public sealed class Shader : Object

Remarks

Most of the advanced rendering is controlled via Material class. Shader class is mostly used just to check whether a shader can run on the user's hardware (Shader.isSupported property), setting up global shader properties and keywords, and finding shaders by name (Shader.Find method).
Additional Resources: Material class, Materials, ShaderLab documentation.
