.NET Rocks!

What do Domain-Driven Design and event sourcing have to do with each other? Everything! Carl and Richard chat with Anita Kvamme about her experiences applying DDD, and specifically event storming, to developing applications using event sourcing. Anita talks about building applications that have many sources of events—from users and elsewhere—and needing to manage that complexity without slowing down development. Event sourcing also means keeping a source of the truth - all events leading up to a practical business benefit. And that can be hugely helpful in analytics as well!

How can a low-code solution help you deliver a .NET app? Carl and Richard talk with Serge Sarafudinov about his Xomega project. Serge describes how Xomega uses models and templates to generate .NET code for applications for Blazor clients, WPF, and even ASP.NET Forms and TypeScript! The conversation also digs into rehabilitating existing .NET applications where new features can be added with Xomega, and then gradually convert the existing application into the model approach - and then you can change out the client if you like! There are free and paid versions of Xomega; take it out for a spin and see if you can't deliver solutions faster!

How do you manage APIs to GenAI, and how can GenAI help with API management? Carl and Richard chat with Andrei Kamenev about the latest features coming to Azure API Management. On the one hand, there are Copilot tools to help craft and understand APIM policies, which can get very complex. Then, there is the provisioning of access to GenAI-related APIs like the Azure OpenAI service, which utilize tokens - and those tokens mean money, so they need to be controlled. The GenAI Gateway provides the ability to rate-limit token issuing and all the other capabilities you expect from APIM. Prompt caching is in preview and can decrease the cost of repeated use of the same prompts. Many of the features are new, and more are coming!

How can .NET Aspire help you get into containers? Carl and Richard talk with Jiachen Jiang about her experiences working with .NET Aspire. Jiachen talks about the power of .NET Aspire to help lead developers to utilize cloud native architecture efficiently. A key part of the equation is containers, and Jiachen talks about how relatively rare containerized .NET apps are - because in many cases, it doesn't add anything but complexity. But as .NET applications need to scale in the cloud, containers become important, and .NET Aspire helps you to take advantage of containers while adding all the cloud-native features you'll value, like great telemetry, orchestration, and discovery!

What if you want to build your own copilot? Carl and Richard talk to Vishwas Lele about his new startup, which is focused on using Azure OpenAI tools to help automate the government RFP writing process. Vishwas discusses the complexities of proposal writing, how specific and complex rules exist for each part of the proposal, and the challenge of getting the software to do an excellent job on the draft. The conversation digs into the domain expertise needed for the technologies and the proposal writing itself - like all good software, it requires domain experts. But when done right, this is hugely valuable software!

What are the basics of building a decent user interface on a web page? Carl and Richard talk to Hilary Stohs-Krause about her experience helping folks build websites - you don't have to be a designer to make something useable! Hilary talks about steering clear of more complex UX libraries unless you know the site owner prefers them. Keeping things simple and consistent is best! The conversation also digs into accessibility and how accessibility needs are a great guide to a decent basic design - making a site that can help everyone understand the pages you've built a great path to a very useable website.

What's happening with WPF? Carl and Richard talk to Joseph Finney about the news from Build about WPF - it's back, baby! But did it ever go away? Joe talks about how WPF was made open source in 2018 and how minimal development was done there - enough so that the community started building frameworks to support it, including WPFUI and ModernWPF. But at Build, Microsoft announced a new focus on WPF, including creating support for a Windows 11 theme - with a line of code, you can make your WPF app look like a Windows 11 app. Where does this leave WinApp SDK? What about migrations? There's lots to talk about!

Multi-modal is here and ready to use! Carl and Richard talk to Veronika Kolesnikova about what she has seen in the latest OpenAI model. Multi-modal refers to GPT-4o's ability to work with text, audio, images, and more and respond in kind! Veronika talks about tackling interesting visual problems with GPT-4o - like summarizing graphs or creating new data visualizations. The conversation digs into some announcements around Build, including the new security features in AI Studio and Windows Recall in the new Copilot+ PC devices. Things are moving quickly!

CosmosDB makes ChatGPT fast! While at Build in Seattle, Carl and Richard chatted with Mark Brown about CosmosDB's role in AI. Mark talks about how ChatGPT switched over to CosmosDB early on - when the number of users started to climb, database performance became essential, and CosmosDB was there. Today, many AI-centric CosmosDB features exist, like vector storage, indexing, and search! The conversation also digs into the impact of the large language model on development - things are different now!
