Hello,

I have a fundamental question that I seem to have difficulty grasping.

I want to build a n-tier vb.net app, (not a web app), in a network environment.

Could I build the server side code as a collection of assemblies in a server share that I can reference in the Client code under project references ?

and if so, could I simply instanciate the classes within those assemblies from the client code ?.

Would I need marshaling or proxies ?.

Thanks,

Tino M.
 
I use one Assembly for each level in an n-tier application:

- User Interface
- Business
- Data Access Layer

Each Assembly is comprised of multiple classes that represent objects, and the class is then intantiated by the layer above it.


Hope this helps a bit

Thanks for your reply Roey,

I think that your comments validate my idea that in a network environment, a client machine can instantiate and use the methods and properties of the classes inside the (server machine) Business logic assembly / ies.

What would you suggest I use if I now want to let remote
(out of network) users utilize the same server assemblies?.

sockets?

.net Remoting?

Thanks,
 
Sorry but havent done that before, and wouldnt want to guess and lead you in the wrong direction.

Thanks everyone for your comments on my questions.

I am familliar with webservices, but I dont want IIS involved in this application (If I understand it correctly webservices live in an IIS VD).

I am looking into remoting, or COM+ .....


Thanks again!

Tino Mesa.
 
Id go remoting in preference to COM+ unless you need features specific to COM+ as it is heavily based on Microsoft standards and RPCs (all data is a binary format as well).

With ermoting you can still use XML (SOAP) and http so to all intents and purposes it is a webservice but without needing IIS (more work than a webservice but maybe worth it.)
