Previous Post: ---------------------------------- C##: First, I created 4 new blank projects in Visual Studio 2010 for the sample apps (BaseXClient.cs, CreateExample.cs, Example.cs, QueryExample.cs). After I added the references "System" and "Microsoft.CSharp" most of the errors went away, but there are 2 remaining: (1) The types "Session" and "Query" are not recognized. I am sure they are somehow part of BaseX. How do I add support for those types? It probably involves creating some reference and adding it, correct? (2) The other type that is not recognized is "Stopwatch". Microsoft provides one such class: http://msdn.microsoft.com/en-us/library/ebf7z0sw.aspx which has a "Start" method and a "ElapsedMilliseconds" property. ---------------------------------- Please ignore the question above that refers to "Stopwatch". I solved that. The question that remains is about adding a reference to support "Session" and "Query". It sounds like all I need is a DLL. TIA, -Ramon
