You are probably wondering what are our plans regarding Workbox compatibility with SharePoint 14.
The general answer is that we are definitely going to support SP2010 and we want to have it ready for the official release of SP14. Probably we will start some R&D next week, but we cannot promise the SP 14 compatible version this year.
Availability of Workbox for SP2010 depends on how much changes Microsoft
has made in the API. We will need to change the references from the SP
12 to the SP 14 DLLs, but we are not sure if Microsoft pledge, that old application will work can
be taken literally. The amount of work depends how many things we will need to adjust to the new API. We will post new information as soon as we know more on this issue.
