Today Microsoft released a new technical preview containing a small chm file with more information concerning the SharePoint vNext.
You can download the SDK from here, note that is not final and can be updated or changed…
A brief overview of what we could expect:
Represents the Information Rights Management (IRM) settings for file downloads in Microsoft SharePoint Foundation.
Represents set of language preferences. The SPLanguageSettings object can be accessed via the SPUser object to return user’s language preference.
Describes a specific validation failure when a list item is inserted or updated.
Facebook Platform uses the OAuth 2.0 protocol for authentication and authorization, just like the Google API, Foursquare and Yammer…
But I’m sure more external systems are available and support this protocol…
Manages all the resource content that may be registered on a SharePoint page, including script files, inline scripts, style files, inline styles, and hidden input fields. Spweb ensures that the content can be either appropriately placed on a fully-rendered HTML page or correctly transmitted to a browser in the case of a partial page load.
I hope more will be available soon!
