PowerShell 7 Installer

How to Install and Update PowerShell 7

The PowerShell team just announced PowerShell 7. PowerShell 7 is built on .NET Core 3 and brings back many APIs required by modules built on .NET Framework so that they work with .NET Core runtime. While PowerShell Core 6 was focusing on bringing cross-platform compatibility, PowerShell 7 will focus on making it a viable replacement for Windows PowerShell 5.1 and bringing near parity with Windows PowerShell. Here is how you can install and update PowerShell 7 on Windows and Linux using a simple one-liner.
