Is impossible insert the we开发者_如何学Cb browser in silverlight web, return error HRESULT: 0xC00CEE21.. i have updated silverlight 4, web and sdk but null..

Remark from MSDN: The WebBrowser control is intended for use in Silverlight applications that run outside the browser only.

It should normally come up like this:

The error on insertion is an indication that your SDK/Tools install is broken. I suggest you reinstall Silverlight and the Silverlight Tool 4 For VS2010 SDK.

Hopefully it will work again after reinstalling.

Please note you can only use the WebBrowser control in OOB mode.
