Learn how to protect yourself and your family from scams and fraud - don't fall victim to con artists! **Elder Fraud Prevention 101** Join us at **507 7th St, Laurel, MD 20707, USA** for an informative session on how to protect yourself and your loved ones from scams targeting seniors.

It impacts their financial security, mental health, and overall well-being, often leaving them vulnerable and unable to meet their basic needs, while also causing significant emotional distress and a potential loss of independence; therefore, actively preventing and combating elder fraud is essential to protect the most vulnerable members of society. This workshop will provide valuable insights into elder abuse scams, common tactics used by criminals, and ways to prevent victimization. It will also discuss possible steps to take AFTER an elder fraud or scam has occurred.

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
