This episode is a super important, top-of-the-heap, bonus episode that you definitely need to be listening to. I, basically, reached out to Hayden Barnes, who we've just now had on the show to talk about .NET never-ending support and what happens when you drop out of support with Microsoft....

So that makes a big difference and makes it much more resilient. So that's definitely a big...

And in the end, that's how customers interact with Azure is through APIs. And so it's important to have that contract so that...

How well it can do it Is based upon what kind of CPU you have. What kind of CPU they have since have it in miniature...

Show Notes
"I remember I had the entire life cycle of the web forms printed on a wall. It was like six sheets of paper and it was very complex, and it was very useful to have it on the wall because, like, you could always look at it and say, "okay, this is going on before this one." So you have to like switch the order of things. But that's exactly what I call interesting"— Tomáš Herceg
Welcome friends 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. We are the go-to podcast for .NET developers worldwide, and I am your host: Jamie "GaProgMan" Taylor.
In this episode, we talk with Tomáš Herceg about strategies for modernizing .NET Framework web applications such that they leverage the very latest in the .NET stack. Tomáš shares his insights from the journey of upgrading his own applications and those of his clients, both of which provided the background for his new book: "Modernizing .NET Web Applications".
"The biggest problem of the YARP migrations: that they will force you to do a lot of infrastructure things at the beginning before you even start migrating some real functionality."— Tomáš Herceg
Along the way, we discuss how using his DotVVM project can help with the migration. Not only is the upgrade path for DotVVM projects a process of swapping a NuGet package, but is also keeps the upgrade as a single in-memory process—something that YARP-based migrations aren't able to do.
Anyway, without further ado, let's sit back, open up a terminal, type in `dotnet new podcast` and we'll dive into the core of Modern .NET.
