What you need is xml comments - basically, they follow this syntax (as vaguely described by Solmead):

C#

///

///This is a description of my function.
///
string myFunction() {
     return "blah";
}

VB

'''

'''This is a description of my function.
'''
Function myFunction() As String
    Return "blah"
End Function
