Alternative to Dispatcher class for .NET 2.0

Question

I'm new to threading. While learning from WPF sample (A Wix Bootstrapper application), I've came across the use of System.Windows.Threading.Dispatcher in Run() method something like:

MyDispatcher = Dispatcher.CurrentDispatcher;
.
.
//rest of the code 
.

Dispatcher.Run(); //This I believe invoke the app in a thread (plz correct me if I'm wrong).

Requirement: I'm trying to implement same in a Windows form application (Have to be for Net FW 2.0 for some reason), where I only have System.Threading namespace.

*Question:*How can I implement similar functionality like Dispatcher using System.Threading namespace?

i'm not following question, are you asking how do you invoke an operation on a new thread? — T McKeown, Jan 13 '14 at 15:05
FYI, you're likely to have more problems than just `Dispatcher.Run`, coming from .NET 3.5 back to .NET 2.0. — John Saunders, Jan 13 '14 at 15:08

Use the Control.Invoke method and the Control.InvokeRequired property instead.

Here's the sample code for .NET 2.0

// Called from any method
new Thread(() => { UpdateRequest(); }).Start();

// Background activity
private void UpdateRequest() {
  UpdateUI("new text everytime" + DateTime.Now.ToString());

}

private void UpdateUI(string request)
{

  if (control.InvokeRequired)
  {
    this.Invoke(new Delegate(UpdateUI), new object[] { request });
  }
 }

Update: Had accidentally used TPL as haven't used .NET 2.0 since long, replaced with native Threading
