JervisProblem:
You ftp a Silverlight App to an IIS website, go to the website in a browser, and get the following error:
Message: Unhandled Error in Silverlight Application
Code: 2104
Category: InitializeError
Message: Could not download the Silverlight application. Check web server settings
Cause:
The Silverlight Mime types (.xaml, .xap and .xbap) are not listed in that websites registered mime types, therefore IIS will not send those files to the browser.
Solution:
Open IIS on the server, go to HTTP headers, click on Mime Types, click “Add New” and add the following:
Extension – Mime Type
.xaml – application/xaml+xml
.xap – application/x-silverlight-app
.xbap – application/x-ms-xbap
Hit Apply and your application will load! OR you can read another post from me, http://windows2008hosting.asphostportal.com/post/ASPNET-MVC-Hosting-ASPHostPortal-Unhandled-Error-in-Silverlight-Application-Code-2104.aspx
Hope it helps!!
