I have some question about the subject:
I want to implement the S.L. pattern and:
1)I must implement a singleton instance?
2)Is a good idea to use the wsdl document(or it is necessarily) so I
must use the dinamic proxy invocation?
3)Is possible caching the references?
I found in the web some informatione but many approximating so if you
have some infomation and links....
Thanks all...
