My colleague Rich Olivieri offers this summary of SharePoint 2010 Points live from the Microsoft SharePoint Conference in Las Vegas:
- Support for developing on a client OS so long as it is 64bit Windows 7 or 64 bit Vista SP1.
- API available through REST. You can call listdata.svc and get a strongly typed response vs a weakly typed response from lists.asmx. It is WCF REST combined with ADO Data Services.
- You can link lists through a look up column and pull in multiple columns from the other list for display.
- Sandboxed solutions – more a thing for IT…it limits the sandboxed solution access to the object model that is directly related to a specific site collection.
- SharePoint Online 2010 now allows deployment of custom code.
- SharePoint Designer 2010 has increased support for developing deployable workflows (deployed as wsp) and BDC entities.
- Remote Blob Storage – now you can store those really large binary files some place other than SQL.
- Performance enhancements – throttling and large list control. SP 2010 now supports 50 million items within a SP list, but you can configure per web application settings to limit max sizes of query results (default 5,000) and send warnings out when list reach a certain size (default is 3,000). Overrides are available for object model access and PowerShell commands.
- New PowerShell CMDLETS (command-let) represent functions that can be used separately or combined with other cmdlets to script complex SP administration tasks.
- Public beta is in November.
- Upgrades: Existing 2007 should upgrade as is to the new infrastructure. Then by use of a visual upgrade tools IT/Dev/Users can decide to upgrade to the new UI.
- REST Services: RSS feeds probably now second to REST Feedservices using AtomPub…this is down to item resources.
- In page edting of things like Site Titles and Site Images….can use Wiki style editing tags for links like [[this document:document link]]
- Offline editing and use of SP items via SharePoint Workspaces..the replacement for Grove.
- CoEditing of documents…close to Google Docs.
- Semantic Search…going to that session.
