I've written a number of n-tier products in vb6 using the Duwamish Books example method as mentioned by microsoft. However, there are no such examples for .net.
My problem is i'm trying to build an equipment hire application. I want to creat as one of my objects and equipment object that will sit in my middle layer. It will talk to sequel through ado.net. The 1st layer ie the GUI will simply validate and display date that will come from the Equipment object the 1st tier will instantiate. However, all examples show the display layer being bound directly to the the database through ado.net..you know the datagrid having an ado.net data set as a source. I want to see an example that uses the middle business layer to bind to the forms controls...I cannot find one..has Microsoft abandoned n-tier architecture ?

Some one who knows please tell me
