The documentation contains information and resources for developers who create code-based extensions for Dynamics 365 (formerly known as Dynamics CRM).

The SDK includes an architectural overview of Dynamics 365, the entity model, security model, and web services. Sample code and walkthroughs are provided to guide you through the new features. It also contains information for developers who customize the web client or Dynamics 365 for Microsoft Office Outlook, including scripting, integration of custom webpages, and sample code.

In addition to the documentation, this download package includes the assemblies and tools needed for development, helper code for authentication, and Microsoft Visual Studio projects for the sample code found in the documentation.

You can also download the User Interface Integration (UII) solution framework, which includes a deployment guide, development guide, and API reference. UII uses Microsoft Dynamics 365 for the delivery of configuration data for the Integrated Agent Desktop. It includes development and runtime components. Applications built with UII can provide unified access to customer information across different systems, and can aggregate different modes of customer interactions or channels.

The UII download package also contains developer assets for Unified Service Desk 2.0, which includes a default Unified Service Desk 2.0 configuration data schema file, default style (theme), sample panel layout, developer guide, and sample code for the custom controls available in the sample applications. For more information about Unified Service Desk 2.0, see the Unified Service Desk 2.0 Developer Guide.
