gistfile1.cs

class Program
{
    static void Main(string[] args)
    {
        Console.Out.WriteLine("Baking cookies");
        BakeCookies();
        Console.Out.WriteLine("Cookies baked");
        Console.ReadLine();
    }

    private static async void BakeCookies()
    {
        await TaskEx.Run(() =>
        {
            Thread.Sleep(1000);
            Console.Out.WriteLine("Done baking");
        });
    }
}

Output:

Baking cookies
Cookies baked
Done baking

But Visual Studio will draw squiggly lines below non-async calls to async methods, right?

That's entirely possible, but I haven't seen any comments on it in the specs or whitepapers.

That said, I'd much rather have clear naming, than yet more warning and information markers within VS :)
