"It should be written as if ({'yourObject'}?.{'Property'} != null)"

Rule description

The ?. operator lets you access members and elements only when the receiver is not-null, returning null result otherwise. It is exactly what we except when checking an object is null or not like the samples below, while ?. is more meaningful and readable.

Example

if (myCookie != null && myCookie.Value != null)
{
    ...
}

should be 🡻

if (myCookie?.Value != null)
{
    ...
}
