Thread synchronization is not important to me. I just want to understand if there is any specific difference.
So can someone review this code and give me some ideas. All methods are executed in the background as desired I just

Part 1.

In Program DoSomeAsyncStuff() when removed async then

Task.Run(() => DoSomeAsyncStuff("a")); will block the execution, so I need async,

Compare DoSomeAsyncStuff to DoSomeAsyncStuffV2 is once implementation preferred over another?

UPDATE: Let's focus on

Part 2.

whats the difference private async Task Do..() vs private Task Do..()
based on this https://stackoverflow.com/a/48392684/1818723 I think there could be none, but if you look at both methods implementation, one is awaiting for task to complete and the other is returning the task

public class ServiceX

{

    public Task SomeServiceEntryMethod()

    {

        Console.WriteLine("Multithreading started");

        Thread.Sleep(1);



        List<Task> tasks = new List<Task>();

        for (int i = 0; i < 8; i++)

        {

            //I can use this version 

            //var t = DoSomeAsyncStuff(i.ToString());       



            //or I can use this version both seems to have same results

            var t = DoSomeAsyncStuffV2(i.ToString());

            tasks.Add(t);

        }

        //in the calling method I can await for all task to complete the for loop spins a few async tasks

        return Task.WhenAll(tasks); 

    }



    private async Task DoSomeAsyncStuffV2(string text)

    {

        await Task.Run(() =>

        {

            if (text == "0")

                Thread.Sleep(1000);

            Console.WriteLine("test " + text + " " + Thread.CurrentThread.ManagedThreadId.ToString());



        });

    }



    private Task DoSomeAsyncStuff(string text)

    {

        return Task.Run(() =>

        {

            if (text == "0")

                Thread.Sleep(1000);

            Console.WriteLine("test " + text + " " + Thread.CurrentThread.ManagedThreadId.ToString());



        });

    }

}



class Program

{

    public static async Task Main(string args)

    {

        //Task.Run(() => DoSomeAsyncStuff("a"));

        //Task.Run(() => DoSomeAsyncStuff("b"));



        //DoSomeAsyncStuffV2("c");

        //DoSomeAsyncStuffV2("d");

        ServiceX x = new ServiceX();

        await x.SomeServiceEntryMethod();

    }



    //private static async void DoSomeAsyncStuff(string text)

    //{

        //Console.WriteLine("test " + text + " " + Thread.CurrentThread.ManagedThreadId.ToString());

    //}



    //private static async void DoSomeAsyncStuffV2(string text)

    //{

        //await Task.Run(() => Console.WriteLine("test " + text + " " + Thread.CurrentThread.ManagedThreadId.ToString()));

    //}

}

What's the difference?

The async keyword will instruct the compiler to build a state machine with being the code between the beginning of the method' execution flow and the first await, the code between any two consecutive awaits and between the last await and the return of the method.

The return type of the method is either void if you don't care about the result or if the method completes (beware of this), Task if you want to await the execution of the method but don't want to return any value or Task<T> if you want to await the execution of the method and return a value of type T.

If the method doesn't have the async modifier, than it's just a "normal" method.
