Uses Synchronization Contexts in the Windows form

There is a way to allow windows form of Synchronization Contexts. Use code like this:

using System;
using System.Threading;
using System.Runtime.Remoting.Contexts;
[Synchronization]
public class AutoLock : ContextBoundObject
{
public void Demo()
{
Console.Write ("Start...");
Thread.Sleep (1000); // We can't be preempted here
Console.WriteLine ("end"); // thanks to automatic locking!
}
}
public class Test
{
public static void Main()
{
AutoLock safeInstance = new AutoLock();
new Thread (safeInstance.Demo).Start(); // Call the Demo
new Thread (safeInstance.Demo).Start(); // method 3 times
safeInstance.Demo(); // concurrently.
}
}

According to this point:
Automatic synchronization cannot be used to protect static type members, nor classes not derived from ContextBoundObject (for instance, a Windows Form).
