I'd like to add my answer to complement the answer which has already been accepted. Depending on what you're trying to do, often it's possible to avoid the added complexity of async delegates and wrapped tasks. For example, your code could be re-factored like this:

class Program
{
    static async Task Test1()
    {
        System.Console.WriteLine("Enter Test");
        await Task.Delay(100);
        System.Console.WriteLine("Leave Test");
    }

    static async Task Test2()
    {
        System.Console.WriteLine("Enter callback");
        await Task.Delay(1000);
        System.Console.WriteLine("Leave callback");
    }

    static async Task Test()
    {
        await Test1(); // could do .ConfigureAwait(false) if continuation context doesn't matter
        await Test2();
    }

    static void Main(string[] args)
    {
        Test().Wait();
        Console.WriteLine("Done with test");
    }
}
