Question

I have some Service class which is defined as InstanceContextMode.Single, and is well known in the hosting application. (The host creates an instance, and passes that to the WebServiceHost)

Hosting app:

WebServiceHost host = null;
SomeService serviceInstance = new SomeService("text", "more text");
host = new WebServiceHost(serviceInstance, baseUri);

Problem:
When I go to use the variables initialised when the service is created (ie, when a call is made to the service), they are either null or empty…

Am I wrong in assuming that as the instance being initialised in the hosting application is used for each request to the WebServiceHost?

Any pointers here would be great.

Answer 1

Your assumption seems correct to me.
Did you put the right code in the service constructor?
