What is the underlying framework for powershell

What is the underlying framework for powershell ?

I was told it is .NET, but what does that mean? or is WMI as well?

.NET is the framework.  It is developed using Microsoft's Visual Studio which includes the compilers for the different version including C++, VB.NET, and C#.NET.  Below are two links to tell you about .NET Framework.

No, I don't think so.  I think the WMI API is accessible from Powershell but COM API for WMI is written in C++ and not the .NET version.  More info here:  http://msdn.microsoft.com/en-us/library/aa389276%28v=vs.85%29.aspx

When you install PowerShell, you actually install the "Windows Management Framework" which includes updates to WMI/CIM and WS-Man as well as PowerShell itself.  Look at the $PSVersionTable variable for an indication of the bits.

PowerShell itself runs on .NET v2 or v4 depending on which version of PowerShell you are using,  It can make extensive use of WMI and especially its newer more standards-compliant version CIM because that is what a lot of management (and a lot of new Cmdlets) is built on.  It can also access COM stuff too.

The question is: does it matter?
No. PowerShell provides access to everything having a (.NET) interface. This included COM, WMI, and other stuff added by 3rd-party modules. You can even compile C#, C++-NET, VBScript, ... within PowerShell.
