How to disable warnings in only one project?

Question

I have a legacy project in my solution without comments and many warnings. I want to not see warnings about this specific project but I want to see warnings of the other pro

Answer 1

Open the Properties of the project and go to the Build page.
Here you will find the Error & Warnings input box
Put the warning number to hide in the input box without the first two letters
If you have more than one warning separate them with colon or semi-colon

(Sorry if labels are not precise, I'm translating from another language VS)
