Hello,

I have a Windows form application that currently uses a database local to
the machine it is running on. We are planning on setting this application
up for a multi-user environment, so I would like to change to a 3-tier
architecture application for scalability:

1. My Client
|
2. My Business Logic Server (The client connects here)
|
3. My database server

We may also create another web form client in the future, and I would also
like that to connect to the business logic server as well.

My question is, what type of communication do you guys recommend between the
exist client and the business logic server?

1. If I use .NET remoting, can an ASP .NET page easily utilize the .NET
remoting code if I create an additional web form in the future?

2. If I setup the logic server to provide web services to clients, I have
heard that web services don't support transactions across multiple database
servers, so if I can't use web services, what should I use?

Any help is greatly appreciated. Thanks.

You may have to think in a different way.

Yes, you can do that.

Oh, yes you can if you know what you're doing. CSLA does just that if you
want it too. You may not even use CSLA Framework ever on a project. But you
can download it, put the CSLA Framework together. It has the source code of
the CSLA Framework, the Windows Desktop and Web forms Tracker project
source code that uses the CSLA Framework using the same objects derived from
the CSLA Framework in both environments, using a Web service, .Net
Remoting and transactional mode across databases.

Like I said, you may never use the CSLA Framework on a project, but you can
look at the code, understand the concepts and you might be able to come-up
with your own (roll your own) and run with it.
