Setup

Add Semaphoria to your services:

builder.Services.AddSemaphoria();

Usage

Inject the ISemaphoreManager into your class:

public class MyClass(ISemaphoreManager semaphoreManager)
{
		public async Task MyMethod()
	{
		using (var semaphore = _semaphoreManager.GetSemaphore("MyKey"))
		{
			await semaphore.WaitAsync();
			// Do something
		}
	}
})

Extensions

If you want to skip processing rather than wait you can use the IsFull() method:

var semaphore = _semaphoreManager.GetSemaphore("MyKey")

if (semaphore.IsFull())
{
	// Skip processing
	return;
}
