Get implementation of sharepoint powershell cmdlets

Question

How to find managed code SharePoint (whichever version) cmdlets implementations?

MSDN does not specify where and how cmdlets are implemented. There is only information how to use them. Is this done for some reason?

Answer 1

So I started digging…

Let’s for example take SharePoint 2013 15 Hive.

15 Hive folder structure explained: SharePoint 2013: The 15 Hive and other important directories

CMDLET Registration files location

15/Config/Powershell/Registration folder contains XML cmdlet registration files where for given assembly there are defined list of cmdlet definitions.

Sample XML

<ps:Cmdlet>
    <ps:VerbName>Uninstall-SPFeature</ps:VerbName>
    <ps:ClassName>Microsoft.SharePoint.PowerShell.SPCmdletUninstallFeature</ps:ClassName>
    <ps:HelpFile>Microsoft.SharePoint.PowerShell.dll-help.xml</ps:HelpFile>
</ps:Cmdlet>

SharePoint cmdlets are registered in WSSCmdlet.xml (there is a lot more) and their definition Assembly is:

Assembly Name="Microsoft.SharePoint.PowerShell, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c"

Assembly is located in GAC:

C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Microsoft.SharePoint.PowerShell

Manged C# Code

Using decompiler like ILSpy you can find exact class in DLL and get c# implementation of cmdlet.

For example

[SPCmdlet(RequireLocalFarmExist = true), Cmdlet("Get", "SPSiteUrl", SupportsShouldProcess = true)]
public sealed class SPCmdletGetSPSiteUrl : SPGetCmdletBase<SPSiteUrl>
{
    // implementation details irrelevant for question context
}
