The Modern .NET Show

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.
Today's episode is another one without a guest; it's just me again. This is part two of the series I started at the top of the season, Bridging the Gap, and if you're wondering where part two got to, we had a standard episode in between. That'll keep happening. The series numbers and the season numbers are going to drift apart, and I'll say which part we're on every time so nobody has to do arithmetic..
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.

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.
Today's episode was recorded shortly before the annual mid-year hiatus, and was recorded live at Codegarden. Codegarden is Umbraco's main conference, and I was invited by the folks over at Candid Contributions to record a collaboration episode on one of the stages. We sat down to discuss the topic of AI-based contributions to open source, the opinions of everyone present, what the Umbraco leadership team (which Emma is a part of) throught of them, and the (then) recent news that rsync's developer had come under fire for using AI. Along the way, we took questions from the audience and the recording ends with a rather spicy opinion from me; so keep an ear open for that.
I'm very grateful to Emma, Lotte, Carole, and Laura for asking me to collaborte with them on this episode. I'd also like to thank everyone on the Umbraco team for organising everything and allowing me to be part of Codegarden.
One thing to note is that Carole's mic wasn't working in the openning minutes. Podcast editor superstar Matt has done what he can to clean the audio up, and Carole's mic got replaced at the three minute mark, but it's worth knowing that going in.
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.

Today's episode is a little different from the norm. There's no guest; it's just me. And it's the first episode of season nine, and the first episode of a series that I have apparently been meaning to make for about seven years without ever noticing that I was meaning to make 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.

Show Notes
"In the agentic world that makes a lot of people really uncomfortable because what ends up happening is the agent has it, the agent has its own ID and then interacts with your data database."— Jerry Nixon
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, Jerry Nixon returned to the show to talk about SQL MCP Server, something of a new product _and_ the evolution of Data API Builder; which we talked to Jerry about back in episode three of this season (there'll be a link in the show notes). Jerry does a much better job of introducing it than I can, but suffice it to say that SQL MCP Server is an MCP Server which abstracts away intracting with a SQL database... of almost any flavour. SQL Server, CosmosDB, Postgres, you name it.
"I mean there is nothing better for any agent than saying "new session." That is how you like create better answers all the time. You might feel like you have this session, you've been training it so long and you've told it so much, it has so much context that now when you ask it, it'll finally have the answer that you're looking for."— Jerry Nixon
Along the way, Jerry shared a lot of solid gold nuggets of advice about MCP servers, best practices for interacting with agents and models, and even context management. And, of course, we talk about how simple is almost always the best solution (and how SQL MCP Server might be one of the ways for you to achieve that).

Every contribution helps us continue bringing you these in-depth conversations with industry experts. You'll find all the links in the show notes.
So let's sit back, open up a terminal, type in `dotnet new podcast` and we'll dive into the core of Modern .NET.

Today's episode is a little different from the norm. I waned to, temporarily, take you away from the "AI is the best thing ever/worst thing ever" news cycle, and talk to you about an open source project that I work on called "OwaspHeaders.Core"
This is the second in a two-part series about OwaspHeaders.Core and focusses on providing a timeline of the evolution of the package; but this isn't going to a be all about how great I am. I'm going to cover the lessons I learned, the choices I made, and the help that I had from the community.
