CancelAfterBenchDemo

Benchmarking various ways to cancel tasks after some execution period

In this demo, i m using BenchmarkDotNet library in order to benchmark various ways of canceling tasks after some execution period.

1️⃣ UsingWaitAsync : a bench based on WaitAsync

2️⃣ UsingCancellationTokenSourceAsync : a bench based on CancellationTokenSource

3️⃣ UsingTaskCompletionSourceAsync : a bench based on TaskCompletionSource

4️⃣ UsingPollyAsync : a bench based on PollyPolicy

In order to run benchmarks, type this command in your favorite terminal : .\App.exe
