PowerShell Workflow is a feature of PowerShell that enables you to write and run long-running, repeatable, and resilient workflows using PowerShell. Workflows are sets of instructions that can be run as a single unit, rather than running each instruction individually. They allow you to automate complex and long-running tasks, and they can be run on a schedule or on demand.  Desired State Configuration (DSC) is a declarative configuration management platform in PowerShell that enables you to manage your infrastructure and applications in a predictable and repeatable way. With DSC, you can define the desired configuration of your infrastructure and applications, and then use PowerShell to ensure that the actual configuration conforms to the desired state.  To work with Workflow and DSC in PowerShell, you will need to first install the necessary modules. To install the Workflow and DSC modules, you can use the following command:  Install-Module -Name PowerShellWorkflow, DSC-ResourceKit  Once the modules are installed, you can use PowerShell Workflow and DSC in your scripts by importing the necessary modules. For example, to import the Workflow and DSC modules, you can use the following commands:  Import-Module PowerShellWorkflow
Import-Module DSC-ResourceKit  You can then use the Workflow and DSC cmdlets to create and run workflows and to manage your infrastructure and applications. For example, to create a new DSC configuration, you can use the following command:  New-DSCConfiguration -Path C:\\MyConfiguration -Force  And to run a DSC configuration, you can use the following command:  Start-DSCConfiguration -Path C:\\MyConfiguration -Wait -Verbose  You can also use Workflow to create long-running and repeatable workflows. For example, to create a new Workflow, you can use the following command:  workflow MyWorkflow {
# Workflow code goes here
} And to run a Workflow, you can use the following command:  MyWorkflow
