Let's say I have a strongly-typed dataset that contains multiple tables.  And, let's call this dataset 'Orders'.  How can I create an object with Strata-frame?  All of the documentation points to one table per object.  Not that the attachment is a 'real-life' example.  But, I don't want to upload what I use at our company for public consumption.

Thanks a lot for this Robert. I'll file it away for when my SF level rises

The underscore is just a convention that we use internally.  It's not a .NET naming convention.  However, with VB, when you create a "Public WithEvents MyField As SomeType" field on your class, VS behind the scenes creates a field named the same as your field, but with an underscore (_MyField) and instead of creating a public field, it wraps the implicit private (_MyField) with a public property. 

Other than that, I don't know of any convention that says that your private fields (or any other member fields) need to start with an _.  We just do because we like the convention.  I've looked through the .NET framework using Reflector a few times, and in most of their stuff, they either start their private fields with an _ and camel case them or just camel case them (_myField or myField).  It's entirely up to you.

I can't find the MSDN page that lists the .NET naming conventions, but this guy has most of them listed.  Look down at the one that says "Class-Level Private and Protected Variables"
