Sample: Quick start for Microsoft Dynamics CRM

Applies To: CRM 2015 on-prem, CRM Online

The QuickStart sample is a Microsoft .NET Framework managed code sample that shows how to connect to the Microsoft Dynamics CRM 2011 and Microsoft Dynamics CRM Online web services by using the ServerConnection helper class and perform basic create, update, retrieve, and delete operations on an entity.

Requirements

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:

SDK\SampleCode\CS\QuickStart

Demonstrates

This sample authenticates the user with the Microsoft Dynamics CRM web services by using the ServerConnection helper class and methods. After obtaining a reference to the Organization web service, the sample performs basic create, update, retrieve, and delete operations on an account entity. The sample also handles common exceptions that can be thrown.

Example


using System;
using System.ServiceModel;
using System.IdentityModel.Tokens;
using System.ServiceModel.Security;

// These namespaces are found in the Microsoft.Xrm.Sdk.dll and 
// Microsoft.Crm.Sdk.Proxy.dll assemblies.
