PowerShell 7 • My Notes

This article will show you how to empower your Windows OS with modern PowerShell & other convenient tools.

PowerShell#

PowerShell is a cross-platform task automation solution made up of a command-line shell, a scripting language, and a configuration management framework. PowerShell runs on Windows, Linux, and macOS.

PowerShell 7#

Differences between PS 5 and PS 7#

Windows PowerShell 5.1 is built on top of the .NET Framework v4.5. With the release of PowerShell 6.0, PowerShell became an open source project built on .NET Core 2.0. PowerShell 7.0 is built on .NET Core 3.1. And, with the release of PowerShell 7.2, PowerShell will be built on .NET 6.0. Moving from the .NET Framework to .NET Core allowed PowerShell to become a cross-platform solution. PowerShell runs on Windows, macOS, and Linux.

There are few differences in the PowerShell language between Windows PowerShell and PowerShell. The differences are most notable in the availability and behavior of PowerShell cmdlets between Windows and non-Windows platforms and the changes that stem from the differences between the .NET Framework and .NET Core.
