Hi,

I've just started with eth MM .NET Jump Starts and have reached Step 7 in Creating Business Objects and when I try to invoke the Order1.GetOrderByOrderID() method, I enter the Order Id I want then I get this error:

An unhandled exception of type 'System.InvalidOperationException' occurred in System.Data.dll

Additional information: The ConnectionString property has not been initialized.

I'm not sure where to go from here. the connection string worked previously while using the Business Layer Generator.

Any advise on what to look for?
