AutoCAD_Dev_with_Csharp

Preface

Apparently, we can develop APIs with LISP and .NET . Though I have been checking some articles mentioning the pros and cons for using one another, it is still unclear to me, which scenario suit for which development method. I think I might realize the answer of this question along my development journey. Few weeks ago, I learned some basic LISP, but the materials that I checked wasn’t completed. LISP is the second oldest programming language that still exist, which make the programmer like me a bit hard to catch up easily. Since I spent more time developing in C#, it won’t hurt if I learn a bit how to develop AutoCAD API in .NET framework.
