Unfortunately, that won't be available until VS.NET 2005 comes out. They do have a native web browser control included with the framework. But, to be honest with you - unless someone at M$ took it on as a hobbie to re-write I.E. in .NET I can bet my left.... ahem! Well you know? ...the "native" browser control is probably using the unmanaged activex control.
The nice thing is that as long as you're distributing out to Windows XP or later Clients your code will work regardless you redistribute the control or not.
