The Dynamics 365 CE SDK is dead, long live the new Developer Guide

From Dynamics 365 9.0 onwards, the SDK (Software Development Kit) is not available as a single SDK monolithic download – but it has been split up in different parts:

• Developer Guide for Dynamics 365 Customer Engagement  (still possible to export as PDF) – definitely take a look at  Xrm.WebApi (Client API reference)

• Dynamics 365 assemblies and some tools (e.g. solutionpackager, package deployer and plug-in registration tools) are now all available from NUGET – check out Microsoft.CrmSdk.CoreAssemblies on Nuget

• The Dynamics 365 Entity Reference is also available  (and updated) online
