Hello Benson,

B> Question:
B> 1. Can we say .NET 2.0 framework is an application server layer?

Nope. framework is the framework. it's the platworm to build your apps.

B> 2. Sometimes, we create an application server program which sits on
B> the server side and talks with the database server. Doing this, all the
B> client programs talks with this application server, so increase the
B> scalablity. Is it scalable in using Web Services or .NET remoting for
this purpose?

What are u describing is the DAL - data access layer.
The better way is to use WCF, if net - than to WS or Enterprise Services
(COM+)
.NET is not very good from the declarativeness perspective.

B> 3. Any application server framework can be recommended in .NET 2.0?

BizTalk :) But it's very huge and I don't think it's exactly what u need.
Everything you need to build is the small set of services which provide the
necessary functionality on server. For these reasons windows COM+ - the set
of services.
I suppose it's the right way for your, depending on your functionality
