Using the PowerShell .NET API

There are a number cases where it's desirable to call PowerShell from another .NET language, particularly from C#. The two main classes of scenario here are:

Running PowerShell code or reusing PowerShell commands from a cmdlet or module.
Using PowerShell from a standalone .NET application, usually by hosting a fresh instance of PowerShell

Both use cases have a largely similar usage pattern,

Emulating Raspberry Pi 4 with Qemu

Just a quick update before we dive in: what we're actually doing here is running Raspberry Pi OS (64-bit) on a QEMU virtual ARM setup. This isn't full-blown hardware emulation of the Raspberry Pi 4, but more about creating a virtual environment for the OS. It doesn't mimic all the specific hardware features of the Pi 4, but it's pretty useful and great for general testing. I turned to this solution mainly to extract a modified sysroot from the Raspberry Pi OS, something not readily available in other resources. For those looking into detailed emulation of the actual Raspberry Pi 4's hardware in QEMU, check out this link for the latest updates: https://gitlab.com/qemu-project/qemu/-/issues/1208.

Hope it helps! :D

Shortcomings: No GUI yet, only console.

	Function Optimize-PSReadLineHistory {
	<#
	.SYNOPSIS
	Optimize the PSReadline history file
	.DESCRIPTION
	The PSReadline module can maintain a persistent command-line history. However, there are no provisions for managing the file. When the file gets very large, performance starting PowerShell can be affected. This command will trim the history file to a specified length as well as removing any duplicate entries.
