compiler construction - using c# like script in runtime -

I want to learn that there is no library for writing C # scripts. Let me describe you in more detail, for example, I have an application when I run it, a C # editor will be opened, the end user will write some C # code and when click, this code should be evaluated and the domain After running, my run C # code should be interpreted as explained. This is a brief description of my mind ... I have applied a small app which says what I describe, I understand that it (codedom) Dislike and generally disappointed; However, it works fine for ordinary scenarios.
