The following code ( an example taken from a book ) defines duplex contract for a service that provides stock price updates. It uses duplex communication so that client can register for updates, and the service will periodically send updates to the client: using System; using System.Collections.Generic; using System.Linq; using System.T...
Anyone have suggestions how to architect the following setup: ASPX, IIS, 100s of transactions coming through the web pages and data which changes once a day & has to be processed at start-up (would be slow to reload & calculate from the database 100 times a day) Currently we have: ASPX pages running on IIS, communicating with A window...
Hi guys, I'm trying to build out a WCF service but I've run into a blocking issue. I've been Googling around but I haven't been able to make any progress. Hopefully I'll have more luck here. Let's say I have a job class defined as such: [DataContract] public class Job : IJob { public Job(...) { } [DataMember] pu...

I'm currently building a .net web application that uses WCF web services to allow a Flex front end to access the database. I'm in the process of setting up some unit/integration style testing on the web services and am trying to work out the best way to allow the tests to access and modify data in a separate test database. Currently, t...

I have a asp.net webservice that calls a WCF service. On my development machine this is working fine. But if i deploy my ASP.net Webservice it is not working. Both the ASP Webservice en W...

Hi everyone, I currently code an internet cafe software in WCF for 25 clients. I read much about instanceContextMode, Concurrency and Duplex and other stuff and saw that everyone was having problems because of wrong implementation of these settings.

I have a SqlMembershipProvider store with Roles enabled. This is configured and has the user "devtest" in the roles "xxUser" and "xxAdmin".

Since ws-discovery is not working for me, I'm searching for alternative solutions with similar functionality. I prefer it simple to set up and maintain, issues like checking for interface matching are of very low importance. Basically, I want to broadcast a message on the local network and retrieve all answering IPs. So my first idea is ...
Ok, not really sure how to word, but will try my best. I have a number of WCF services that are setup and run awaiting an object to come in for processing. WCFServiceA WCFServiceB WCFServiceC Service A will run some processing and decide to send the object onto Service B or C. So my object has [DataContract] attribute on all classes...
Hello, I am trying to run simple application (e.g. generated from template by VS.NET 2010) on IIS6. I changed it to run with .NET 4.0 (its application pool) and checked with regiis (this pool has 4.0). I also changed all possible httpHandlers (svc etc), to run with NET4.0. All possible rights are checked (i think so). Almost every requ...

The generated proxy code has a class for the reason element containing (among other things) properties nullFlavor and typeCode....
Hi guys. We have a WCF service self-hosted in a Windows Service. Right now we're experiencing a really strange behavior with it, which is that every 23 hours, approximately, the service raises an exception for every call made to it with the following error: Server was unable to process request. ---> The request channel timed out whil...
Assuming that the service is running and in use, and you didn't change the contract or anything - just some underlying logic. After publishing the service to IIS, do you have to restart IIS? (If it matters, the InstanceContextMode is Single) Are there any instances where you would/would not need to? ...
WCF allows you to specify an external WSDL file that should be published with the service rather than WCF's generated WSDL. In a WSDL-first design approach, it makes a lot of sense to publish the source WSDL rather than the generated WSDL. This is set using the externalMetadataLocation: <serviceBehaviors> <behavior> <serviceMeta...
