return DataSet in WCF?

Question

Hi everyone,
WCF noob here...
We have VB.NET 2003 web services that are returning datasets...
I need to write a REST WCF service and return those datasets.
I cannot use LINQ since the database is SQL 2000 ...

so is it possible to return a whole dataset in wcf?  I haven't found
anything on returning datasets yet...

Are there any examples on the web?
TIA
