Hello Shiva, You can use Task.WhenAll() as below in realtime. using System; using System.Threading.Tasks; class Program { static async Task Main(string[] args) { // Call three asynchronous methods concurrently using Task.WhenAll await ExecuteAsyncAllMethods(); } static async Task ExecuteAsyncAllMethods() { // Start three asynchronous tasks Task task1 = Test1Async(); Task task2 = Test2Async(); Task task3 = Test3Async(); // Await all tasks to complete using Task.WhenAll await Task.WhenAll(task1, task2, task3); // Retrieve results from completed tasks int result1 = await task1; string result2 = await task2; bool result3 = await task3; // Output results Console.WriteLine($"Method 1 result: {result1}"); Console.WriteLine($"Method 2 result: {result2}"); Console.WriteLine($"Method 3 result: {result3}"); } static async Task Test1Async() { await Task.Delay(2000); // delay operation by 2 second return 10; } static async Task Test2Async() { await Task.Delay(1000); // delay operation by 1 second return "Hello"; } static async Task Test3Async() { await Task.Delay(6000); // delay operation by 6 seconds return true; } }

Hi jignesh, I called the 3 methods as like you mentioned but second and third methods are executed and returned the result Without first method returned the results It is not waiting all the methods get executed

In above example that is use for testing purpose because we want to wait until all task completed. Our case after 6 seconds all methods should execute. In your case just need to add all methods as task and call like my example should work. Could you please share your code so can check on that?

Hi jignesh, Why we are adding Tas.delay() in each and every method May I know the use case If we are not using that delay what will happen
