The IDiscoveryServiceWeb service is used to determine the organizations that a user is a member of, and the endpoint address URL to access the IOrganizationServiceWeb service for each of those organizations. This discovery service is necessary because Microsoft Dynamics 365is a multi-tenant environment—a single Microsoft Dynamics 365server can host multiple business organizations. By using the discovery Web service, your application can determine the endpoint address URL to access the target organization’s business data.

For Microsoft Dynamics 365 (online & on-premises)installations, server and organization allocation may change as part of datacenter management and load balancing. Therefore, the IDiscoveryServiceWeb service provides a way to discover which Microsoft Dynamics 365server is serving your organization at a given time.

The following table lists the Web service URLs for the worldwide Microsoft Dynamics 365 (online)data centers.

For an on-premises installation, the web service URL has the following form:

http[s]://<hostname[:port]>/XRMServices/2011/Discovery.svc

Consult the Developer Resourcespage in the Microsoft Dynamics 365Web application for the correct URL of your installation.

To use the IDiscoveryServiceWeb service, add a reference to the Microsoft.Xrm.Sdk.dllassembly to your Microsoft Visual Studioproject, and then add a usingor importsstatement to access the Microsoft.Xrm.Sdk.Discoverynamespace.
