Handling exceptions from the synchronous part of async method

Question

I\'m dealing with the situation where the task I start may throw, while still executing synchronously on the initial thread. Something like this, for illustrative purposes:

Answer 1

I'd split it into two parts, rather than relying on task.GetAwaiter().GetResult() to work. I'd be afraid that someone maintaining TestAsync could unwittingly break things in the future.

This is how I would write it. This should preserve the behavior you've got, but I find it more obvious what's going on:

static Task Test()
{
    var random = new Random(Environment.TickCount).Next();
    if (random % 2 != 0)
        throw new ApplicationException("1st");

    return TestAsync();
}

static async Task TestAsync()
{
    await Task.Delay(2000);
    Console.WriteLine("after await Task.Delay");
    throw new ApplicationException("2nd");
}



static void Main(string[] args)
{
    try
    {
        Test();
        Console.WriteLine("TestAsync continues asynchronously...");
    }
    catch (Exception e)
    {
        Console.WriteLine("Error: " + e.ToString());
    }

    Console.WriteLine("Press Enter to exit...");
    Console.ReadLine();
}
