In-Browser HTML

In Silverlight 4, we could use the WebBrowser control only in an “Out-of-Browser” application. This has changed in Silverlight 5 as we can now use the WebBrowser control in the browser (IE). It will however require that you make a few changes to your system. Let’s get started:

1) Update the registry – Locate the following keys:

If you running on a 32 bit machine,

HKEY_LOCAL_MACHINE\Software\Microsoft\Silverlight\

and if you are running on a 64-bit machine,

HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\Silverlight\

change the UpdateConsentMode from a 0 to 1.

2) Sign the XAP File - Right click on the Silverlight application and go to properties. Choose Signing and check the checkbox Sign the .XAP file. Now click on the button Create Test Certificate. Enter any password that you want and hit the OK button. Now click on the More Details button.

Click on the Install Certificate button. Clicking on the button brings up the Certificate Import wizard. Click on the Next button and choose Place all certificates in the following store. Click on the Browse button. This will show you a Certificate Store. Choose Trusted Publisher and finish the wizard. Now repeat the same step to install this certificate in Trusted Root Certification Authorities.
