webservice advice

[Gary Howlett]

Hi

Im using VS 2005 C#;

Is there any issues I should be aware of if I add my webservice as a static
variable to my main class?

The reason im asking is should I create an object of my webservice everytime
I wish to invoke its methods, or just use a static instance of the
webservice created when the application loads. My webservice is a "Data
Tier" to the application. In addition I use SoapHeaderAttributes so it saves
me adding these everytime I wish to make a call. But my concern is about
calling the methods asynchronously? any threading issues etc to be aware of?

Any info be much help.

Thanks

Gary

The only issue you might get sharing the same instance among threads is if
processing more than one thread your call will queue as there is a maximum
of 2 connections by default under Windows.

Having said this, I never do what you are doing. I tend to make my code less
coupled. The client is completely unaware of the Web Service and the
business logic creates an instance of the proxy per call. The overhead here
is not that great and simplifies the code.

Simon.
