ThreadPool Extensions

A better more versatile way to do this is to use Task<> objects

public static class ThreadpoolExtensions
{
    // Execute a method/procedure on the thread pool
    // The state parameters allow you to pass parameters into the thread routine 
    public static bool ExecuteOnThreadPoolThread<T>(this Action<T> threadRoutine, T args)
    {
        return ThreadPool.QueueUserWorkItem(s => threadRoutine((T)s), args);
    }

    // Execute a method/procedure on the thread pool
    public static bool ExecuteOnThreadPoolThread(this Action threadRoutine)
    {
        return ThreadPool.QueueUserWorkItem((obj) => threadRoutine());
    }
}
