Hi, all! I have several questions about WCF reliable session reliability: Does WCF re-serialize a message during a retry attempt? 2. If 1 is correct - does it happen after message parameters were disposed or not? 3. If 2 is correct - is there any way to identify message was sent for sure? I could not yet figure that out via reflect...

I've enabled query cache for one of my queries, it works fine (query result is taken from query cache and entities from second level cache) when I run a test or a console application. However, if I run the same queries through a WCF service, the cache is never hit. I've also checked the logs in both cases and they are practically ident...
I have an application that uses WCF for all DataAccess. It returns some business objects and it has some operations. Should this code exist in my Client or in my Service? If in the service, HOW should I implement it? Can I simply add it as an interface to my business object? Will that come through the WCF Service Proxy Code? (This is a...
We have an application which invokes a third party web service and there is a significant amount of work to generate the request (it's a fairly large object tree and there are 30-40 unique contract schema generated classes to potentially instantiate) based upon the class structure used on our side of the invocation. I had a thought of de...

Please provide some real ...

I'm using WCF through Spring.net WCF integration link text This works relatively fine, however it seems that WCF and Spring get in each other's way when instantiating client channels. This means that only a single client channel is created for a service and therefore the clients get a timeout after the configured timeout is expired sinc...
Hi there, We have a website hosted with heart internet and are seeing some strange behaviour and have no idea what could be causing it at this stage.

Hi, I am trying to get a further understanding of message buses and one question that keeps coming up in my head is "how does the message get onto the bus?". Now, I assume there is a service (WCF, etc) of some sort that receives messages and puts them onto the bus. So then the other question I have is isn't this service then likely to b...
I have a need to do some real-time rpoerting on the functionality of a WCF service. The service is self-hosted in a windows app, and my requirement is to report "live" to the host app when certain methods are called by the client. My initial thought on the task was to publish a "NotifyNow" event in the service code, and subscribe to th...
