Sample: Query connection roles by entity type code (early bound)
Applies To: Dynamics CRM 2015
This sample code is for Microsoft Dynamics CRM 2015 and Microsoft Dynamics CRM Online 2015 Update. Download the Microsoft Dynamics CRM SDK package. It can be found in the following location in the download package:
SampleCode\CS\BusinessDataModel\BusinessManagement\QueryConnectionRolesByEntityTypeCode.cs
Requirements

Demonstrates
This sample shows how to use a query to find a connection role for an account entity by specifying an entity type code.
Example
using System;
using System.ServiceModel;
// These namespaces are found in the Microsoft.Xrm.Sdk.dll assembly
// found in the SDK\bin folder.
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Client;
using Microsoft.Xrm.Sdk.Query;

/// for accounts at this point, not for all. Subsequently the link to the account
/// entity is removed and it is shown that the role is now applicable to all
