In a few webmethods I built, I had them return a datatable object... BUT I got the error:
Cannot serialize member System.ComponentModel.MarshalByValueComponent.Site of type System.ComponentModel.ISite because it is an interface
So I changed to dataset and it worked like a charm...
why? The datatable is Serializable so there should be no problem creating a proxy class...
kind regards

I am pretty sure I read somewhere that tables cannot be returned although I am hoping they are wrong.
I see no reason why?
Perhaps Im old fashioned, but I always work with the principle, if I don't need disconnected data with many relations, I always use the datatable OR datareader... no point in using a heavy dataset object if you don't use it's functionality....

No point in using a heavy dataset unless you have to in order to return a datatable as is the case here. I believe the issue has to do not with just being serializable but it has to support XmlSerialization for webservices which a datatable does not(but i think they have made the datatable a little more separated from the dataset in the next release of .net)
