We've recently upgrade from CRM 2011 to CRM 2015. A Silverlight component (I know but we're stuck with it) has a section in it which displays a CRM search dialog. Since the upgrade the dialog doesn't return any data?
if (ReturnedParams == null) { HtmlPage.Window.Alert("ReturnedParams == null"); -- ALLWAYS GETS TO HERE } else { HtmlPage.Window.Alert("ReturnedParams IS NOT NULL"); }
