.NET Rocks!

ASP.NET Core continues to evolve in 2026! Carl and Richard talk to Daniel Roth about all the goodness in the ASP.NET Core space, including MVC, Razor, and Blazor! Daniel talks about the publicly visible ASP.NET Core Roadmap on GitHub - where you can support ideas, add your own, and debate implementations! The conversation dives into the focus on Blazor - MVC and Razor aren't going away anytime soon, or perhaps ever. Still, the energy is definitely on Blazor, and its potential to provide a great development experience that scales effectively and provides the features your applications need. And Daniel reminds us that the teams all work closely together, including the broader .NET and language teams, so new features are in the right place and available to everyone!

What does secure coding look like today? Carl and Richard talk to Chris Ayers about the MITRE ATT&CK matrix, a comprehensive breakdown of the tactics, techniques, and procedures black hats use to exploit your systems. Chris talks about the role of developers in creating more secure software, starting with logging - surfacing important data about the use of applications that can help indicate when a black hat is taking advantage of it. The conversation also digs into supply chain attacks, various techniques for resisting exploits being introduced through libraries, and the ever-expanding array of threats affecting software today!

Let the squad help you build your application! Carl and Richard talk to Brady Gaster about Squad, a tool for creating an AI development team using GitHub Copilot. Brady discusses creating specialist agents across various aspects of building an application to keep context as small as possible, along with token consumption. Often, agents communicate with other agents to work through project problems, generating persistent information about the project, including skills as needed. Squad continues to evolve and get more powerful - try it with your application!

Avalonia continues to evolve! Carl and Richard talk to Avalonia CEO Mike James & Matt Lacey about the latest version of Avalonia, the open source UI framework for building cross-platform applications with .NET. Mike's conversation with the Google Flutter team has led to replacing the Skia rendering engine in Avalonia with the newer Impeller Rendering Engine that Flutter itself depends on. This opens the door to excellent smartphone implementations with Avalonia, alongside its usual desktop and embedded roles. With enterprise editions and the new Avalonia Accelerate, there's more to come from the team!

Your first app interface should be a CLI! Carl and Richard talk to Kathleen Dollard about her experiences creating the .NET CLI - and how CLIs are only getting more important in the era of AI. Kathleen talks about working within the POSIX CLI standard for consistency's sake and to recognize that there will be many more CLIs in your life, so they should be as similar as possible. While CLIs may have started as configuration-as-code and DevOps practices, LLMs work well with them as long as consistency is maintained. There are several projects out there today to help you build a great CLI - check the links!
