## What it is
A C# command-line tool that generates JScript (or VBScript/VBA/scriptlet) files which bootstrap and load a .NET assembly entirely from memory via Windows Script Host. It is commonly used in security research and red-team tooling to execute .NET payloads without writing assemblies to disk.

## Use cases
- generate a jscript file that loads a .net assembly from memory
- create scriptlets for regsvr32 execution
- embed a .net payload in an office macro vba file
- run dotnet code without dropping files to disk
- convert a .net assembly into a wscript-executable script

## When to choose
- you need fileless execution of a .NET assembly via Windows Script Host
- you are building red-team or security-research tooling for Windows
- you need scriptlet, regsvr32, VBA, or VBScript output formats

## When to avoid
- you need a modern, actively maintained tool
- you target .NET Core/.NET 5+ rather than .NET Framework 2/3.5/4
- you need cross-platform or non-Windows execution

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: security, cli, developer-tools
- domain: security, penetration-testing, windows, developer-tools
- platform: windows, cli, dotnet
- tags: jscript, dotnet, offensive-security, red-team, scriptlet, wscript, vba, vbscript, assembly-loader
