Open source isn’t just for hipster stacks, learn how to build modern cloud-native apps with tools you’ll actually want to use. Today, .NET is fully open source—and when you pair it with PostgreSQL and Linux, you’ve got a modern, cross‑platform stack that’s built to last. In this demo‑packed session, we’ll show you how to build web and mobile apps with .NET, tap into PostgreSQL’s flexibility, and run everything on Linux containers. You’ll explore Npgsql, EF Core, and the new VS Code PostgreSQL extension, plus see how .NET Aspire makes deployments seamless across any cloud. If you’re looking for a stack you can bet on for the future, this is it.
