Introduction:
Assume having a MyApp.MyClass class bearing both data (say, DataSets)
and functionality (proprietary methods).
A WebService exposes this class via some GetMyClass WebMethod.
A WSDL-generated proxy class (localhost.MyCl ass) on the client side,
naturally, has only the data of the original class "mirrored" (well,
that's reasonable, since the WebServices are there to provide data
objects...).
Now, to the question.
What is the proper pattern to be applied in order for the client to be
able, after receiving a (proxy-side type, localhost.MyCla ss) object
from GetMyClass WebMethod, to be able to invoke the methods of the
original MyApp.MyClass on that object's data?
Is it something to do with namespaces?
Should I build a library to be put on the client side (in the GAC?)
and referenced from the client object?
Should I create & override (extend) the proxy class by myself, and
provide the client with it (instead of client's generating the proxy
by itself)?

yes, as you point out, the philosophy of webservices is to exchange
MESSAGES, not objects.
Therefore I advise you to use the DTO pattern. http://msdn.microsoft.com/library/en...tml/DesDTO.asp
If you want to violate the philosophy of sending messages, and actually send
objects across the wire, then , yes you can do that too.
follow these steps:
define your service class to return MyClass
Build your shared MyClass into a distinct (shared) assembly
install that assembly on both client and server
generate the webservice proxy in the normal way
modify the webservice proxy - remove the generated (neutered) type and
replace it with the SharedAssembly. MyClass
off you go.

Hello everyone, I have been researching the Singleton Pattern. Since the
singleton pattern uses a private constructor which in turn reduces
extendability, if you make the Singleton Polymorphic what sort of

Also, I see that a singleton needs to be set up with certain data such as
file name, database URL etc. What issues are involved in this, and how
would you do this?

Hello All,
I am designing a class based on singleton pattern. Inside this class I have
multiple instance methods. My question is since there will be only one
instance of this class at any instance of time in the whole application there
is no use in having these methods as instance methods I can as well have
static methods....correct?
If I leave these methods as instance methods would they have any wrong
impact on my application?

Hi All,
I have a web service derived from MarshalByRefObject (i.e. Not
WebService) that also implements the IDisposable interface. The problem I
have is with the implementation of the public Dispose method required by
IDisposable. When WSDL.exe (or 'Add Web Reference') extracts the interface
information for the web service it also publishes the Dispose method.
Can anyone tell me how to prevent the Dispose method from being published by...

Is there a way to get VS2005 to generate the Begin/End pattern (as VS2003
always did) for async web service calls rather than the
MethodAsync/MethodCompleted pattern when adding web references?
The MSDN documentation seems schizophrenic and references both patterns, but
I can't find a way to change the behavior back to the VS2003/Begin/End style.
The Begin/End pattern is just much more convenient for some scenarios.
Thanks!

I want to expose the whole functionality of a library through a web service. In order to do that of course I've created web methods for all public methods in this library. Because only public data and no logic or private fields is transferred through web services, I need to know what is the correct pattern for invoking the methods of the proper objects.
By now I've found two possible patterns:
