For previous versions of Microsoft Dynamics CRM and 365, developers were able to download an SDK containing information on writing server-side code, client-side scripts, custom business logic, integration modules, workflow assemblies, and plug-ins. However, with the latest version of Dynamics 365, the SDK is no more and these resources have now moved online.
With Microsoft’s continued commitment to having everything online, it makes sense that the SDK should become a part of this transition. Previous versions of the SDK, for CRM 4.0, CRM 2011, CRM 2013, CRM 2015 and Dynamics 365 Version 8 can still be downloaded, but Version 9 is solely online and can be found here. As with previous versions, the SDK includes guides on how to connect to, customise and extended Dynamics 365, along with code samples to help you get started.
As this documentation is now online, developers can be sure that they’re always referring to the latest version and will no longer have to download updates to their SDK. For those who prefer to keep a copy of this guide offline, Microsoft do provide a downloadable PDF option (available at the foot of the page), with all the content included, but this currently weighs in at over 13,000 pages.
