Using the ValueTask of T object in C# 7.0

By now probably all .NET developers are aware of the await and async keywords, what they do and how they work.

Here’s a small example where the CalculateSum function simulates a potentially time-consuming mathematical operation:

public class AsyncValueTaskDemo
{
	public void RunDemo()
	{
		int res = CalculateSum(0, 0).Result;
		Console.WriteLine(res);
	}

	private async Task<int> CalculateSum(int a, int b)
	{
		if (a == 0 && b == 0)
		{
			return 0;
		}

		return await Task.Run(() => a + b);
	}
}
