Ok, all these methods of getting data in a Silverlight control are confusing me. I've looked at ADO.Net Data Services, Web Service and Ailverlight-enabled WCF services. I'm just not sure when one is appropriate to use over another. What pros/cons do each offer? I've built a web app, and a silverlight control. I will be adding one of ...

I used to use .ASMX web services, but I'm trying to move to WCF because it's the latest newest thing, and it's supposed to be better. Anyway, what I'm wanting to do is really really simple : create a webservice that empties the Application collection by calling Application.Clear(). In an ASMX web service, this is really really simple, ...
We are in the process of designing a simple service-oriented architecture using WCF as the implementation framework. There are a handful of services that a few applications use. These services are mostly used internally, so a basic authentication and authorization scheme (such as Windows-based) is enough. We want, however, expose some o...

However, using svcutil to generate a proxy class does not give us a .net nullable DateTime property, so how best can we make the proxy class serialise the message to a SOAP message that does not contain the datetime element? ...
hey guys, a WCF question for you here: i have two services and am sending pretty chunky messages between them (~100kb).

Thus, to deal with such situations where i have to tr...

When I first startup a client that is calling a service there seem to be a lot of failures in the first calls. For instance I can watch the first say ten calls go through and then the next 200 calls f...
