Start task work with named methods so each worker body remains traceable.

Task Method Group

TaskMethodGroup.cs
using System;
using System.Threading.Tasks;

class Program
{
    static int baseValue;

    static int CalculateLeft()
    {
        int result = baseValue + 3;
        return result;
    }

    static int CalculateRight()
    {
        int result = baseValue * 2;
        return result;
    }

    static void Main()
    {
        int seed = ;
        baseValue = seed;

        Task<int> left = Task.Run(CalculateLeft);
        Task<int> right = Task.Run(CalculateRight);

        int total = left.Result + right.Result;
        Console.WriteLine($"seed={seed}");
        Console.WriteLine($"total={total}");
    }

task `Task.Run` can receive a method group, keeping the concurrent worker logic in ordinary named methods.
