Find the next TCP port in .Net says how to do this in raw .net, but not how to safely to this with WCF. In my unit tests, I need to use the NetTcpBinding, I do not wish to hard code the port it is using. Therefore how can I get the NetTcpBinding to automatically choose a free port when used in my ServiceHost? How can I get it to tel...
I am very new to WCF and have nil knowledge about this technology or whatsoever.I just wanted to know how a client will use this. I mean suppose an application has been well-built by programmers.Now coming to deployment, do we need to deploy it on server and again do we need to install something on client machine too for successfully run...
I have an ADO.NET Data Service and a regular WCF service. I'm using both these services in a Silverlight application. The WCF sercvice has an operation which has a parameter of the same type as an entity returned by the ADO.NET Data Service. The problem is that silverlight generates different types for the WCF service and for the ADO.NE...
Hi all, I'm wondering if it is possible to create a custom WCF binding. I want to simulate msmq using a set of database tables to achieve the same principle. There is a lot of negative attention attached to MSMQ at the company where I work due to previous projects that failed attempting to use it. I myself have never had an issue whe...
It is easy to do Asynchronous calls if the client proxy is created with “add service reference”, just call the “BeginMyMethod()” and “EndMyMethod()” calls on the generated client interface. However what you I do when I am used an interface that is defined in shared contract assemblies? E.g. the interface only contains “MyMethod()...
I have an asp.net 3.5 site and I've just written some wcf services. It is ok to just drop the .svc file right alongside my .aspx files or should I move my .svc files onto a separate virtual directory and IP and call it something like services.mydomain.com. Just wondering what best practices are. Maybe it doesn't make any difference? ...

I have googled around and just found reams of pages about how to set up a WCF service config which isn't what I want lol. Basically, I have a factory class within my service which reads a Custom property from the config file to determine which Data Access Object to create, however, whenever I try to test it I get a NullReferenceExceptio...
This one is driving me crazy! I've just upgraded to VS2010 beta 2 and created a simple WCF service. In previous VS versions I could easily find and edit the name and contents of the SVC file from the default Service1.svc to whatever I wanted to (i.e. e.g. MyTestWCFService.svc). I'm trying to do this in VS2010 but; 1) Can't find the svc...

I am currently reading through a proposal, where this person is proposing to use WCF services to facilitate AJAX calls in a web application. They say that WCF can serialize data more efficiently. I personally have never considered going this approach. I have always liked calling MVC controllers using jQuery's AJAX functionality, and th...
I have a service accessible via http and net.pipe. It is being hosted in IIS 7 (Server 2008). I may be hosting different instances of this service for several customers on the same machine and hence the HTTP is setup with virtual hostnames etc. This is all working fine. I thought I would do similar for the net named pipe binding - using...

System.ServiceModel.CommunicationException: An error occurred while receiving the HTTP response to http://localhost:8080/Service. This could be due to the service endpoint binding not using the HTTP prot...
So as to enable aysc callbacks to the clients, I need to add the Begin/End methods to the interface that is defined as the CallbackContract on my service.
