Demonstrate best method for an outside process to trigger events inside Silverlight apps running in browsers. I do not want the Silverlight app “polling?? on a timeslot. Rather I want the outside process to cause an event to be fired in the Silverlight app when something occurs. A practical simple example is:
- IP capable door alarm device in remote building connected to Internet.
- Security dispatchers at a remote location run Silverlight application in their web browser
- When alarm is tripped, a message pops up in the Silverlight app for all web users
... you will make a sample VB.NET\VS2008 desktop app to simulate the alarm, with three buttons on it to simulate three different alarms. You will make a silverlight 3 \ VB.NET app for running in web browsers that just has a textblock on it that changes to display the alarm message whenever a user presses an alarm button on the alarm app. I assume you may need to make an ASP.NET or WCF web service to facilitate communications in the middle.
