Hi Mortals,

I built the Windows Forms - C# Jump Start application and ran it successfully using the following database key in my app.config file:
<databases>
   <add key="Northwind\Connection" value="server=(local);Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=Northwind" />
</databases>
I then moved onto building the Web Forms - C# Jump Start application and used the following database key in my web.config file:
<databases>
    <add key="Northwind\Connection" value="server=(local);Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=Northwind" />
    <add key="Northwind\DataAccessClass" value="DataAccessSql" />
</databases>
During design time, the wizards are able to connect to the data tables and display the appropriate fields for BindingSourceMember selections. However, at runtime, I receive the following error when a bizobj method attempts to access data.
