Just a simple performance benchmark that I created for fun to compare the performance of several .Net API client library using BenchmarkDotNet.
- Created simple Api application using .Net Core and host it in local IIS.
- Created Benchmark and point it to said API.
- Magic.
- WebRequest
- HttpClient
- WebClient
- RestSharp
- Flurl
