内容类型开发的声明性方法与程序化方法？

Question

For custom development of Content Types, which approach should be followed, Declarative Approach (via element.xml) vs Programmatic Approach (via code)? What are the pros and cons of each approach?

Answer 1

Declarative approach is preferred. However, the major disadvantage of declarative approach is that there is no standard way of upgrading the content types. Up gradation is normally done in this case by writing the feature receiver which makes the necessary corrections through WSS API.

Answer 2

I think you should use code.
