Hi Alex,
Basically and likely the bottom line is No... It's an ActiveX control so not compatible with .NET Framework and/or IDE.
You may be able to use it in a Managed C++ app since you have more control on loading dll's and getting to the root set of API's but that would be a re-write also.
Bottom line is NO, upgrade to CR for VS SP 10, SP 12 will be out very soon. ( this week possibly )
Why do you need to use the old ActiveX viewer?
