Sure have a look here: http://www.pastie.org/617135
then you can use it like:
Dim ctx As New DataContext()
Dim stockitem As Stock.Stmaster
stockitem = ctx.RandomOne(Of Stock.Stmaster)()
stockitem = ctx.Load(Of Stock.Stmaster)(17)
and saving like this:
_ctx.BeginSave()
_ctx.Save(_jobcard)
For Each d As Jobdetails In _jobcard.Details
_ctx.Save(d)
Next
_ctx.EndSave()
there is also criteria and query support,etc. The main idea is to have
all database access go through the datacontext class. We normally have
one context per form.
You probably won't be able to use it out of the box but might give you
a few ideas :-)
Hope this helps.
