Hi Don,
Indeed, we have plans to integrate RadControls for WinForms documentation in Visual Studio 2010, but currently we do not have a time frame specified for that. At this time, we are integrated with Visual Studio 2005 and Visual Studio 2008 only.
As to the chm file, you are probably experiencing the security issue described in
this Microsoft KB artcle. You can work around it simply by unchecking the "Always ask before opening this file" checkbox.
I would suggest that you directly follow our
online documentation as it is updated on a weekly basis.
Kind regards,
Nikolay
the Telerik team
