Is IntelliSense showing you everything?

Well I learned something new today. I can't believe I have been developing in Visual Studio .Net for so long without knowing this one. I'm sure someone showed me at one time or another. If they did I forgot.

A colleague of mine mentioned I should use a particular property on a particular class. When I went to use it, it did not show up in IntelliSense. I mentioned this to my very clever friend, who pointed out the following option to me. Apparently the property I was trying to access via IntelliSense was flagged by the developer as an advanced member.

If you have members in a class that you want to be treated as advanced, use the following attribute;

EditorBrowsable(EditorBrowsableState.Advanced)
