Sample: Create a workflow in code

 

Applies To: Dynamics CRM 2013

This sample code is for Microsoft Dynamics CRM 2013 and Microsoft Dynamics CRM Online. 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

SampleCode\VB\Process\Workflows\CreateAWorkflow.vb

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 CRM 2011 because custom XAML workflows are not supported in Microsoft Dynamics CRM Online.
