More than 1 web service?

I have several tasks that my web applications need to do. They are managing
membership, News, Events, Legal forms for admin, Legal forms for customers,
audio and maybe a few other things here and there. A lot of these things
will be used in more than 1 web application. I am trying to centeralize
everything into as much reusable code as possible. What I need to know is:
Do I take these different tasks and break them down into different web
services? Or use different classes in the web service for each task? How
exactly does hhis work? Can WCF web services use datasets and other kinds of
data manipulation/storage related objects? and can you use the default
asp.net or your own defined membership provider in a web.config file to
manage membership in a web service?

I am new to WCF web services and don't really know anything about them
except that they are a place where you can centeralize all of your code for
use in more than 1 application. Where would I start out with this? I was
told I should use WCF web services over the other types. Why is this?

You should consider this by "why I want to split them" ?! for the sake of
what?!

yep

The same web server with different web applications. There is a little
possibility that a client windows application will be built to be used from
a remote computer.
who is using them,
Click to expand...
The website admin For the administration of legal forms for admin, News,
events, audio and partially the legal forms for customers. The customers
will use it for the legal forms for customers. The rest of it like
membership/profile providers would be used by the internal web application
system to provide access to these different parts.
do they have the same rights
Click to expand...
Can you explain what you mean more by having the same rights? If you mean
having the same access rights to the different sections of the web
applications and if they have control over the data stores being used, I
would imagine that each WCF service in the WCF service project would be
restricted to its own data store and the access to things would be limmited
to what they individually would need in order to get their jobs done. For an
example, the Audio service would not need to know what is going on with the
services for legal forms. Using the Audio service example, It would need
access to a database with membership provider, its own database to store
audio related information and it would need to have access to the app_data
folder of the project that makes use of the audio service. This means that
the Audio service most likely would need access to the Membership service to
determine if the admin was loged in or not. This is nowhere an extensive
layout, but is a good example of one of the service requirements. Actually,
most of the services I would need would probably need access to multiple
locations on the solution like the audio example.

You should consider this by "why I want to split them" ?!

Just trying to be more organized with the code. Why would you want methods
for an Audio service located in a membership service? Well, ok not the best
example, will try this again. Why would you want to mix methods for the
Audio service with the methods from the News or events services? They are
totally unrelated for one, and it makes it easier for me to know what
service/section of the service to jump to if they are divided into multiple
services.
for the sake of what?!

What do you mean by this? See abovwe. Unless there are too many
risks/performance problems with dividing the services up into each task
type...Let me know if there are any?

I had a huntch you could but figured I would ask first.

exactly. split them logically and extract common stuff to the separate assembly

if you are not going to end up with the 100 webservices I wouldn't consider

So, the basic conclusion is that it would be best probably to create a WCF
service project and create different services in that project for each task
that the web applications need to complete... Just making sure I get the
final line before starting...
