To develop Microsoft Dynamics CRM workflow activities, use the following tools and components:
- Microsoft Visual Studio 2005
- Windows Workflow Foundation
- Microsoft Dynamics CRM 4.0
- A valid user account on Microsoft Dynamics CRM 4.0
Required Assemblies
The following assemblies must be added to your project. They can be found in the SDK\Bin folder.
Microsoft.Crm.Sdk.dll
Microsoft.Crm.SdkTypeProxy.dll
For more information, see About the Assemblies.
Registering Custom Workflow Activities
After your custom workflow activity has been compiled, you have to register this assembly as a plug-in. Your workflow will then appear in the workflow form in the Microsoft Dynamics CRM Web application.
This SDK includes a registration tool to improve developer productivity. For more information about the tool sample code, see Sample Code. For a walkthrough, see Build the Plug-in Registration Tool and Registering a Plug-in using the Plug-in Developer Tool.
