Hi,
I am trying to return a dataset from the webservice, but it shows an error arrayofXElement not found.
What could be the reason?Is it possible to return a dataset from a webservice?
If not, could you tel me the work around for this?
Thank you.

you can't use datasets in silverlight. or datatables, or datarows...
you need to return a list of custom business objects.

its no different than a normal webmethod. instead of returning a dataset, you'd return a list of YourObject.
this video is extremely helpful:

You can use Linq to Xml Classes and can return List of Objects instead of returning dataset..

i would suggest to use Enitity Model instead of datasets to work with Silverlight application which connects to the database.
Entity Model is easy to create and query using Linq to object.
you can create WCF service for silverlight and in those service return the Entities not the datasets.
dataset , datatable are not available in sivlerlight

i Had a similar thing when I was new to SL.
The mistake i was doing was that SL application was set as the startup project
I guess you try and set the website as startup project
