>I just found it right before you responded, but didn't get back to my posting in time to add the info I had found. It seems that it comes up in IntelliSense when you type part of it, but it should also show in the PEM box, buit it isn't there. I wonder if the first service pack for ASP.NET 4.0 will make sure it shows up?

Can you post the thread reference, please?

You may want to file a bug report on Connect website if this is not there yet.
