What is the utility of the attribute GeneratedCodeAttribute in C #?

Question

I generated some of my C# code with an external tool. Each generated class has an attribute GeneratedCodeAttribute. Why is my generator creating this attribute?

Answer 1

This attribute was set because this code is generated by tool, not by human :) what is use of it you might ask? MSDN tells us:

The GeneratedCodeAttribute class can be used by code analysis tools to identify computer-generated code, and to provide an analysis based on the tool and the version of the tool that generated the code.

Answer 2

The first link is its documentation and the second link is a detailed description of what this is for, why code generators produce it, and how code analyzers consume it.

Does that answer your question?
