I have a Silverlight 3 application which needs to call WCF service. The WCF service in turn calls an ASMX web service. When the WCF service call completes, the silverlight UI needs to be updated. WCF is being called in async. The thing is that the Silverlight app needs to call the WCF method(which later calls asmx internally) hundreds ...
I've recently discovered a way to implement RESTful services using Global.asax (by handling the Application_BeginRequest event). Basically, I am saying it is possible (and easy) to implement a RESTful web service in classic ASP.NET, without any need for WCF. It takes approximately 30 lines of code to figure out which method you want to ...

However if I want to update some changed grid row, the service data context UpdateObject is not working: DataServiceContext.UpdateObject(MyGrid.SelectedItem); foreach (Object item in DataServiceContext.Entities) { // } ...
I wish to develop a client-server application in .NET that functions as follows: Clients connect to a central server. The server needs to keep track of which clients are connecting, and it must allow only those it knows (I have a repository of allowed clients). This is because in my application, it's critical to know who all are presen...

Hello, for a while I wonder if it is a good idea to store some data in a singleton when writing a web-(or WCF)service. The goal is to reuse this information in different calls of the service. I wonder what's the lifetime of those singletons, because for example when the application pool is recycled, the singleton is gone. Next Question ...
I'm trying to create a simple RESTful interface to my data. I've created a WCF web service and decided to use LINQ to SQL to connect to the database. Instead of making simple pass through objects, I decided to try just serializing the objects created by my LINQ to SQL dbml. I changed the Serialization Mode of the dbml to Unidirectional t...
I have WCF services exposed using WebGet and WebInvoke that require the data to be wrapped in xml. I would prefer to be able to return raw data without it being wrapped in xml and also allow clients the ability to invoke my service without needing to wrap the request in xml. I'm serializing the data using protocol buffers and convertin...

Accessing the service from other tools like browser works. When I debug application in Visual Studio when the first call to the service is made below output i...

We have created a client-server system WCF, and implemented custom validator as described here: http://blogs.msdn.com/b/pedram/archive/2007/10/05/wcf-authentication-custom-username-and-password-validator.aspx . In order to enable username and password authentication server part must have a certificate. Following another tutorial, we've c...
My first question is, is it even possible to use a custom UserNamePasswordValidor with basicHttpBinding? I have a asp.net web site using Forms authentication and a custom membership provider. I realise that I could use the built in System.Web.ApplicationServices.AuthenticationService to authenticate my client (a WPF app) but I don't wa...
