Later today you’ll be able to download the Open XML SDK v1 (currently the April CTP – make sure it’s changed before you download!). This release includes a set of APIs designed for manipulating Open XML format documents at the part level (ie wrapping a lot of the lower level System.IO.Packaging APIs) as well as samples and documentation. There will be a CTP of v2 of the SDK available later in the summer which offers higher level APIs targetted at the specifica of WordprocessingML, SpreadsheetML etc
