Version Used:
Visual Studio 2022 v17.12.3

Steps to Reproduce:

1. Compile a project with a extension methods file.

Diagnostic Id:
IDE0130: Namespace "..." does not match folder structure, expected "..."

Expected Behavior:
Do not raise this issue, because all the extension method file have the namespace of the original file and this is a false positive. When a file contains methods with parameters that use the reserved word "this" the rule IDE0130 does not be reported.

Actual Behavior:
A issue of the rule IDE0130 is reported in each extension methods file.
