E.g I dont want to invoke `New-AzADGroup` just to be able to see what properties it will give me so I can use that in my script. Previously I've relied on IntelliSens in my editor, but it often fails, so I sought out to find a more manual solution (who would have thought..). Some modules provide information in their help about what type a particular cmdlet returns. We can use this to get information about what that type contains. If we look at the `Get-AzADGroup` cmdlet as an example. When we run `Get-Help Get-AzADGroup -Full` we can see under the "OUTPUT" section that it returns a `Microsoft.Azure.Commands.ActiveDirectory.PSADGroup` type. To inspect that type we can do the following. ```powershell PS > Get-Help Get-AzADGroup -Full ... OUTPUTS Microsoft.Azure.Commands.ActiveDirectory.PSADGroup ... PS > [Microsoft.Azure.Commands.ActiveDirectory.PSADGroup]::new() | gm TypeName: Microsoft.Azure.Commands.ActiveDirectory.PSADGroup Name MemberType Definition ---- ---------- ---------- Equals Method bool Equals(System.Object obj) GetHashCode Method int GetHashCode() GetType Method type GetType() ToString Method string ToString() AdditionalProperties Property System.Collections.Generic.IDictionary[string,System.Object] AdditionalProperties {get;set;} DeletionTimestamp Property System.Nullable[datetime] DeletionTimestamp {get;set;} Description Property string Description {get;set;} DisplayName Property string DisplayName {get;set;} Id Property string Id {get;set;} MailEnabled Property System.Nullable[bool] MailEnabled {get;set;} MailNickname Property string MailNickname {get;set;} ObjectType Property string ObjectType {get;} SecurityEnabled Property System.Nullable[bool] SecurityEnabled {get;set;} Type Property string Type {get;set;} ``` Here we can see what methods and properties we will get if we run `Get-AzADGroup`. Another solution is to call either the `GetMembers()`, `GetProperties()` or `GetMethods()` on the type which will give you detailed information about each member. It's a little verbose to be frank.. So I prefer the first method. ```powershell PS > [Microsoft.Azure.Commands.ActiveDirectory.PSADGroup].GetProperties() MemberType : Property Name : SecurityEnabled DeclaringType :
