I am trying to write a Windows Service which will call web service methods based on a run schedule. I have setup a ‘schedule’ table which holds the name of the web service method and some scheduling details (e.g. run every day at 0200).
I am using VS 2005/vb.net.
My service creates a timer which runs every minute and when the timer is fired the schedule table is read and any entries which are due to fire are actioned. This could mean multiple methods being fired at the same time. As some of the
methods are overnight batch processes and may take some time, I don’t want processes to wait for others to finish before being actioned. As the methods themselves write to the system log to report their success or failure the scheduling service
does not care whether the job fails or not – it is simply doing a ‘fire and forget’ exercise.
What I need is some code which will fire a data-driven web service method asynchronously.
I have investigated two types of method call. The first is a simple InvokeMethod:-
mywebservice.GetType().InvokeMember(ScheduleRow("WebMethod").TOString(),(Reflection.BindingFlags.InvokeMethod Or Reflection.BindingFlags.IgnoreReturn), Nothing, mywebservice, Nothing)
The second is an asynchronous call:-
Dim asyncCall as New AsyncCallB
I would like to take WCF Data Service and produce JSON output to consume on various mobile apps.
Can anyone give me a how-to on the JSON part? I.e., what is different than normal XML outut?

Julie Lerman shows database administrators how to limit access to databases from the Entity Framework by allowing it to work only with views and stored procedures instead of tables-without impacting application code or alienating developers.
Smart client applications are responsive and promote interactivity with the user. In this article, we start the processes of planning and building a smart client application using NHibernate for data access and Rhino Service Bus for reliable communication with the server.
