This episode of The Modern .NET Show is supported, in part, by Avalonia XPF, a binary-compatible cross-platform fork of WPF, enables WPF apps to run on new platforms with minimal effort and maximum compatibility.

Yeah, exactly.

And it means you can, if you see it in its sort of native place, next time that you're writing something, maybe you don't go and change all your IEnumerables to IAsyncEnumerable because that's not worth doing. But maybe next time you're writing a new API you're like, "oh, you know what, I will use that newer API because it will give me better performance. And when I'm writing it, it's easy to just use the new thing and it's more applicable to this situation."

Welcome to The Modern .NET Show! Formerly known as The .NET Core Podcast, we are the go-to podcast for all .NET developers worldwide and I am your host Jamie "GaProgMan" Taylor.

In this episode, Andrew Lock joined us to talk about ASP .NET Core's new Minimal APIs paradigm. Along the We also talked about validation, and the third edition of his book "ASP .NET Core in Action" from Manning Publishing.

So it's sort of interesting, the philosophy, because obviously validation was one of the things they had some pushback.

In MVC You've got validation there by default, and clearly you always want to have validation of your arguments. So why didn't they include it in minimal APIs? And the answer basically is because there's more than one validation framework. There's the data annotation attributes... but then there's other frameworks like the fluent validation, for example, is a very popular one. And the only way that works in MVC is you have to sort of try and plug it in as an extra part and remove the old validation. And they didn't want to prioritize any particular style of doing validation.

So let's sit back, open up a terminal, type in dotnet new podcast and we'll dive into the core of Modern .NET.
