Maybe this is an obvious question, maybe it isn't. Imagine a GUI control application where every button push calls a different function on a remote WCF service. Button usage is frequent at approximately every few seconds. In general is it best to open and close the WCF channel every function call or hold the channel open for the lifetime...
We are hosting a net.msmq service in IIS7. The queue is transactional. Messages arrive in the queue and are picked up correctly by the service. If an exception occurs, message is put into the retry queue. The retry delay is set to 1 hour, however when this time elapses the message is not "re-tried". If we browse to the .svc or send an...
What does it mean for a ChannelFactory to have a State property? I understand that a created channel can have connection based states. But am confused as to why the ChannelFactory also has such connection states. Does it too connect to the WCF service? ...

Hi, Is that better to use WCF REST Starter Kit for consuming web services (REST) with WCF (by using HTTPClient) or do it directly with WCF ? It seems that WCF REST Starter kit won't be available for .NET 4.0 and is a preview version only. Thanks ! ...
Hello there, I have two base addresses defined in my WCF Service config file: <?xml version="1.0" encoding="utf-8" ?> <configuration> <!-- When deploying the service library project, the content of the config file must be added to the host's app.config file. System.Configuration does not support config files for libraries. --...
I want to use automapper with a structure that uses WCF + DTO's but I want to know how the question of the eager loading with entity framework 4.0 work with the mappings of the automap. ...
We've observed that when we expose a WCF service which uses classes decorated with various xml serialisation attributes, despite the fact that we use the XmlSerializerFormat attribute on the interface any XmlRoot attribute on any of the operation's parameters gets completely ignored. The namespace of the parameters is always that of the...
Hello, I'm having a problem using a WCF call from a Windows service to my WCF service running on my web server. This call has been working for a number of weeks, but then stopped working all of a sudden, and has not worked since. The exception I'm getting is: "General Error Occurred System.ServiceModel.CommunicationException: An erro...
I've written a WCF IDispatchMessageInspector, so I can log incomming and outgoing messages. But I'm not sure how to get a nicely-formatted XML string to log. My code looks something like this: public object AfterReceiveRequest(ref Message request, IClientChannel channel, InstanceContext instanceContext) { MessageBuf...
Is it possible to configure a WCF proxy such that it is able to understand SOAP 1.1 and SOAP 1.2 messages at the same time? In other words, I want to be able to connect to a web service that may return at any time, SOAP 1.1 or 1.2 based messages. Thanks. ...
I'm connecting a WCF client to a group of services all implementing the same contract and all at the same host. I was hoping that there would be a way to combine the endpoint definitions to cut down on configuration clutter. I also would rather not do it programmaticly - just by configuration. Right now, my config has this repeated ma...
I'm switching code generators for my business objects. I was using SQL Metal, but in moving to the T4 toolbox's generator, serialization seems to have stopped working, and it looks like the two are doing pretty much the same thing. This is the property generated by SQL Metal (which works): [Association(Name="FK_FamilyConfiguration_Fam...

It seems the world is awash with people having problems deploying RIA WCF services, and now I'm one too. I've already tried a bunch of things, but to no avail. I need WCF RIA to support a Silverlight 3 application I've built. The short story is, using the new WCF RIA services (Nov 09?) I open VS 2008, create new project (silverlight a...

Say if a user enters in a value and I need to check this value against the database to see if it exists and if so return an error and highlight the fie...
I've been studying the PeerChannel in WCF. The docs indicate that a peer will automatically try to get between 3 and 7 connected neighbors. My scenario is a couple of systems on one side of an expensive, high-latency connection; and one or more on the other side. Since the connection has limited bandwidth, I'd really like to keep cont...
