation, ConfigureAwait en beproefde patronen om responsief te blijven. 05:46:54 - Conquering Distributed Cloud Logging Without Breaking the Bank door Stathis Fylaktos. Kostenbewuste observability – logontwerp, sampling en opslagstrategieën die schalen zonder onverwachte rekeningen. 06:34:14 - Does GenAI Mean the Death of Test-Driven Development (TDD) door Johan Smarius. Wat verandert er en wat niet – hoe je AI-codegeneratie combineert met red-green-refactor en de kwaliteit hoog houdt. 07:39:43 - Outro Ondersteund door de .NET Foundation. #csharp #fsharp #dotnetaspire #unoplatform #blazor #jetbrainsrider #jetbrains

Practical patterns for evolving contracts safely – message versioning, upcasting, and compatibility without breaking consumers. 01:17:14 - Building Scalable GenAI Apps Using Semantic Kernel and .NET Aspire by Mehdi Hadeli. Orchestrate LLM workflows with Semantic Kernel, wire services with Aspire, and scale prompts, memory, and gateways. 02:32:03 - Functional Programming in F#: Fad or Fabulous? by Ken Bonny. Where FP shines in real .NET apps – pipelines, pattern matching, interop with C#, and when not to use it. 03:46:25 - How We Found a 2 GB/Day Leak in 5 Minutes – dotMemory Meets Akka.NET by Aaron Stannard. A production debugging story – identifying allocation hotspots with dotMemory in a high-throughput actor system. 04:34:49 - Everything You (Don’t) Want to Know About Async and Await in C# by Stefan Pölz. Deep dive on contexts, deadlocks, cancellation, ConfigureAwait, and proven patterns to stay responsive. 05:46:54 - Conquering Distributed Cloud Logging Without Breaking the Bank by Stathis Fylaktos. Cost-aware observability – log design, sampling, and storage strategies that scale without surprise bills. 06:34:14 - Does GenAI Mean the Death of Test-Driven Development (TDD) by Johan Smarius. What changes and what doesn’t – how to combine AI code generation with red-green-refactor and keep quality high. 07:39:43 - Outro Supported by the .NET Foundation. #csharp #fsharp #dotnetaspire #unoplatform #blazor #jetbrainsrider #jetbrains
