Which spelling is appropriate based on .<A href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpgenref/html/cpconnetframeworkdesignguidelines.asp">NET Design Guideline</A>?</FONT></FONT></P> <P>The answer is <STRONG>Callback </STRONG>as &#8220;callback&#8221; is a single word. Going forward we should not see the spelling of <STRONG><EM>CallBack </EM></STRONG>in new Fx APIs. </P><img src="http://blogs.msdn.com/aggbug.aspx?PostID=85210" width="1" height="1">Design
