I am trying to create a simple TFS vNext task, using Powershell to execute a Powershell script.
I could load the task, but after I trigger a release using the task, I get
##[error]System.Management.Automation.ParameterBindingException: A parameter cannot be found that matches parameter name 'PoolName'.
My task.json is as below.

}
And my Powershell script is here.

I have another simple task which does not take any parameter and it works perfectly fine.
Any pointers?
What am I missing?
If you are using the VSTS Build Task SDK you need to be using Powershell 3..
"execution": { "PowerShell3": { "target": "ManageIIS.ps1", } }
