Get-ReferencedAssemblies.ps1

<# 
.SYNOPSIS
    This script takes an assembly file path as input and lists its referenced assemblies.
.DESCRIPTION
    The script loads a .NET assembly using the ReflectionOnlyLoadFrom method 
    and retrieves all the assemblies that the input assembly references.

.PARAMETER AssemblyPath
    The full path to the .NET assembly (.dll) whose references need to be inspected.

.EXAMPLE
    .\Get-AssemblyReferences.ps1 -AssemblyPath "C:\Path\To\YourAssembly.dll"
    This will output the list of assemblies that `YourAssembly.dll` references.

.NOTES
    The script works with .NET Framework assemblies and requires PowerShell to be run in an environment 
    where .NET Framework is available.
