This talk is a practical guide for engineers looking to port .NET services across architectures, particularly toward ARM-based platforms, to unlock energy efficiency and performance gains. We’ll walk through the real-world journey of moving services from traditional x86 and x64 to ARM, highlighting the common roadblocks and how to overcome them. This session is not just about theory—it’s a how-to for engineers who want to make their services greener without sacrificing quality or velocity. Whether you're working on microservices, APIs, or backend systems, you’ll leave a notion of what to watch out for and a clear understanding of the potential wins—both for your service and the planet.
