I want to know about c# asyncronus programming

C# asynchronous programming lets your program do other work while it’s waiting for something slow (like downloading data or reading a file) instead of freezing and waiting.

use the keywords async and await make this work.

using System;
using System.Threading.Tasks;

class Program
{
static async Task Main()
{
Console.WriteLine("Start");

// Call an async method
await DoWorkAsync();

Console.WriteLine("End");
}

static async Task DoWorkAsync()
{
Console.WriteLine("Working...");
await Task.Delay(2000); // pretend to wait for 2 seconds (like downloading data)
Console.WriteLine("Work finished!");
}
}
