I'm trying to build a chart in my application which will act as a client for an ASP.NET 3.5 web service that I created. The error I get is as follows:
Series data points do not support values of type System.Data.DataViewManagerListItemTypeDescriptor only values of these types can be used: Double, Decimal, Single, int, long, uint, ulong, String, DateTime, short, ushort.

'get a dataset with the response from the service
Dim ds As DataSet = New DataSet()
ds = serv.ViewSalesStats()

I added refernece MySql.Data to my project. My web.config looks like that:

But when in ServerExplorer I try "Add Connection..." I can't find "MySql Database" in the "Choose Data Source" dialog box?
What the problem can be?
