How is the SharePoint Online/Exchange Online/Lync Online platform different from the SharePoint 2010/Exchange 2010/Lync Server 2010 platform?

 In order to answer those questions and help you build solutions for the cloud with Office 365...

 The Office 365 Developer Training Course on MSDN - this training course includes 7 modules with over 10 hours of video and 17 hands-on-labs to help you get started building cloud based communication and collaboration solutions for Office 365, including:

Developing in the Cloud with Office 365

Office 365 provides a communication and collaboration service in the cloud that
you can leverage to build custom solutions for SharePoint Online, Exchange
Online and Lync Online. In this session, you'll learn about this new cloud
service and the breadth of solutions that can be developed using the same
skills, tools and SDKs you use today when building on-premises solutions.

 

Developing for SharePoint Online with Sandbox Solutions

Sandboxed Solutions are the development paradigm for SharePoint Online. In this
session, you'll learn about sandboxed solutions including how to develop, debug
and deploy solutions. You'll also learn the breadth of solutions that can be
developed in the sandbox and strategies for developing common scenarios that are
not enabled in the sandbox.

 

Building Workflow Solutions for SharePoint Online

Building Workflow solutions for SharePoint Online allows you to automate
collaboration-centric business processes and surface them to your users via
SharePoint Online. In this session, you'll learn the differences between
declarative and code-based workflows, design a workflow using Visio 2010,
implement that workflow in SharePoint Designer 2010 and customize the workflow
using Visual Studio 2010 and custom actions.

 

Developing SharePoint Online Solutions with the Client Object Model

The SharePoint Client Object Model provides libraries for programmatically
accessing SharePoint Online via Silverlight and JavaScript. In this session,
we'll go deep into the Client Object Model and show you how to develop solutions
using both Silverlight and JavaScript.

 

Leveraging Excel and Access Services in SharePoint Online

Excel and Access Services provide powerful features for building SharePoint
Online solutions. In this session, you'll get an inside look at both Excel and
Access services and how each can be accessed programmatically when building
SharePoint Online solutions.

Developing Communication Solutions for Lync Online

In this session, you learn how to integrate Lync features into your WPF and
Silverlight clients much in the same way that Office and SharePoint do,
including presence, contact lists and click-to-communicate features. You will
also learn how to extend Lync communications to include data and features from
your client applications much in the same way that Outlook 2010 does with the
"IM" and "Call" features within an email.

 

Developing Messaging Solutions for Exchange Online

In this session, you'll learn how to integrate Exchange Online mailbox data such
as mail, calendar and task items as well as Exchange Online services such as the
free-busy service into your applications using an easy to discover and easy to
use managed API.
