Building a custom DSC Resource using C #

Prepare Prerequisites

1. 1. VisualStudio recommended 2012 or higher

2. 2. PowerShell4.0

3. 3. MOF file

Overview

2. 1. when building a DSC resource using C #, you also need the MOF (the DSC resource schema file) to generate the file we can build using the Xdscresource tool published on TechNet

4. 2. The following three cmdlets are also required when building DSC resources using C # Get-targetresource,set-targetresource,test-targetresource

6. 3. Get-targetresource used to get the current resource state, this command must return a hash dictionary that is System.Collections.Hashtable

8. 4. Test-targetresource used to detect whether the current resource state is consistent with user input, this command must return a Boolean type that is System.Boolean

10. 5. Set-targetresource used to complete the user input state, this command does not need to return

Create a MOF schema file

In this example, we will implement the file resource resource name of the system Xfiles

The following is the schema file (file name XFiles.schema.mof)

[Classversion ("1.0.0.0"), FriendlyName ("Xfiles")]

Classxfiles:omi_baseresource

{

[Key] String ensure;

[Required] String Name;

[Required] String Path;

};

Only three parameter ensure,name,path are defined in this architecture and are required

Implementing the Schema

Open vs Create C # class library project

Simultaneous renaming of the assembly name is the DSC resource name, which is Xfiles

Adding a reference to a System.Management.Automation.dll

Path to (. NET version different file path location may vary slightly)

C:\Windows\Microsoft.NET\assembly\GAC_MSIL\System.Management.Automation\v4.0_3.0.0.0__31bf3856ad364e35\ System.Management.Automation.dll

Implement Get-targetresource

Implement Test-targetresource Note that Test-targetresource requires a Boolean type to be returned

However, because the rewrite Processrecord () method must require void so that when we judge the state of the resource

Use the WriteObject () method to return a Boolean type

Implement Set-targetresource

Then build the solution

Place the generated XFiles.DLL with the XFiles.schema.mof

C:\Windows\System32\WindowsPowerShell\v1.0\Modules\PSDesiredStateConfiguration\DSCResources\xFiles under

Such as

Then write the DSC configuration file

Configuration AAA

{

Node LocalHost

{

Xfiles BBB

{

Name = "1.txt"

Path = "C:\2\"

ensure = "absent"

}

}

}

Test

Test resource Status separately

Application configuration (all configuration requirements are not currently satisfied)

Application configuration (partial configuration status satisfies the C:\2 directory in this example)

Undo configuration (All configurations require that all required undo configuration currently exists)

Undo configuration (Partial configuration state satisfied that C:\2\1.txt does not exist)
