Build Custom Windows PowerShell Desired State Configuration Resources

Applies To: Windows PowerShell 4.0, Windows PowerShell 5.0

Windows PowerShell Desired State Configuration (DSC) has built-in resources that you can use to configure your environment. (For more information, see Built-In Windows PowerShell Desired State Configuration Resources.) This topic provides an overview of developing resources and links to topics with specific information and examples.

DSC resource components

A DSC resource is a Windows PowerShell module. The module contains both the schema (the definition of the configurable properties) and the implementation (the code that does the actual work specified by a configuration) for the resource. A DSC resource schema can be defined in a MOF file, and the implementation is performed by a script module. Beginning with the support of PowerShell classes in version 5, the schema and implementation can both be defined in a class. The following topics describe in more detail how to create DSC resources.

• Writing a custom DSC resource with MOF
• Implementing a DSC resource in C#
• Writing a custom DSC resource with PowerShell classes
• Composite resources: Using a DSC configuration as a resource
• Using the Resource Designer tool
