    "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. Whilst we didn't talk about anything that was super secret, things might have changed between recording the episode and you listening in.

    Building on .NET 10: A Chat with Kajetan Duszyńsk, Author of '.NET 10 Revealed'

    "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
    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.

    Hayden Barnes on .NET NES: Why We Need a New Approach to Open Source Maintenance

    "There's a good chance it's not gonna flag for you that, you, know your point of sale system is on .NET six and is now vulnerable, you know. So to a certain extent, companies often aren't even aware and this is something I've learned to be in this space. They're not aware. If they are aware, they know they need to upgrade. They're not sure, you know, when they're gonna find the resources, the time, the capital to upgrade"— Hayden Barnes

    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 Hayden Barnes to talk about HeroDevs and their Never Ending Support offering; a service where HeroDevs backport security fixes from later versions of dependencies, allowing companies to hold off on upgrading their important dependencies until they are ready to.

    "In some cases we simply hire the upstream developer or the upstream development team and they can continue to work on new features and the latest versions while maintaining the post-EOL versions and backporting those security updates. In some cases, we hire that library maintainer on contract."— Hayden Barnes

    Along the way, we talked about how the release schedule for .NET (one year per major release, with rolling support for up to 36 months) is a little to agile for some enterprise companies, and how HeroDevs can help. We also talked about how, where possible, HeroDevs actually hire the open source maintainers for packages to do the backporting, feeding funding back into the open source ecosystem.

    We also mentioned that this support doesn't just apply to post-end-of-life for versioned software. We also talk about the very unfortunate position where a developer is suddenly unable to support their work. An example that I bring up is previous guest on the show Jon P Smith, who in 2024 was diagnosed with dementia; meaning that at some point his libraries will need to be passed on to other open source developers. During the recording, I couldn't remember Jon's name, and for that I apologise. Jon has a very in depth blog post about the start of his journey with dementia called "How to update a NuGet library once the author isn't available." Please go read his blog post when you have the chance.

    "It's not just guessing. It's not just saying, "oh, there's something to log in. I think we'll call the button login." It actually knows the button is called Login, it's seen it. So that makes a big difference and makes it much more resilient. So that's definitely a big change, right? It's not just guessing. So definitely you should try it out."— Debbie O'Brien

    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 Debbie O'Brien to talk about both Playwright and the Playwright MCP server. We started with an introduction to Playwright, and talked about how both it and the MCP server for it can help you to automate both the writing and running of tests for your applications.

    Pro tip: If you've been using the Swagger UI in your applications, you've been using Open API.

    "And that's where the Playwright MCP comes In because it can automate a browser, it can basically go to the website, it can navigate, it can click, it can hover, it can do everything that you are doing in your tests."— Debbie O'Brien

    Along the way, we talked about how Playwright's MCP server can help you to find test cases that you might not have thought of initially. As a perfect example of this while recording this episode, Debbie found a bug in the app that I use to record episodes of the show, and talked about how Playwright MCP would help to recreate and debug the issue.

    It's worth pointing out that we recorded this in early August 2025, and that AI quite literally moves very rapidly. Whilst Playwright and MCP servers are not likely to change too much between recording the episode an when it went out, it'll be worth bearing that in mind as we talk about some of the AI stuff.

    Building the Future of APIs: Mike Kistler's Insights on OpenAPI and MCP

    "And we talk about that contract. We say, "this is your contract. This Open API definition that you have is the contract for your service." 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 customers know how things work, how to use them, hopefully how to use them easily, right?"— Mike Kistler

    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 Mike Kistler to talk about two topics (we usually only tackle one topic per episode, so you're getting a bonus with this episode): Open API and both MCP and the MCP SDK for C#.

    We started our conversation by focussing on Open API, as this is a passion of Mike's. We talked about what it is, how you've likely already been using it with any ASP .NET Core WebAPIs that you've worked on, and how the latest versions of ASP .NET Core can generate a lot of the Open API specification for you without having to add lots and lots of metadata an attributes.

    Pro tip: If you've been using the Swagger UI in your applications, you've been using Open API.

    "And when the LLM decides that it wants to use an MCP tool or access an MCP resource, it doesn't go and do that directly. It comes back to the MCP host and asks the MCP host to call a tool with a particular set of parameters, or to access an MCP resource. And at first, when I saw this in the MCP architecture, I thought, "boy, that's clunky. Why not have the LLM just call these things directly?" And there's a deliberate reason why it was done this way."— Mike Kistler

    We then pivoted over to talking about MCP (or Model Context Protocol) which is a rapidly evolving standard for creating your own agents and applications which can communicate with or be instructed by, LLMs. We talked about how the MCP standard works, and how the standard is written in such a way that there's always a human in the loop. We also talked about how you can build your own MCP servers using the MCP SDK for C#.

    It's worth pointing out that both MCP and Open API are evolving standards. While Open API tends to evolve with a much more relaxed pace, the MCP standard (having not even reached a year old when we recorded) uses the date as it's version number. And Mike actually references the latest version of the MCP spec in our conversation, which will give you a clue as to when we recorded it.

    "What do I mean by compute? Compute is whenever you want a computer to do a thing, okay, it requires the CPU to exist and I want the CPU to do a thing. 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 chip. So, if you have an NVIDIA chip, it does a lot of really good things, but as we know, they're very expensive, and that's why NVIDIA is like what, I guess, the largest company in the world right now."— Michael Washington

    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, Michael Washington joined us to talk about his open source project "Personal Data Warehouse", what a data warehouse is, and the why we collect data in our applications. We also talk about the differences between storing data in the database and storing it in a data warehouse—one of the biggest differences, as you'll find out, is the difference in cost.

    "The only reason why we collect any data is because at some point a human being needs this data to make a decision. Seriously, and I challenge anyone to come up with any exceptions to that."— Michael Washington

    Along the way, we talked about the benefits and pitfalls of leveraging AI (particularly LLMs) in your applications. Both Michael and I agree that there is little "intelligence" in LLMs in the traditional sense, and Michael brings up the most important point when deciding to an LLM in your application: that a human must always make decisions based on what data they have and what the LLM can provide. We must never hand over decision making to LLMs.

We talk about Safia's journey in development, what it means to work entirely in the open, and what it's like to read through and triage issues on the ASP .NET Core repo.

    "I have certain people in my open source career who I have met and interacted with on a number of different projects, And the ones that stand out as great mentors and role models for me were people who were so good at creating psychological safety in open source spaces so that people could present their ideas. And they were really good at uplifting other people's ideas and pushing them further."— Safia Abdalla

    We also talk about the importance of interpersonal skills in modern software engineering (whether you're working in open source or not), psychological safety, and the importance of self-reflection in our day-to-day work.

    Before we jump in, a quick reminder: if The Modern .NET Show has become part of your learning journey, please consider supporting us through Patreon or Buy Me A Coffee. Every contribution helps us continue bringing you these in-depth conversations with industry experts. You'll find all the links in the show notes.

    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.

    Umbraco Unplugged: Emma Burstow & Mats Persson on Umbraco Being The Friendly, Truly Open-Source, CMS
    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

    "From the first engagement with any from Umbraco, it's been a friendly approach. We are friendly. It's a part of our DNA. Professional. We take our work dead seriously, but we want to have fun, but we are friendly."— Mats Persson

    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, both Emma Burstow and Mats Persson of Umbraco are here to share their expertise on building Umbraco—a completely open source CMS, known as the friendly CMS. Emma is Umbraco's Director of Developer Relations and Mats is their newly appointed CEO.

    "One of our values is openness. And once again, I'll say we really walk the walk. So we alert people early. We work in public, truly. We don't just, you know, update things on git as in terms of code. We write words around it. We have discussion boards We have ongoing issues that are open, and we talk to people that are working with the product"— Emma Burstow

    We also dive into what it's like to build Umbraco completely in the open, which led to some fascinating insights into how to build and manage a world-wide community of contributors, but also how to help manage expectations of those developers and technologists.

    Learning Azure with Jonah Andersson: A Developer's Guide to Cloud Computing and Development Fundamentals
    RJJ Software's Software Development Service

    This episode of The Modern .NET Show is supported, in part, by RJJ Software's Software Development Services, whether your company is looking to elevate its UK operations or reshape its US strategy, we can provide tailored solutions that exceed expectations.

    Show Notes

    "So the cloud adoption framework actually has a lot of steps for organizations or IT teams to start assessing their existing environments first and planning the stage before they modernise and migrate to Azure. And then the well-architected framework allows the team, whoever is involved, developers, engineers, or architects, working in that migration project to think how they're going to think about architecting for the cloud in a way that it meets all the pillars in terms of resiliency, performance, architecture, and everything. Security, for example, that they need to think about."— Jonah Andersson

    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, which is the final one of season 7, Jonah Andersson joins us to talk all things Azure, the many pathways involved in migrating and modernising .NET applications, and publishing to the cloud.

    "So one tool that I actually highly recommend when it comes to .NET, there is a plug-in for Visual Studio, actually, for .NET, and even, I think, with Java. There';s a tool called AppCAT plugin, and it's like a modernization tool that is part of the Azure Migrate that allows .NET developers who are ever working in a migration project with .NET, that they can add a plugin in Visual Studio and they can assess their existing source code, .NET source code, based on the well-architected framework, if it's ready or not, or there are gaps in the code."— Jonah Andersoon

    Along the way, we talk about Jonah's podcast "Extend Women in Tech Podcast" (which I would highly recommend), and her book "Learning Microsoft Azure: Cloud Computing and Development Fundamentals" and why she chose to write it.

    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.
