If you're an SME (Small to Medium Enterprise) leader wondering why your technology investments aren't delivering, or you're facing critical decisions about AI, modernization, or team productivity, let's talk. Show Notes "You actually cannot do proper vertical slice if you are bounded to controllers. Because there are some additional dependencies that you can download, like Ardalis [ApiEndpoints] or like Fast Endpoints that will give you actually what Minimal API is giving you. But with the standard controller-based approach you are not able to do the full vertical slice, because every time you'll need to take this, let's say presentation layer, outside your slice because it needs to be, just as you said, in the class that is inheriting from Controller and doing all the actions and stuff like this."— Kajetan Duszyński Hey everyone, and welcome back to The Modern .NET Show; the premier .NET podcast, focusing entirely on the knowledge, tools, and frameworks that all .NET developers should have in their toolbox. I'm your host Jamie Taylor, bringing you conversations with the brightest minds in the .NET ecosystem. Today, we're joined by Kajetan Duszyński to talk about some of the new things that are coming up in .NET 10. We cover some of the big things that you might have missed, some of the optimisations you can make by removing code (listen up for one in a few moments), and we also talk about his new book ".NET 10 Revealed." "So you all need to remember that if you are using Minimal APIs and you've used the extension method WithOpenAPI(), which created a proper OpenAPI schema. Right now it won't be used, so you'll need to delete every usage of this method from your whole application, because it will be um added by default in the pipeline of creating, of starting up the application."— Kajetan Duszyński Along the way we talked about allocations, the importance of learning MSIL (what your C# and F# code is compiled to), memory management, how fast .NET is moving and when we're likely to see the first public preview of .NET 11, and the vertical slice architecture. One of the biggest things that I think will cause some head scratching in .NET 10 is the new local self-signed TLS certificate. I've linked to an article by the folks at Duende about this, and it'll be worth adding it to your reading list. It's a great addition to .NET 10, but it'll catch some folks out.
