  • Simultaneously calling multiple methods on a WCF service from Silverlight

    Ola Karlsson had to debug some performance issues in an existing Silverlight app and he decided to share with you this problem and its solution which is quite tricky.

    On start, the app would do a number of calls to different methods on a WCF service, this to populate the UI with the necessary data. Recently one of those services had been changed and was now taking quite a bit longer than it used to. This was resulting in quite a long loading time for the whole UI, which was set up so it wouldn’t let the user interact with anything, until all the service calls had finished.

    Overview

    In this article we’ll be looking at the concept of adding interactive Silverlight elements to existing Web pages to provide added rich features. We’ll be looking at creating an animated Silverlight panel which will slide in from the side of the browser window when a button is clicked.

    The somewhat tricky bit is that we want the panel to lie on top on the normal HTML content of the page and when when the Silverlight UI is slid out we want to be able to interact with the HTML instead.
