Within the TwainSession class in the .NET 14.5 classes there are a whole pile of properties that can control how the transfer takes place and how the scanner works.

If I set EnableAutoFeed to true in between a Get/Set properties call it doesn't appear to use the sheet feeder when scanning, whereas if I set the capability manually using TwainCapabilityType.FeederEnabled it will use/not use the sheet feed or flatbed correctly.

Is there some documentation available that details what each of the properties within the TwainSession class actually set, and any relationships betwen them.

Those two are different capabilities.  The FeederEnabled
capability needs to be set first to enable the feeder.  It does
not cause the application to actually scan from the feeder.  Setting the EnableAutoFeed capability afterwards does this job.
