I have a WCF service up and running and am able to communicate between the service and a .Net 2.0 Client using basicHttpBinding. I now need to lock down the WCF service so that it can only be called by authenticated clients. I have control over the clients that will be calling my service. The clients are part of a product that will b...
What is the best practice for writing a rather large wcf service, containing a lot of OperationContracts and DataContracts? How would I separate functional areas into several contracts, would it be best to create an endpoint for each functional area? Is there any way to keep the source for the different parts apart, but still use only...
This is a follow on to this question. I am trying to avoid using the x509 certificate method as that makes my client installs more complex. If basicHttpBinding is not the only option, where are some samples of other binding methods. My clients are on .Net 2.0, I don't have access to System.ServiceModel namespace as that didn't come ...

We have an R Server (R is a programming language used in statistical analysis) that basically takes a script and a csv file, processes some data and returns results as text. I need to write a service on the R server so that .net clients (could be .Net Windows Forms, or ASP.Net) can connect to the R server, submit the script and CSV fil...
I'm hosting my first WCF service in IIS. I have two methods, 1 to set a string variable on the WCF Service, and the other to retrieve it. The interface used is: [OperationContract] string ReturnText(); [OperationContract] void SetText(string s); BasicHttpBinding is used. Stepping through the service with the debugger from the client ...
Hello, I want to write a WCF service that can't run more than X times per hour. I want the service to suspended messages to a queue if the service was called more than x time in the last 60 minutes. Any ideas how can one limit the service? I am willing to write custom components in the WCF stack. ...
Hi, For an enterprise type WCF service, where potentially 10K's of thousands of clients will be authenticating and sending data to central servers, what is 'best' practice when it comes to sessions or authentication? does WCF support a session, if yes, should I use it? or should I simply pass username/password on a per call basis? ...

WCFTestClient tool doesn't seem to work if the size of maxNameTableCharCount is greater than default value (16384). Is there any way to modify the settings of the config file generated by this tool, BEFORE the tool generates it? I can modify the config file contents AFTER the service connection is established. But I am getting an er...
There was no endpoint listening at http;//localhost:8080/xdxservice/xdsrepository that could accept the message. This is often caused by an incorrect address or SOAP action. ...
Before I start, I know using iisreset is considered bad practice, but this shouldn't happen anyway.. What we have: Several machines with IIS6 on Windows Server 2003 R2 (both 64 and 32 bits) Several WCF webservices (.NET runtime 2.0) deployed in several applications, each with it's own application pool, each application pool running un...
My WCF Service uses wsHttpBinding and works fine from the client when the service is gerenated by the client using the default options as follows: RServiceClient R = new RServiceClient(); However, at some point I'll need to be able to specify the location of the service, presumably by changing the endpoint address as follows: ...
I have client application that uses WCF service to insert some data to backend database. Client application is going to call service on per event basis (it can be every hour or every second). I'm wondering what's the best way of calling that service. Should I create communication channel and keep it open all the time, or should I clos...
I like using WCF callbacks when I can because to me it is better than the client having to poll the server and its more real time than polling. The question I have is when I subscribe to a WCF service event is there any kind of heart beat that keeps the connection alive between the client and the server. I starting to think that there is...
Is it possible to have multiple listeners to messages carried by MSMQ? WCF appears to frame everything in terms of services, making communication a point-to-point affair. I want to use a message queue to buffer incoming traffic for another process that records the logs in a database. There can be be any number of other processes inter...
