We have been using asp.net mvc razor technology as a template engine to allow the user to develop razor scripts on the client. we are using this for email template engine.

You can see example at Ricks blog on that

I was wondering if anyone know of a WYSIWYG style editor for the client browser that we can use instead of just a TextArea? Something similar to Visual Studio editor that show razor syntax etc..

Thanks,
