.net 4.5 async syntax

Question

I wrote the code below,

Task.Factory.StartNew<int>(async () =>
        {
            await Task.Delay(1000);
            return 42;
        });

but the read line appeared under the "async" keyword, and the code cannot compiled due to some syntax error, can anybody advise me what to do?

Thx a lot!

Answer 1

You probably want to use Task.Run, which has more natural syntax for async lambdas:

var task = Task.Run(async () =>
{
  await Task.Delay(1000);
  return 42;
});
