I have an operation contract (below) that I want to allow GET and POST requests against. How can I tell WCF to accept both types of requests for a single OperationContract?

We have a WCF service with multiple TCP endpoints. I am interested in monitoring the total number of concurrent open connections at any given time. Are there any perfmon counters that will allow us to do this out of the box? Note that number of instances != number of connections in our case. ...
I'm trying to make a WCF service that will work with JSON-P (long-story short, we have to call the web-service cross-domain and receive a call-back, so I need it to work with JSON-P). I found a code-sample on MSDN (http://msdn.microsoft.com/en-us/library/cc716898.aspx). If I extract the ZIP file and navigate to Samples\WCFWFCardSpace\WC...
Is it possible to do a cross-site call, in Javascript, to a WCF service? I don't mind if it's a POST or a GET. But I've heard that these days, browsers don't allow cross-site calls with either POST or GET. How can I circumvent this and still call a WCF Service? ...
Hello !! I have a wcf service where i have to implement the call backs and also i need to host the wcf service on the IIS 6.0, since IIS6.0 doesnot support the net.tcp binding, i decided to go for the custom binding.

Hello, After implementing Nh.Burrow in an asp.net application, I was wondering how to do it for a WCF-service. My first idea was to put a the BurrowFramework().InitWorkSpace(); in each method and set the InstanceContextMode to per Call on these methods. Now I have two questions: Are there better methods to combine Nh.Burrow with WCF?...

We are running a service that requires fast communication with another process. Currently we are using WCF NetNamedPipeBinding in buffered mode to invoke methods in the service, which seems to offer the least overhead of the available WCF bindings. Is there a faster way to do this using managed code? Edit: Bunching requests as suggested...
In wcf, what is the difference between applying the DataMember attribute on a property private int m_SomeValue; [DataMember] public int SomeValue { get {...} set {...} } instead of a member variable [DataMember] private int m_SomeValue; public int SomeValue { get {...} set {...} } ? ...
What is the best / most flexible way to have WCF output XHTML? If there is no "WCF Way" (tm) to do XHTML output - is there any common tooling out there for it? Or do I need to roll my own? ...
Hi, I am currently working on a small project, where I need to send a potentially large file over the internet. After some debating I decided to go with the streaming option instead of a chunking approach. The files can potentially be very big, I don't really want to specify an exact upper bound, 2GB maybe 4GB, who knows. Naturally th...
I'm in the middle of performance testing a critical section of my project, when I notice a whole lot of extra threads being used to to perform WaitOrTimerCallback operations. On closer inspection I can see that these are being spawned by my ASMX client proxy class for operations on a remote server. I was under the impression that t...
This is a though on to explain, here i go. We are creating a program where sender and receiver of the msmq is using WCF.

I've written a WCF duplex service and client. Everything works well until I try to call .Demand() in the client implementation. It appears that the the service invokes the callback method Anonymously. I think I am missing how to correctly configure the service. Code used to create ServiceHost; ServiceHost duplex = new ServiceHost(ne...
Besides using Web Services, or POX (or custom HTTP), are there some other techniques that I could utilize for calling services exposed from WCF via _______ to the Java world? These requests will be in the same machine. Maybe RAW TCP/IP? I'm just inquiring for a project that we need to possible provide some method of calling synchronou...
I built a web application containing a wcf service contract and a silverlight control which makes calls to that wcf service. On my development and test servers it works great. When I deploy to our live server and run the application I get an exception of type System.ServiceModel.ServiceActivationException which states that the service ...
