GUI over PowerShell Design Principles

Separation of business and presentation logic is key

> Enables “skinning” the same operations through many tools > Otherwise much time can be spent building one-off solutions > Enables partitioning of engineering work

Large surface area should not mean exposing everything to everyone

> Some customers may never need to or should never see <feature x>

> Even within the same customer, there are multiple personas (AD vs. Exchange admin)

> Different personas have different scopes of responsibility

Don’t expect users to figure it all out the first time or ever

> Make it simple> Make it consistent > Make it flexible > Err on the side of frequent failures, and then auto or easy

demo

What did we leverage?

> Command Consistency and Discovery> Verb-Noun

> Script Cmdlets> Easily construct composite commands

> Adaptive Type System> Default Display Property Set

> Simple PowerShell hosting API> Easy Data Binding

Remote UI, Focused actions and Script display

What did we leverage?

> Built-in Remoting> Adaptive Type System

> custom properties/methods> csv, xml, ado, etc

> Stateless execution (runspace pool)> PowerShell API (Script Display)

Delegation and Customized UI

Narayanan LakshmananDeveloperWindows Management

demo

PowerShell Delegated AdministrationRemoting execution connects to an endpoint

> PS> New-PSSession –ConfigurationName Inventory

Register endpoints with a Name, ACL, StartupScript

StartupScript can configure> LanguageMode: Full, Restricted, None> Commands available

Delegate by…> Registering Endpoints with different capabilities> Scripting different capabilities based upon incoming
