Steve Sanderson

Most .NET apps can be made more powerful and productive through AI features, such as semantic search, auto-classification, summarization, translation, data extraction, and even chat-based assistants. But until now there's been no single standard representation for AI concepts within .NET itself, so developers needed to combine many unrelated APIs. Microsoft.Extensions.AI addresses this by providing a new set of standard APIs for AI services, including large language models (LLMs) running locally on your workstation or as hosted services, integrating with text embeddings, vector stores, and more. In this talk we'll demonstrate how these new standard abstractions let you combine multiple services that can easily be swapped and changed over time, and how you can plug into the internals for more advanced scenarios. By the end you'll be ready to start experimenting with new AI features in your own apps.

Your database objects are stored as code for development in Visual Studio or VS Code with Microsoft.Build.Sql SDK-style SQL projects, but the advantages don’t stop there. SQL code analysis and other build-time tests can validate database code quality and correctness during continuous integration of code changes. With SQL projects delivering database object updates is easier and more reliable whether you're managing one database or a fleet of databases because the deployment plan is dynamically calculated through the SqlPackage CLI. In this session we’ll learn how to develop and deploy your database alongside your app components with SQL projects from the IDE to CI/CD.

It is the age of AI and there are some big opportunities for .NET developers - infuse apps with solutions powered by Generative AI and Large Language Models (LLMs), as well as, boost developer productivity. .NET client apps can benefit from AI-powered Smart UI Components, like AI Prompts, Smart Grid/ComboBox search with Local Embeddings and searching/manipulating PDFs with Semantic search. Enterprise workflows often require working with desktop apps and document processing - rich text editing could make users productive with AI-powered completions, while spreadsheets could perform formulations/automations. Web developers could dynamically style web UI components with AI-powered theming or get contextual assistance while writing Blazor code in a browser REPL. Towards developer productivity, GitHub Copilot could be extended with custom chat agents to preserve developer context and get deeply contextual code completions, powered by documentation RAG. Let's explore what's next for AI-powered .NET UI towards wonderful UX and optimized developer productivity tools.

In the Star Wars universe, many pilots have an astromech copilot. Luke had R2-D2 in the back of his X-Wing for example. As developers, we too have copilots. Although these are not as cool as R2, and don’t help us blow up the Death Star, they do help us with our day to day tasks like writing code. Whilst copilots can be boring, Jim thought it would be fun to create one inspired by Star Wars to help him with important tasks, such as describing his Lego collection (Star Wars Lego of course), and helping him write code, all done in the style of a Jedi. In this session, Jim will walk you through the steps to build your own copilot, using the Pieces .NET SDK. By leveraging this SDK, your copilot can not only access an LLM of your choice from a range of cloud and on-device models such as Microsoft Phi and OpenAI GPT-4o, but you can also add assets to your chat’s context, such as code, documents, and plans for the Death Star. And just like a Jedi can sense the living force, this copilot can sense your presence and answer questions without needing additional documentation, such as summarizing your research on Wookiepedia. And best of all, reply like Yoda, it can! By the end of this session, you will be able to complete your apprenticeship and build your own open source AI copilot.
