SharePoint 2010 Sneak Peeks - Developers

Visual Studio 2010 Sharepoint Tools
This is an equivalent product to the VSeWSS. Here are the tools:

• Import VSeWSS Project
• Import Reusable Workflow
• List Definition
• Sequential Workflow
• Content Type
• BDC Model (Application Definition)
• Module
• Empty Project
• Event Receiver
• State Machine Workflow
• Import SharePoint Solution Package
• Visual Web Part

VS 2010 Server Explorer can drill-down into sites with "Folder List"-like structure. You can see lists, libraries, etc. exactly like the Folder List in SharePoint Designer. The VS Debugger can now attach to a Sharepoint site, and you can establish breakpoints in your aspx runtime. A demonstration showed a webpart which, when viewed, transferred control back to Visual Studio and stopped execution at the breakpoint!

Also, a Developer Dashboard control is on the SharePoint pages (an icon) which refreshed the page and displayed a pane containing server information, database query statistics, event reports, web part rendering times, etc. I would imagine that this control is only available if debugging is enabled in the web.config file.

Client OM
A Client Object Model is provided as an abstraction into client-side processing functions (AJAX, JavaScript, Silverlight, etc.). Part of this library is a ClientContext datatype, which presumably keeps track of the site as it is manipulated by client-side functions. A ClientContext.ExecuteQuery method was shown to query a database (in a Silverlight web part) based on infomation kept in the client.
