Sharepoint 2013 - CSOM and Powershell

Hi

Is there any definative guide on the differences between what can be done in C# for CSOM and Powershell with CSOM ?

I am finding it difficult to adapt some C# samples to powershell as powershell seems to be a subset of C# (i.e. some properties and methods are missing)

e.g.  list["get this one"] works in C# not Powershell

Many thanks
