Prompting Github Copilot Coding With Fresh Context

Using Github Copilot, in either VSCode and Visual Studio, I have found that the context of previous questions and responses seem to pollute subsequent answers and the quality of answers seems to drop. I want to ask the AI a question with a fresh context and give an honest and detailed code review but it misses obvious errors in several cases.

The context engine seems to bind to the current project path as a key to access context information and there does not seem to be a way to have it ignore previous context. I tried starting with ignoring previous context but that did not work.

What is the idiomatic way to ask questions to Copilot for a project using a fresh context?
