Intellisense doesn't work for Attributes

Hello,

I was wondering if this is happening for anyone else. It seems that when I try to add an attribute to a property on a class, LINQPad doesn't have intellisense information for the constructor of the attributes.

This happens even if I hit Ctrl+. to have the auto-complete window appear. The window will show up but doesn't show the constructor to the attribute.

public class Test
{
	[JsonProperty("name")]
	public String Name { get; set; }
}
