Using NuGet in Visual Studio, you will need to retrieve the usual Dynamics 365 assemblies. Alternatively, you can try to source the DLL manually from the SDK. Refer to the Creating your first plugin recipe in Chapter 4, Server-Side Extensions for details.

Your plugin requires a register service endpoint in your Dynamics 365 instance. We can reuse the endpoint created in the previous recipe. You will need the GUID of that endpoint. The easiest way to get the GUID is to run the following query in a Chrome browser:

<YourDynamics365OrganizationURI>/api/data/v8.2/serviceendpoints?$select=name,serviceendpointid

Finally, you will need the usual Dynamics 365 security role of System Customizer or higher in order to register the plugin.
