Windows PowerShell Activity Generator Sample

This sample shows how to use the Windows PowerShell Activity Generation API to generate the source code for an activity that wraps a Windows PowerShell command from C# code. The sample then and then compiles the source code into an activity dll.

The sample uses the System.Management.Automation.PowerShell API to get the definition of a command before calling the activity generation API. You can also accomplish this by calling the activity generator API from PowerShell directly, using the output of Get-Command as the command definition.

After you have generated the source code for an activity, compile it into a DLL and then reference that DLL from your Windows Workflow project.

The sample contains the New-PSActivity.ps1 script that can be used to generate the source code for one or more activities and to compile the source into a single activity dll.

Build the sample

  1. Start Microsoft Visual Studio and select File > Open > Project/Solution.

  2. Go to the directory named for the sample, and double-click the Visual Studio Solution (.sln) file.

  3. Make sure the project references the System.Management.Automation.dll assembly.

  4. Press F7 or use Build > Build Solution to build the sample.

    The library will be built in the default \bin or \bin\Debug directory.

Run the sample

Running the sample

  1. Start PowerShell and run the ActivityGenerator.exe program.
  2. If you wish to generate activities for a specific module, supply the module name as the first command-line parameter.

Generating the Source Code and Activity DLL

  1. Start PowerShell.
  2. Run the following command: .\New-PSActivity.ps1 -Namespace ActivityGenerator.Test -ModulePath .\Math.cdxml -OutputPath .\ -AssemblyName ActivityGenerator.Test.Activities.dll -verbose
  3. Reference ActivityGenerator.Test.Activities.dll DLL from your Windows Workflow project and create a workflow.
