How to tell if a thread is the main thread in C#

Question

I know there are other posts that say you can create a control and then check the InvokeRequired property to see if the current thread is the main thread or not

Answer 1

static class Program
{
  [ThreadStatic]
  public static readonly bool IsMainThread = true;

//...
}

And you can use it from any thread:

if(Program.IsMainThread) ...
