  • The Paper Cuts Microsoft Actually Fixes: A Deep Dive into .NET 10 with Mark J Price
    Feb 20 2026
    Strategic Technology Consultation Services This episode of The Modern .NET Show is supported, in part, by RJJ Software's Strategic Technology Consultation Services. 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 "There's so much that we can talk about with. NET 10 and related things like C# 14. So I'm going to try and focus on a few of the highlights that are personal highlights for me So let's start with the language actually, C# 14."— Mark J Price 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 Mark J Price to talk about some of our favourite things in .NET 10 and his new four-part book series on, quite literally, everything .NET. Mark is one of the most prolific authors in the .NET space at the moment, and his new book series is shaping up to be a fantastic resource. "One of the things that I've always appreciated with Microsoft and their culture is that they have a very strong requirement that thing things are as backwards compatible as possible."— Mark J Price Along the way, we talked about the recent changes to the STS (aka Standard Term Support) lifecycle for .NET, brining more support to the odd numbered versions of .NET and giving companies more time to migrate from one version to the next. We also covered a very important point when it comes to either STS or LTS towards the end of the episode: essentially, keep your runtimes up to date, folks. This episode marks the fifth appearance of Mark on the show. Mark has been a wonderful collaborator over the years, and long may that continue. We joke about the fact that Mark deserves an award for the guest with the most episodes, but maybe he does deserve an award. Unless someone out there is willing to beat his record, of course.

  • Jody Donetti on Creating FusionCache and Collaborating with Microsoft on HybridCache

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 "The idea is that you get you have some sort of source. It's called usually the single source of truth, which is usually a database. In the case of web caching is the remote server that is the authoritative uh source of truth."— Jody Donetti 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 to talk about FusionCache, caching in general, and what in-memory, distributed, and hybrid caching are. Note: hybrid caching ins't the same as the Microsoft library HybridCache. "That's the first problem. The second problem is that by using a distributed cache directly, you pay the price of network calls and deserialization every single cache call that you make."— Jody Donetti Along the way, we talked about open source development, how Jody got started with working in the open, and that listeners should never be scared of working in the open. If you're building something for fun or to learn (rather than to give back or create the next big open source library), then let people know in the readme.

  • BONUS: Jamie's Appearance on Coder Radio 640 - GitHub's Spec-Kit
    Feb 2 2026
    Show Notes

    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. This episode is a slight departure from the standard episode format, as it's a snippet of an episode of Code Radio.

    I was invited to discuss GitHub's SpecKit on Coder Radio as I'd been talking about it on the Discord server for the show for a while and really believe in it's transformative power as one of the better Coding-with-AI frameworks.

    During the episode, I brough up ClawdBot which immediately aged the episode. Clawdbot has gone through two name changes since the episode was recorded and this bonus episode was released: first to MoltBot then to OpenClaw.

    Another thing to note is that, since the episode went live Michael has opened up his Code for Climate 2026 — The Mad Botter Earth Day Open Source Challenge for anyone in K-12 and college education. So if you know folks who would be interested, send them the link. There are some amazing prizes up for grabs, including a couple of System76 computer systems and even a paid internship at The Mad Botter Inc.

    Anyway, let's get to the episode.

  • From Chaos to Control: Anton Moldovan on Load Testing with NBomber
    Jan 23 2026
    Strategic Technology Consultation Services This episode of The Modern .NET Show is supported, in part, by RJJ Software's Strategic Technology Consultation Services. 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 "Another thing which I also observed is that there is some benefit to be able to run your load test in your native... using your native platform, libraries, protocol access; those type of things. Because in our case, for example, we use Orleans and it's a proprietary protocol which doesn't exist in in Java in Scala language. The same about, almost the same, was about Signal R: Microsoft released SignalR for Java, but the quality of this library was different."— Anton Moldovan 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 Anton Moldovan to talk about load testing, advice for testing strategies, and how NBomber can help you to load test your applications. Are you sure that your application can handle 4 million users at once? Better load test it before you start boasting. "We call this type of test, like, "user journey." Like, end-to-end simulating user journey across entire applications. So end-to-end, end-to-end flow, end-to-end tests. But this type of test they they have some downsides."— Anton Moldovan Along the way, we talked the different types of testing involved in getting your application for production, the many different ways that NBomber (or other load testing suites) can help you prepare for that, and Anton helps us understand a little more about functional programming.

  • NDepend with Patrick Smacchia: Scaling .NET Code Quality
    Jan 9 2026
    Strategic Technology Consultation Services This episode of The Modern .NET Show is supported, in part, by RJJ Software's Strategic Technology Consultation Services. 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 "So the interest plays a lot of a huge role. Like for example a security issue, it can take you maybe half a day to fix, or maybe one hour to fix; so it's very easy to fix. But if you don't fix it, you get so... you'll get so many angry users that it may be, it maybe, it will cost you your entire business; you see. So this can be seen as an interest."— Patrick Smacchia 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 Patrick Smacchia to talk about NDepend, technical debt and the interest it accrues (something that's often forgotten about), and how NDepend can help you to keep your tech debt (and it's interest) low. "But the thing we see is that the edge code is usually the code where you get the bugs. So you end up writing some quick tests that can cover 90% of your code, but your 10% here is not tested. And because it's not well implemented and it's likely to contain the bug. So, maybe you should refactor your code and make your class testable."— Patrick Smacchia Along the way, we talked about the common pitfalls that most developers make when writing code, and how to keep your code both testable and easy to maintain. We also took some time to talk about bug reports, the things that you and I can do to ensure that our bug reports are read, providing positive feedback, the Visual Studio teams' velocity, and some of the amazing new features in Visual Studio 2026 like the ... well, I'm getting ahead of myself. You'll have to listen in to the episode to find out what those features are.

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 "And the first feature we have that take advantage of this deep integration is the Profiler Agent. And this is absolutely bonkers. So you can simply go to the chat window in Visual Studio and you can ask…"— Mads Kristensen 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 Mads Kristensen to talk about all things IDEs, tooling, and the new functionality that Visual Studio 2026 (aka "Dev 18") includes and how it has the chance of greatly impacting your development practice, in a fantastic way! "And we want to make sure that You know, we we do as many of those as we can. We want to remove those paper cuts, make you as happy as possible. And so if you look back at the last 12 months, we have of you know of all the bugs people have opened on us, we fixed almost 4500 user-reported bugs. That's 18 bugs that we fixed every single work day."— Mads Kristensen Did you know that Mads was present for what many see as the inciting incident that lead to .NET being both open source and cross platform: when jQuery was bundled with ASP .NET Framework and Visual Studio.. We also took some time to talk about bug reports, the things that you and I can do to ensure that our bug reports are read, providing positive feedback, the Visual Studio teams' velocity, and some of the amazing new features in Visual Studio 2026 like the ... well, I'm getting ahead of myself. You'll have to listen in to the episode to find out what those features are. It's also worth noting that I recorded this podcast with Mads back in late August 2025, which was way ahead of the public preview of Visual Studio 2026.

  • Building on .NET 10: A Chat with Kajetan Duszyńsk, Author of '.NET 10 Revealed'
    Nov 28 2025
    Strategic Technology Consultation Services This episode of The Modern .NET Show is supported, in part, by RJJ Software's Strategic Technology Consultation Services. 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.

  • Hayden Barnes and CVE-2025-33515
    Nov 21 2025
    Show Notes 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. 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. The reason that I did that, and the reason that this intro is so raw is because we talked about what is known as "the worst CVE for the internet as a whole. If you want to Google it while we're talking right now, look for "CVE 2025-55315". We'll get into it in a moment, but pretty much everything on the internet is susceptible to this, and only .NET 8, 9, and 10 have a fix. Nothing else has a fix in the. NET space. You will find out in this episode what it is, what problems it can cause you, and how to solve those problems. Please stick around and listen, folks. Thank you, Matt, the editor, for putting this together so quickly. Anyway, on with the episode. I'm not even going to do the dotnet new podcast thing. It's that important.
