async/await (C# 5)

async/await simplifies asynchronous code using Tasks.

public async Task<string> GetDataAsync(HttpClient http)
{
    var res = await http.GetStringAsync("/api/data");
    return res;
}

Notes

• Avoid async void (except event handlers).
• Propagate cancellation with CancellationToken.
