C# Raytracer Code Debugging and Enhancement

I have a proof of concept code for a raytracer in C# which has some compilation errors that need to be fixed. I've already identified the specific parts of the code that are causing issues, so I need a programmer to solve these compilation errors and produce a working version of the code. The milestone for this project will be the generation of a bitmap image given sample geometry.

Ideal skills and experience:
- Proficiency in C# programming
- Experience with raytracing algorithms
- Debugging and problem-solving skills
- Familiarity with image processing in C#
- Ability to deliver quality work within a defined milestone
