DISTINGUISHED ENGINEER / MICROSOFT / .NET PLATFORM / VIEWS
01 / OVERVIEW

The tools under modern .NET.

A Distinguished Engineer whose frameworks sit underneath a huge share of production .NET - real-time, packaging, the web framework itself, and now distributed-app orchestration.

David Fowler is a Distinguished Engineer at Microsoft, working on .NET and ASP.NET Core. Over more than a decade he has created or co-created several of the most widely used tools in the ecosystem - SignalR for real-time web, NuGet for package management, and most recently .NET Aspire - and has been a core force behind ASP.NET Core itself.

His through-line is developer experience: taking hard problems - real-time messaging, dependency management, wiring up a distributed system - and turning them into something a developer can reach for without ceremony. Much of the framework ergonomics that .NET developers take for granted trace back to his design work.

With .NET Aspire, that focus moved up the stack to the shape of distributed applications - how you run, observe, and connect the many services a modern app is made of from a single, coherent developer workflow.
