In my new WPF/silverlight app, is it better to directly connect to my remote SQL Server (I'm using linq to sql), or is it better to call a WCF service and have the service connect to the database? The SQL Server and a Win2k8 web server are both leased and at the same location. If creating a WCF service, I would run it on the web serve...
I have a WCF 3.5 service and it runs great. It is using basicHttpBinding and IIS 7 hosted. I'd like to add some minimal security to it, maybe a username and a password. Can someone give me some really basic instructions? What do I need to add to my web.config file? ...
My WCF service uses netTcpBinding, and has a callback object. I need to service multiple concurrent clients, and mantain sessions, so the service is decorated with [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession, ConcurrencyMode = ConcurrencyMode.Multiple] To avoid thread deadlocks, the callback class is decorated...
I'm trying to build a light-weight SOAP client without using Add Service Reference. Ideally, this client should work for as many services as possible. Currently, it uses ServiceDescriptionImporter to generate the service assembly. Unfortunately, this doesn't appear to work for WCF services. Someone recommended that I use ServiceContractG...
I'm new to the WCF, and I'm looking for some advice. In my web app I consumed a web service (R+Click on project - "Add Web Reference") and started coding. My web app is really big, so it was taking forever to compile each time I wanted to debug, so I built a stripped down WinForm using the same code. In VS2008 there is no "Add Web Ref...
I've got this Silverlight Prism application that is using MVVM. The model calls a WCF service and a list of data is returned. The ViewModel is bound to the View, so the ViewModel should have a List property. Were should I keep data returned by a WCF service in MVVM? Should the List property be calling into the Model using its gette...
I'm trying to use NeoLoad to generate and execute SOAP requests and upon supplying the WSDL, it doesn't seem to like the imports that they are referring to. I'm thinking I would need to flatten the WSDL generated by the WCF service. Are there any techniques I could use to flatten it? I've been reading: http://blogs.msdn.com/dotnetint...

I created a project as a Class Library. Now I need to make it into a WCF. I can create a WCF project, but I would like to avoid all that fuss with TFS. I've done the App.config and added the /client:"wcfTestClient.exe" line to the Command line arguments. But there seems to be something else missing from it launching the Hosting. ...

WCF is supposed to be better then a web service so I am assuming that there is a better way to do things. 1) How do I maintain session and call a web service that uses session? 2)...

When each console is started, it creates a new self hosted instance of the "P2PService". It then creates a nother instance of the P2PService, establishes a duplex chann...
