Where is the "Invoke" member in System.Management.Automation.VerbsCommon?

I'm trying to create a cmdlet with the name Invoke-So开发者_运维知识库mething. But I cannot find the member "Invoke" to put in the attribute:

[Cmdlet(VerbsCommon.Invoke, "Something", SupportsShouldProcess = true)]
                    ^^^^^^

What am I missing?

I've found it: VerbsLifecycle.Invoke
