(This isn't really a question )
I THINK this has to do with intellisense. A while ago I noticed that some of the stuff that showed up in intellisense under C# didn't show up in VB.NET's intellisense (few rare ocasions, I don't even remember what the methods were)...
I was looking through the IDE options and I saw this option, so I'm assuming that this was the reason:
-in the "text editor" tab, then in "basic", "hide advanced members" is checked by default while this isnt checked in C#....
If this is for something else please let me know, but I think it's for the same intellisense stuff that I'm talking about
