He said VS.NET, so perhaps he's referring to *unmanaged* C++. There is no way to load a .NET application sans the framework.
To answer the original poster's question, no, you cannot package it as an executable; there's nothing to execute! The application type exe/winexe in .NET has to have an entry point, not surprisingly named Main. No main, no entry point, no point of execution. Why not simply create a Win Forms/Console app that references the assembly you created and delegate as necessary?
