The Microsoft Dynamics CRM 4.0 Software Development Kit (SDK) is now ready for download on MSDN. The SDK is for developers, system customizers, and report writers.

It contains all new information about creating plug-ins, working with custom workflow activities, using the new Web services, using new data management features, and much more. It also contains information for developers writing server side code, custom business logic, integration modules, workflow assemblies, and more. It provides an architectural overview of Microsoft Dynamics CRM, the entity model, security model, and Web services. Sample code and walkthroughs guide you through the new features.

The SDK also contains information for developers customizing the Web client or Microsoft Dynamics CRM for Microsoft Office Outlook, including scripting, integration of custom Web pages, sample code, and a detailed user interface style guide.

This release contains lots of new sample code, walkthroughs and general information about the new features. It will be updated once a month for the next 3-4 months while we fill in some of the cracks and then on a quarterly basis.

Feedback is welcome!
