Smart UI Powered by AI 🚀

2024-11-16 01:30 -- 02:00

Sam Basu

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.

现在是 AI 时代，.NET 开发人员有一些巨大的机会 - 为应用程序注入由生成式 AI 和大型语言模型 （LLM） 提供支持的解决方案，并提高开发人员的工作效率。

.NET 客户端应用程序可以从 AI 驱动的智能 UI 组件中受益，例如 AI 提示、使用本地嵌入的智能网格/ComboBox 搜索以及使用语义搜索搜索/操作 PDF。企业工作流程通常需要使用桌面应用程序和文档处理 - 富文本编辑可以通过 AI 驱动的完成来提高用户的工作效率，而电子表格可以执行公式/自动化。Web 开发人员可以使用 AI 支持的主题动态设置 Web UI 组件的样式，或者在浏览器 REPL 中编写 Blazor 代码时获得上下文帮助。为了提高开发人员的工作效率，可以使用自定义聊天代理扩展 GitHub Copilot，以保留开发人员上下文并获得由文档 RAG 提供支持的深度上下文代码完成。让我们探讨一下 AI 驱动的 .NET UI 的下一步发展，以实现出色的 UX 和优化的开发人员生产力工具。

Deep dive on native AOT

2024-11-16 02:00 -- 02:30

Michal Strehovský

Native AOT has been part of .NET since .NET 7. With each release we're extending the areas where it can be used. From console apps in .NET 7, through ASP.NET web APIs in .NET 8, to MAUI in .NET 9. It is your best bet if you need your .NET app to start fast and use as little memory as possible.

But how does native AOT actually work? Why does it start so fast? How can we fit an entire .NET runtime, the base class libraries, and your code in a 1 MB executable file?

In this talk we'll peek into the internal workings of native AOT compilation and look at what it does at run time.

自 .NET 7 以来，本机 AOT 一直是 .NET 的一部分。对于每个版本，我们都会扩展其可以使用的区域。从 .NET 7 中的控制台应用，到 .NET 8 中的 ASP.NET Web API，再到 .NET 9 中的 MAUI。如果您需要 .NET 应用程序快速启动并使用尽可能少的内存，这是您最好的选择。

但是原生 AOT 实际上是如何运作的呢？为什么它开始得这么快？如何将整个 .NET 运行时、基类库和您的代码放入一个 1 MB 的可执行文件中？

在本次演讲中，我们将简要介绍本机 AOT 编译的内部工作原理，并了解它在运行时的作用。

The force is strong in LLMs - building an open source Star Wars inspired copilot in .NET

2024-11-16 05:00 -- 05:30

Jim Bennett

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.

在《星球大战》宇宙中，许多飞行员都有一个宇航机甲副驾驶。例如，Luke 的 X 翼后部有 R2-D2。作为开发人员，我们也有副驾驶。虽然这些不如 R2 酷，也不能帮助我们炸毁死星，但它们确实可以帮助我们完成日常任务，比如编写代码。

虽然副驾驶可能很无聊，但 Jim 认为创建一个受《星球大战》启发的副驾驶来帮助他完成重要任务会很有趣，例如描述他的乐高收藏（当然是《星球大战》乐高），并帮助他编写代码，所有这些都以绝地武士的风格完成。

在本次会议中，Jim 将引导您完成使用 Pieces .NET SDK 构建自己的 Copilot 的步骤。通过利用此 SDK，您的 copilot 不仅可以从一系列云和设备模型（如 Microsoft Phi 和 OpenAI GPT-4o）中访问您选择的 LLM，还可以将资产添加到聊天的上下文中，例如代码、文档和死星计划。就像绝地武士可以感知到生命力一样，这个副驾驶可以感知到你的存在并回答问题，而无需额外的文件，例如总结你在 Wookiepedia 上的研究。最重要的是，像 Yoda 一样回复，它可以！

在本次会议结束时，您将能够完成学徒期并构建自己的开源 AI 副驾驶。
