SPC09: Overview of New Developer Features in SharePoint 2010

with 4 comments


At the SharePoint Conference in Las Vegas, Paul Andrew gave a thorough overview of the new features for developers in SharePoint 2010.

This is my modest attempt to convey Paul’s presentation in a simple blog post. Please note that the session contained a huge amount of information and I probably (definitely!) didn’t manage to take it all in. Read on at your own risk…


Development environment and tools

Traditionally, the path to your first SharePoint hello world-web part is littered with technical obstacles in the shape of tedious installation problems, Windows Server 2003 blues, virtual server nightmares etc. No more. Now you just need your laptop to develop SharePoint applications.

The box

SharePoint developers no longer need to run a Windows 2003 Server. In fact, SharePoint and the development tools can now be installed directly on Windows 7 or Vista (service pack 1). Either versions of SharePoint can be used, i.e. SharePoint Foundation (formerly WSS) or SharePoint Server.

The operating system must be 64 bit since SharePoint 2010 only runs in a 64 bit environment.

SharePoint on a desktop operating system is just for developers and not for running a production environment.


Visual Studio 2010

Many of SharePoint 2010’s new features can be accessed from inside Visual Studio 2010. Also, quite a few third-party add-ons may not be needed anymore as the functionality is now covered by Visual Studio.


  • Built-in designers for:
    • Web parts
    • BCS (formerly BDC)
    • Workflows
  • Package and deploy SharePoint projects
  • Generate WSPs
  • View SharePoint sites in server explorer
  • Integration to Team Foundation Server
  • Support for SharePoint sandboxed solutions
  • WSPs from SharePoint Designer can be imported (including workflows)
  • Build workflow steps for SharePoint Designer
  • SharePoint Business Connectivity Services support
  • New events projects templates


General improvents

Developer dashboard

A developer dashboard can be displayed automatically at the bottom of every page. The DD displays valuable information about how the page is generated, for instance:

  • Timing and duration of events
  • Database queries (even the ones SharePoint does in the background)

The DD is activated with the follow stsadm command:

stsadm –o setproperty –pn developer-dashboard –pv ondemand



Coding for SharePoint just got slightly easier due to the many improvements in .NET framework 4.0 and SharePoint 2010.

Below is a rundown of some of the new features:

  • LINQ for SharePoint
  • After-synchronous events
  • New event types:
    • Site-scoped events
    • Web creation events
  • Workflow improvements:
    • Initiation and association forms in Visual Studio
    • New design user interface for workflows in SharePoint Designer
    • Use Visio 2010 to design workflows
  • SharePoint UI can now be saved as a template
  • WSP is now the unified developer format – works in site collections and machine


Improvements to lists

In SharePoint 2007, lists can cause any developer headaches. Hopefully, the new list architecture in SharePoint 2010 will solve this. Below is an overview of some of the improvements:

  • Validation with Excel-like Formula – forms can be validated using simple syntax
  • Lookup to multiple columns
  • Lookup fields have true relations which ensure proper deletion (transaction-style)
  • List index auto-creation
  • Scalability and performance vastly improved:
    • Lists and folders can now contain a million elements
    • Document libraries can contain 10 million documents
  • List query throttling
  • Lists views no longer based on CAML but XSL-T. Queries still use CAML


Ribbon and Dialog framework

The ribbon we know (and some love) from Microsoft Office is now used in SharePoint 2010.

Some of the highlights:

  • Custom actions can be embedded in the ribbon
  • The ribbon is context sensitive
  • The SharePoint out-of-the-box forms are replaceable
  • New web dialog functionality:
    • A dialog floats on top of the SharePoint page and is used to get input from the user
    • Fully programmable


Silverlight 3

Silverlight plays an important part in SharePoint 2010 and is used in many of the improved UI elements. From a developer’s point of view, these are the highlights:

  • Built-it and customisable media player web part
  • List and site creation from within Silverlight
  • Office web applications run in Silverlight
  • Client object model – call SharePoint APIs from within Silverlight
