My WCF Service has an OperationContract that accepts, as a parameter, an array of objects. This can potentially be quite large. After looking for fixes for Bad Request: 400, I found the real reason: the maximum message size. I know this question has been asked before in MANY places. I've tried what everyone says: "Increase the sizes ...
While I'm making SOAP or REST invocations to WCF, I'd like to have the channel stack on either end (client and server) record the on-the-wire size of the data received.

Hi, I'm having an issue when trying to access a WCF service behind an ISA Firewall 2004. Apparently my Windows client can connect and receive data when using Buffered mode but not when using Streamed mode.

I'm using SL 4 and a .net-4 WCF service with a PollingDuplexHttpBinding. Calling the service and calling the client back from the service works fine. But as soon as I call the service, say 15 times without waiting for the async answer, I receive a TargetInvocationException after getting 0, 1 or 2 successful answers. My attributes for th...

Hi everyone, I'm writing what I'm referring to as a POJ (Plain Old JSON) WCF web service - one that takes and emits standard JSON with none of the crap that ASP.NET Ajax likes to add to it. It seems that there are three steps to accomplish this: Change "enableWebScript" to "webHttp" in the endpoint's tag Decorate the method with [We...

Been working on this a couple of days now. We're starting a LOB app with Silverlight and we're running into a big obstacle right away. Began using Fiddler to examine what was going on and found out something very interesting. Any queries (IQueryable functions on the server solution) that return more than 1.5MB of data will fail with t...
