Did you know you can decompile Silverlight apps? As with ever other .NET app, if you have the assemblies you can pretty much load them into reflector and view the source.

So when it comes to silverlight how do you get the assemblies in the first place? Well it turns out when you develop your app all the assemblies are packages into a XAP file which is then downloaded to the client.

An XAP is actually just a zip file with a different extension. Therefore, all you need to do is the following.

1.) Locate the XAP file on a web page or file system by looking at the source.

2.) Place into the browser and download the XAP package.

3.) Once downloaded, change the XAP extension to .ZIP

4.) Extract the package using whichever tool you like. I use WINRAR.

5.) Locate the assemblies in reflector and view the source.
