WCF not returning data in DataTable, even though that's what I told it to do

[Ronald S. Cook]

Thanks for reading this.

I've successfully implemented a WCF solution. However, even though I
designate the return type to be DataTable in my class on the server (hosted
under IIS), it comes back as the following in the generated proxy class:

Public Function SelectCountryByID(ByVal guiID As String) As
SelectCountryByIDResponseSelectCountryByIDResult

Now, it doesn't do this when the type is a simple String, but this long
weird thing is what I get for DataTable.

Thanks for any thoughts,
Ron

What does your operation contract definition look like?
In C#:
[OperationContract]
DataTable GetMembers( )
{
// body here that returns a DataTable
}

Weird.. if I make the type DataSet it returns as such, but not DataTable. I
wonder why it doesn't like DataTables.

Is your datatable a .NET 2.0 version? Only the 2.0 version is serializable, earlier versions are not. The dataset has been serializable all along.
