A powerful framework that allows creating user-defined functions for Mathcad 15 and Mathcad Prime using any .NET language (C#, VB.NET, F#, C++/CLI). This package provides a simple, attribute-based API that hides the complexity of the underlying C++/CLI host. Developers can write clean, strongly-typed functions by inheriting from a generic base class, focusing purely on their logic without boilerplate code.
