MarkdownRender is a hybrid solution, it is both a class library which can be used from .NET Framework projects, and a Windows PowerShell binary module - hidden inside a script module, meant to provide the ConvertFrom-Markdown function inside Windows PowerShell.
This is a module for Windows PowerShell 5.1 meant to introduce support for ConvertFrom-Markdown which has been introduced with PowerShell 6.1.
ConvertFrom-Markdown does one thing, it converts Markdown to HTML, and returns a MarkdownInfo object with a .html property.
# to access the HTML content use the .html property
$html = (ConvertFrom-Markdown -Path "C:\Temp\test.md").html
