Sample: Create a workflow in code
Applies To: Dynamics 365 (online), Dynamics 365 (on-premises), Dynamics CRM 2016, Dynamics CRM Online
This sample code is for Microsoft Dynamics 365 (online & on-premises). Download the Microsoft Dynamics CRM SDK package. It can be found in the following location in the download package:
SampleCode\CS\Process\Workflows\CreateAWorkflow.cs
Requirements
You must enable support for custom XAML workflows on your on-premises server. For more information, see Enable or disable XAML workflows. For more information about the requirements for running the sample code provided in this SDK, see Use the sample and helper code.
Demonstrates
The following sample shows how to programmatically create an asynchronous workflow in code instead of using a workflow editor or designer. This sample works only with an on-premises deployment of Microsoft Dynamics 365 because custom XAML workflows are not supported in Microsoft Dynamics 365 (online).
Example
using System;
using System.ServiceModel;
// These namespaces are found in the Microsoft.Xrm.Sdk.dll assembly
// located in the SDK\bin folder of the SDK download.
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Client;
// These namespaces are found in the Microsoft.Crm.Sdk.Proxy.dll assembly
// located in the SDK\bin folder of the SDK download.
