Overview of usefull developer tools in 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:

• REST is not a protocol, it's not a standard, it's an architectural design.
• It's a simple guidance that builds systems that focus on a resource centric approach.
• Data organized as addressable resources. Uniform interface to act on them.

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.
