I haven't deployed behind a load balancer before. My customer has a WCF service built and tested on servers using a service model configuration that is relatively straightforward. It provides a service to return an image of a map for another application. To get the map, it calls other services. The service was built in Visual Studio 201...

Apologies if this has been asked before, but I've searched and can't find an answer We have a WCF service that provides upto 100 instances - as there are 10,000 clients but the calls are very quick.

Today, I implemented a custom authentication provider for my WCF service. It is able to determine if my user is valid or not, just as expected. So, now I have this class: public class MyCustomValidator : UserNamePasswordValidator { public override void Validate(string userName, string password) { User apiUser = User.Log...

Hi all, I have created a BizTalk orchestration that sents a message to a wcf webservice, the webservice creates a task on sharepoint, and the orchestration receives a response (just a string "succes"). Now I also created an eventhandler in sharepoint when someone changes a task to "complete" some code can be executed. I want to be able ...

Hi all, I have a collection of WCF web services that share a common DTO model. The problem is that when I add service references in Visual Studio 2010, the proxy generated for each of the web services has its own namespace (internal to the solution), meaning that I essentially have duplicate DTO's on each of the service references. I...

I'd like to be able to create standard POCO service that I can use in two distinct workflows: in-process i.e. consumed by my ASP.NET webforms application remotely via an exposed WCF endpoint to be consumed by other applications Is there a way to re-use the same service and its return data types in both scenarios above? Ideally, my co...
I'm designing a WCF service that will return a response code (such as 0 for success, or another number for errors). Also, all methods of the web service will perform several common validations (such as authenticating an apiKey). I am wondering if there is a best practice approach or organizing and retrieving these response codes and mes...
I've created and configured an SSL certificate as per these instructions from MSDN. I'm getting the error message that this question lists, but am not sure how to map the accepted answer in that question to my App.config file. The content of the config file, and the service itself worked correctly over http, it's just over https that the...
I'm experimenting with writing Javascript/JSONP queries against an WCF oData API. For performance reasons, I'm trying to keep the responses succinct. The default seems to be for the oData endpoint to return uri and type metadata with every returned result. This information can take up a significant portion of response payload. Is there a...
I'm on the process of creating an API in much the same way Hanselman showed it could be done for Stackoverflow. I have a bunch EntityObject Entity Framework generated classes and a DataService thingy to serialize them to Atom and JSON. I would like to expose some generated properties via the web service. Think FullName as generated by co...
