I'm trying to setup a new category and add it to an appointment, but when trying to follow this: http://www.infinitec.de/post/2011/07/28/Working-with-the-Master-Category-List%E2%80%93EWS-edition.aspx I get: 'MasterCategoryList' is not declared. It may be inaccessible due to its protection level.
I'm using Microsoft.Exchange.WebServices version 14.0.0.0.
I assume something's changed in the service since that article was posted, but I can't find anything useful in the docs :\ can anyone out there help!? :)
The MasterCategoryList isn't in the Managed API that is something Henning built so if you look at the download project include with hist post he has the classes you need to include in your project. In the Managed API you use the UserConfiguration classes.
