Should we call Wait method when we call Result property in Tasks? C# Parallel Programming

[ShervanN]

Hi,

In chapter 17 Parallel Programming, Page 541, You wrote:

    public static void TaskWithResultDemo()
    {
        Task<(int Result, int Remainder)> t1 = new(TaskWithResult, (8, 3));
        t1.Start();
        Console.WriteLine(t1.Result);
        t1.Wait();
        Console.WriteLine($"result from task: {t1.Result.Result} {t1.Result.Remainder}");
    }

Should we call the Wait method when we call the Result property? In my opinion, we don't need it.
According to Microsoft learn:

Accessing the property's get accessor blocks the calling thread until the asynchronous operation is complete; it is equivalent to calling the Wait method.

It's page 451 in the book. The text in the book also mentions that the Result property of the Task<T> type blocks the calling thread, so a Wait is not required. With the first WriteLine after starting the task, there's also not a Wait, and the result is shown.

What's better than using the Result property is to use the await keyword. This doesn't block the calling thread.
