All processes have at least one thread of executions, which is called?

When a program in C# starts execution, the main thread is automatically created. The threads created using the Thread class are called the child threads of the main thread. You can access a thread using the CurrentThread property of the Thread class.

The following program demonstrates main thread execution:

using System;
using System.Threading;

namespace MultithreadingApplication
{
class MainThreadProgram
{
static void Main(string[] args)
{
Thread th = Thread.CurrentThread;
th.Name = "MainThread";
Console.WriteLine("This is {0}", th.Name);
Console.ReadKey();
}
}
}
When the above code is compiled and executed, it produces the following result:

Output: This is MainThread
