Updating UI from non-UI thread

In .NET 2.0:

void vj_engine_VowelGenerated(PatternDataCLR patternData)
{
    if (this.InvokeRequired)
    {
        this.BeginInvoke(new VJEngineCLR_vowelGenerated(vj_engine_VowelGenerated), new object[] { patternData });
        return;
    }
}

In .NET 3.0:

using System.ComponentModel;
...
namespace MyNamespace
{
    ...
    public class MyClass
    {
        AsyncOperation operation;
        ...

        public MyClass()
        {
            operation = AsyncOperationManager.CreateOperation(null);
            ...
        }
        
        void nonUIThreadEvent(...)
        {
            operation.Post(new System.Threading.SendOrPostCallback(delegate(object state)
            {
                // do something 
            }), null);
        }
    }
}
