SharePoint 2010 Developer Overview

SharePoint 2010 Developer Overview by Mr. Srikanth Kothakanti, to help the SharePoint Community to quickly get on board with SharePoint 2010.


SharePoint 2010 Developer Overview:
  • The trick is that Visual Studio is 32-bit and SharePoint is 64-bit, so if you want Visual Studio to execute SharePoint operations, you need to use a special SharePointCommand type that will marshal the code for you for execution in a 64-bit thread. The Client OM would be a simpler option if you don't need to elevate permissions.
  • SharePoint 2010 can be installed on Windows 7 or Vista SP1
  • Windows SharePoint Server is now SharePoint Foundation Server
  • Still it runs on 64bit
Visual Studio 2010:
  • Package and Deploy
  • Can view SharePoint site via the Server Explorer
  • TFS integration
  • Sandbox support, WSP Import (nice)
  • BDC becomes BCS (Business Connectivity Services)
  • Both SPD and Visual Studio 2010 read and write same, i.e. if you send any .wsp package it will pick it up.
  •  All OOB web parts in SP2010 are public and no longer sealed. So now devs can extend all existing web parts
SharePoint Desginer 2010:
  • Will remain free
  • SharePoint Designer 2010 will not work with SharePoint 2007.
  • It is a completely new runtime.
  • FrontPage functionality hangovers either hidden or removed.
  • Workflow Designer
  • SharePoint Designer 2010 keeps tracks of every single change, so that means versioning is always on.
  • It also does not allow you to customize (or unghost) webpart pages by default. You have to open up the page in Advanced Edit Mode.
  •  Skewer Click: It's new feature by dragging it from the ribbon onto a cell in the DVWP and you will be able to see all of the elements parents

SharePoint List Improvements:
  • Can create relationships between lists.
  • This is piggy backing on SQL functionality
  • Validation support, Excel like formulas
  • Lookup to multiple columns,
  • Automatically create indexes where they make sense (for example on lookups)
  • No need to worry for 2,000 Item Limit, Example 220,000 item lists.
  • Views will use XSLT.
  • Throttling will block queries that are made for large numbers of items (configurable) 
JQuery in SharePoint 2010:
  • JQuery is now hosted on SharePoint 2010.
  • JQuery.sparklines.js plugin is included which will allows you to create contextually sensitive charts and graphs.
  • JQuery plugin for Firebug called FireQuery is being used.
  • A “sparklines” class is added to each row of the DVWP to be able to add the sparklines plugin to show a line graph next to each project item based upon its sequence column. The sequence column just as a comma delimited series of integers.
REST in SharePoint 2010:

Accessing Data in Lists:
  • Server Object Model which is already present in 2007
  • New: Client OM –> Runs on the desktop
  • New: REST API’s –> ATOM response
  • New: LINQ and all LINQ goodness
  • Supports Joins and Projections
  • If you want to work with relationships between items, REST and LINQ are much easier to use than the OM.
  • Use Server Object Model and LINQ to SharePoint when you are developing on the server.
  • Use Client Object Model and REST when running the code on a remote computer.
  • Will dramatically reduce run time errors, moving them to compile time
Query Throttling:
  • Site collection administrator can put a limit on the query block i.e. x number to be blocked
  • Developer can override the querythrottlingblock to retrieve more items from the server.
Resource Throttling:
  • Pagination plays a distinct role so that the data is filtered on the server, not on the client side anymore.
