**Let's escape the hustle and bustle of Jakarta with a late afternoon stroll through Senayan GBK Park and make some new friends along the way!** Senayan GBK Park is located in the heart of the city and is a nice place to visit and explore. Starting from Entrance 7 (Pintu 7), we will walk around and through the park and then over to Senayan Park Complex. Afterwards, we'll go to Lucy in the Sky at Spark, located on the rooftop of Senyan Park Mall for some refreshing drinks and food. This last part is optional for people who want to go. The walk will be a casual stroll around several connecting parks. The walk will take approximately 1:30 hours. We will meet just outside Entrance 7 near the main road. Please be on time, as once we start the walk it will be very difficult to locate us. However, we will post the live location on the WhatsApp Group chat. This is a fun and social event, and everyone is encouraged to get to know each other and make new friends. **📢 IMPORTANT: Attendance Reconfirmation Required** To ensure accurate headcounts and reduce no-shows, we're implementing an updated reconfirmation system for all events. **Here's how it works:** * All events start with unlimited RSVPs. * 4 days before each event, a reconfirmation form will be posted in the event comments and shared in the WhatsApp group. * You must reconfirm ASAP by submitting the form.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA
