As mentioned earlier, PowerShell is built on the .NET Framework. This implies that everything within PowerShell is object-based. This is a familiar concept for anyone who is already familiar with the .NET Framework or .NET programming languages such as C# or Visual Basic.
This object-based functionality is an important concept to remember if you want to dive deeper into PowerShell. PowerShell provides many features, and it can also use additional features provided by other .NET assemblies.
