High Performance .NET Development
.NET 9.0 is fast. The modern, cross-platform .NET and ASP.NET Core are highly optimised, enabling incredible performance across desktop and web applications. But to take the best advantage of this underlying power, your code needs to be optimised too. Writing code with performance in mind makes your application more responsive for users, and can lower hosting costs for cloud-based deployments.
This workshop covers:
- Using BenchmarkDotNet to test and optimize algorithms
- Load-testing Web APIs and sites
- Exploring performance during development using the .NET Aspire tools and OpenTelemetry
- A grab-bag of performance tips and tricks that can be applied to any .NET solution, from low-level optimizations to simple configuration changes
Requirements
Attendees will be expected to be familiar with .NET and C#.
Computer setup
- .NET 9
- Your preferred IDE or editor
- Docker Desktop (or Rancher or Podman)
