We are currently researching the possible options for distribution of the API Reference in second format, which includes both research towards providing compatibility for VS 2012, and possible options for another format export (CHM, HTML).
Currently the documentation gets compiled, and we're not able to get a hold of the intermediate HTML to provide you with, however please stay in touch as we progress with this task and will announce it once complete.
All the best,
the Telerik team
