I am going to be coming up with a design for calling WCF services from our WPF front end clients. One thing I really don't like is the tight coupling of a WCF service's configuration to the client. I have read a couple of articles on ws-discovery in .NET 4 and was wondering whether this would be a common model that people use for handlin...
Hey guys, I have a WPF application which tightly coupled to linq2sql through WCF. It now turns out the Customer would like some sort of Offline mode using an xml file structure.

I have a WCF service which provides a method that creates a file. Sometimes it takes a little while for this file to appear, and other methods which are relying on that file's existence fail if they are called immediately afterward. As a result, I want to check that the file has appeared before proceeding. In my client class, I can call...

I would have thought that there is a lot of information out there on this, but I haven't found anything that really answers my question. What are the advantages of making an EJB rather than a web service? The only clear advantage I can come up with is performance. Even so, I can't find any hard data on how much more efficient EJBs are. ...
Hi, We are trying to create a "proxy" class that would serve the WCF service with its configuration properties. Because we can't store those properties in the app.config file, i'm looking for a way to "proxy" it out and use custom configurationSection which would provide all these data upon request. In order to do so, i would need to ...
I'm writing a .NET 3.5 app and have control over both the WCF service and client. I'm using svcutil to generate proxy classes for my services, combining several services since they share data types. svcutil /out:ServiceReference.cs /noconfig /namespace:*,Global.ServiceReference /tcv:Version35 http://localhost:12345/first.svc http://loc...

What's the best way to handle adding a new (optional) parameter to an existing opertion without requiring the client to update their WSDL? I do not want to update the namespace to describe a new version of the service contracts, since this should be backwards compatible with older clients. Should I add a new operation with a new paramet...
I have read several articles on what needs to be done to successfully host a WCF service on GoDaddy. --UPDATE-- I've abandoned the GoDaddy hosting option, and am hosting this with FluidHosting.com. They seem pretty solid, and all the issues below are still valid... --END UPDATE-- I have since implemented these: adding remove name......
I'm able to call a 3rd party vendor's web service from a Windows form program just fine. When I try to call the same web service and web method and same URL from a WCF web service I get the following error: ExportValuationPolicyNumber:Exception=System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.Soc...
Hi I need to populate a table B by selecting a from table A but for every single record selected from Table A for some of the fields I need to pass it to a WCF webservice and do some tasks. Can somebody show me an example on how to invoke a WCF webservice for every single row fetched from a database through a script component A step b...
Genuine Channels is a set of 3rd party chancels for .Net Remoting. I have been given the tasks of replace the usages of .Net Remoting in a rick client and server with WCF. I am familiar with standard .net remoting but not Genuine Channels. So what problems should I expect and any pointers to the solutions? ...
I have a WCF REST service that among others saves/deletes files and folders on the server. To be able to access data on the server I impersonate a user that has credential for writing/deleting from the servers hard-disk. Things work alright until i want to do 2 DELETEs in a row. Meaning a call "foo.svc/bar/1" with DELETE method it works...

I'm doing testing against some software I've written. The test enqueues messages into MSMQ via WCF at a rate faster than than my software can dequeue and process them. This shouldn't be a problem, since that is MSMQ's intended purpose, but if I enqueue enough messages to where it's taking my software more than 24 hours to process, thos...
I believe Jimmy Nillson said he generally made his webservices singletons. Is this the preferred method, and with WCF? Other than making the service methods static, is there something else to be done? ...
Doesn't configuring WCF in code require more coupling with the model and service libraries? If I'm understanding it correctly, you configure the host in code in the same project as the utilized services. Then configure the channel on the client, but the client then has to know about the model which means if I have several client apps u...
