Hi All I'm using WCF to connect to a remote web service (asmx) for testing at this point. The remote web service is unsecured for now (no https, no user name, password). I can add the WCF service reference, and all the classes are generated ok. When I make the call to the webservice, it just hangs. So I can connect with the SOAP UI t...

I have a single instance WCF service class that is self hosted using a Windows service. I set up the service host in the OnStart event and I close the service in the OnStop event. In the service class I implement a destructor and I have some clean-up code in there. Essentially the clean-up code serialises some internal objects to disk f...

I'm trying to use a WCF service to fulfill MS Ajax AutoCompleteExtender completion list. I tried two alternatives. If I add a WCF service in my website project, AutoCompleteExtender calls it thriugh POST and it works fine.

I'm new to WCF services and wondered what the best way to tackle the following would be. I have many clients (~200 - ~500) that are all making requests of my service fairly constantly during the working day. Most requests involve interrogation of an underlying database to feed the correct response back. What I'm concerned with is the p...
I have a WCF client proxy which reads from a SOAP web service. I do not control the service, only the client proxy. The result of invoking one of the operations of the service is defined as a very large XML schema, of which only a small subset is relevant in my application. I have created a custom WCF behavior which allows me to parse t...
I'm hosting my WCF application with IIS. To serve some methods I need a reference to helper object which is heavily initialized. A good scenario is to initialise it once and put in a cache, then all requests just use the object from cache. How can I do caching? The easyiest way is to use static field of mywebmethod. IIS creates several ...
The only time we notice this value appears to be when the service crashes because the value is too low. The quick way to fix this is to set it to some very large number. Then no problem. What I was wondering about is are there any negative consiquences to setting this value high? I can see that it can potentially give some protection f...

I'm developing an application that does some CRUD operations through a WCF service. The read method returns a complete entity, the update is performed through a legacy system, and only the changed values should be updated. What is the best way to design the data contract for this scenario without simply sending a dictionary of key-value...
I have a WCF service (hosted by IIS webpage) that is working but I want to write more info out to a log file. I inherited code and it had some simple logging to a file. That worked on the original developers machine but I don't get anything written out. Note it reads the log file path from the config which I assume was the web config...
It's been a few years since I've done web services. I remember it to be fairly simply to create and consume one. In my current position, I work in a large organization and we use a lot of DB2 stored procedures the mainframe guy write for us to get at HR data. I'm now starting on a new HR project and rather than having the same ol' data...
I'm trying to consume a RESTful web service using WCF. I have no control over the format of the web service, so I have to make a few workarounds here and there. One major problem I cannot seem to get around, however, is how to make WCF deserialize an enum as a string. This is my code (names changed, obviously): [DataContract] public en...
I am getting a "The message could not be processed..." error from a WCF client. Please help, it's killing me. I have a test win app that goes through a for loop to kick of x number of asynchronous calls. Each asynchronous call instantiates its own instance of a WCF proxy and calls a WCF service using that proxy. If x is about 35 or l...
