Question: I copied below code from [this](http://blogs.msdn.com/b/csharpfaq/archive/2012/06/26/understanding-a-simple-async-program.aspx) link.But when I am compiling this code I am getting an **entry point cannot be marked with the 'async' modifier**. How can I make this code compilable?

```
class Program
{
    static async void Main(string[] args)
    {
        Task<string> getWebPageTask = GetWebPageAsync("http://msdn.microsoft.com");

        Debug.WriteLine("In startButton_Click before await");
        string webText = await getWebPageTask;
        Debug.WriteLine("Characters received: " + webText.Length.ToString()); 
    }

    private static async Task<string> GetWebPageAsync(string url)
    {
        // Start an async task. 
        Task<string> getStringTask = (new HttpClient()).GetStringAsync(url);

        // Await the task. This is what happens: 
        // 1. Execution immediately returns to the calling method, returning a 
        //    different task from the task created in the previous statement. 
        //    Execution in this method is suspended. 
        // 2. When the task created in the previous statement completes, the 
        //    result from the GetStringAsync method is produced by the Await 
        //    statement, and execution continues within this method. 
        Debug.WriteLine("In GetWebPageAsync before await");
        string webText = await getStringTask;
        Debug.WriteLine("In GetWebPageAsync after await");

        return webText;
    }

    // Output: 
    //   In GetWebPageAsync before await 
    //   In startButton_Click before await 
    //   In GetWebPageAsync after await 
    //   Characters received: 44306
}

```

Answer: 
I'm using C# 8 and its working fine.
------------------------------------

```
static async Task Main(string[] args)
{
   var response = await SomeAsyncFunc();
   Console.WriteLine("Async response", response);
}

```

**OR without "await" keyword.**

```
static void Main(string[] args)
{
   var response = SomeAsyncFunc().GetAwaiter().GetResult();
   Console.WriteLine("Async response", response);
}

```
The difference between the code in the link's example and yours, is that you're trying to mark the `Main()` method with an `async` modifier - this is not allowed, and the error says that exactly - the `Main()` method is the "entry point" to the application (it's the method that is executed when your application starts), and it's not allowed to be `async`.
