As you may have heard, Silverlight 2 beta 2 came out. This post for me is necessary because I wrote a two part series on getting a Silverlight application to work in SharePoint, and since beta 2 came out, a few things need to be updated in that walkthrough of mine. Before I get started, MSDN has a nice article on all the main things that changed that could cause your applications to break – it's a laundry list so prepare for a heavy read.

Here's my laundry list of updates to my steps:

STEP 1:    You need to install the beta 2 extensions for visual studio, not beta 1 as I mentioned in Step 1. After you install it, just load your beta 1 project and it will prompt you to upgrade it. After it is upgraded, rebuild and redeploy the XAP file and now your application is beta 2. But there's a few more things to note…

STEP 4:    If you installed your Silverlight application like how I did, you just inputted the necessary HTML into a content editor web part. That HTML needs to be updated. The red highlighted text notes the updates from what was noted in step 4 of my 10 steps:

<div id="container">

        <div id="header">

            <div id='errorLocation' style="font-size: small;color: Gray;"></div>

<div id="silverlightControlHost">

        <object data="data:application/x-silverlight," type="application/x-silverlight-2-b2" width="100%" height="200px">

            <param name="source" value="/clientbin/SilverlightApplication1.xap"/>

            <param name="onerror" value="onSilverlightError" />

            <param name="background" value="white" />

            <a href="http://go.microsoft.com/fwlink/?LinkID=115261" style="text-decoration: none;">

            <img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight" style="border-style: none"/>

            </a>

        </object>

        <iframe style='visibility:hidden;height:0;width:0;border:0px'></iframe>

</div>

STEP 9:    Lastly, the error handling code also needs to be updated to be as follows:

<script type="text/javascript">

function onSilverlightError(sender, args) {

var appSource = "";

if (sender != null && sender != 0) {

appSource = sender.getHost().Source;

}

var errorType = args.ErrorType;

var iErrorCode = args.ErrorCode;

var errMsg = "Unhandled Error in Silverlight 2 Application " + appSource + "\n" ;

errMsg += "Code: "+ iErrorCode + " \n";

errMsg += "Category: " + errorType + " \n";

errMsg += "Message: " + args.ErrorMessage + " \n";

if (errorType == "ParserError")

{

errMsg += "File: " + args.xamlFile + " \n";

errMsg += "Line: " + args.lineNumber + " \n";

errMsg += "Position: " + args.charPosition + " \n";

}

else if (errorType == "RuntimeError")

{

if (args.lineNumber != 0)

{

errMsg += "Line: " + args.lineNumber + " \n";

errMsg += "Position: " + args.charPosition + " \n";

}

errMsg += "MethodName: " + args.methodName + " \n";

}

throw new Error(errMsg);

}

</script>

That's all that needs to be updated to get our simple little Silverlight application to work. As I mentioned in the beginning, there are a lot of other things that changed, but our app is just a Hello World app, most of it isn't relevant to us.

Good luck!
