Is there a Lint Rule or Some way to indicate something implements IDisposable

[chris-clark-serverless]

public class MailMessage : IDisposable

It's not always immediately clear that something implements IDisposable. This can cause memory issues, and I would like for a way to detect if an instance of a class is made without a using on something that implements IDisposable

However, this rule is very unreliable. It doesn't properly track ownership transferring (storing values to fields), which is a very complex problem.

Moreover, fail to call Dispose on usual objects do not cause memory issue, because there is finalizer. It's usually a performance issue instead.
