| Chasing performance in the world of dotNET. | Does performance optimization matter in the dotNET era, or is the JIT compiler as good as it gets? Can I use one data structure for everything? What are the performance implications of various choices? Let's find out in this talk! |

| Vibe Coding and Sofware Quality | The world of software development is constantly changing. The introduction of AI assistant has accelerated the speed of which these changes occur rapidly. New AI tools are announced on a weekly basis, and it sometimes seems that the traditional “coding” became old-fashioned, like vinyl records or VHS tapes. Although that’s definitely not the case, there can be no doubt that software development in the year 2026 is radical different from software development a few years ago. Development with X# is no exception. One of the new term developers talk a lot about worldwide is called Vibe Coding. Vibe Coding means writing code in a way that keeps you in the flow: fast feedback loops, readable structures, clear naming, and a development rhythm that makes daily work more enjoyable. Surprisingly, X# offers a lot of opportunities to code with a great vibe, especially for developers coming from Visual Objects or another xBase language. The development is done with Visual Studio but with the help of an AI assistant like *CoPilot*. But it does not have to be *ChatGPT* or another commercial LLM. It can be a LLM that runs locally as well. And in contrary to some believes, Vibe Coding is not a concept for writing programs from scratch with no or little intent to actually code. It’s also very well suited for improving existing code, no matter how old it is. Through practical examples, small patterns, and a live refactoring demo, we’ll explore how to make X# code easier to understand, maintain, and extend — without adding unnecessary complexity. This session is for developers who want their code to be not only correct, but also pleasant — code they’re happy to return to weeks or years later. |

| Read/Write to your tables with typed Linq queries and typed POCO objects | This session presents some work based on IQtoolkit, writing an ADSProvider. Basically it's a LinqToSQL library that uses Advantage ADO.net provider and some specific code for ADS SQL that opens you the magical world of IQueryable<T> With that you can read/write into your DBFiles with typed Linq queries ! Selecting data with provider.GetTable<ClassName> gives you an IQueryable<ClassName> which basically opens you all the doors to all the IQueryable compatible components. In our project it gives us the ability to use DevExpress grid controls LINQ DataSource with all the bells and whistles it brings (grouping, filtering, summing, paging, virtual scrolling, ... ) The provider supports associations, lazy loading, native scalar function translation (Convert.ToInt32(column) becomes VAL(column)), composite DateTime manipulation. And because the Advantage SQL engine is so well written, it will even use the indexes it can detect based on the where clauses. And because ADS gives us a library (adsloc32.dll) to "emulate" a remote server, you can use all that with DBF/CDX direct file access !! Well there are so many things to cover, if you (and the XSharp community) are interested ! For now it's in a beta stage, we're using it in pre-production for our webapi projects. It specifically supports DBF/CDX (and all its limitations, likes Dates only, no FK, no PK, etc..) and can be extended to unleash the power of VFP and then ADT ! |

| XSharp Advanced Tips and Tricks | Chris will demonstrate the new features in the XSharp 3 compiler and will show some advanced topics on how to use XSharp to improve the performance of your applications. |

| a WPF framework to build WPF applications in X#, using MVVM and databinding | Wolfgang uses a code only approach to write WPF applications. He will demonstrate this in this session and explain how MVVM and databinding work. |

| Adding AI to your apps with X# | This session shows how to integrate Large Language Models into X# applications using practical, provider-agnostic patterns like ReAct, sliding context windows, and lightweight RAG, all implemented in pure X# Core. You'll see a live demo of an XIDE plugin that safely assists with legacy code modernization, without overwriting your code or relying on magic. This is AI as software engineering, built for developers who value control and reliability." |

| Move your apps from .Net Framework to .Net Next |
XSharp 3 comes with support for .Net 8,9,10 and for the new SDK projects that are needed to build these apps with MsBuild |
