.NET 2.0 datalayer/business layer

[Guest]

I'm looking to create a project that just has our business layers and
datalayers in it so more then one project can use it. My question is I want
to use TypeDatasets, is the creationd of typedDataSets the same as it was in
03 and were can I find some information on datasets in 05?

They're creation is virtually unchanged as far as I can tell. They're
functionality is also just as good with added speed benefits (they're
indexed now and inserting items and searching is a lot faster.... and they
serialize (across physicial n-tiers via Remoting) as true binary rather than
some xml/binary hybrid).

They also now sport a tighly-coupled Data Access feature that harkens back
to VB.Classic ADO RecordSet days. in the form of the TableAdapter which
offers a more robust wrapper around DataAdapters. However, I highly
recommend against using TableAdapters. While it seems to encourage "logical"
tier principals, it actually violates n-tier principals. You can't place the
TableAdapters in a separate Dll. The consumer of the Dataset have access to
the TableAdapters. The TableAdapters have to exist on both the server and
client.... so on and so forth. They're nice but ILL-CONCEIVED.

See here for a nice synopsis.
