"Negative logical comparisons are taxing on the brain. Instead of "!object.Any()" use "object.None()"."

Rule description

Comparisons are more clear and meaningful while we don’t use negative syntax.

Example 1

if(!myObj.HasValue)
{
    ...
}

should be 🡻

if(myObj == null)
{
    ...
}

Example 2

if(!data.Any(d => d.ProductCode == 120))
{
    ...
}                    

should be 🡻

if(data.None(d => d.ProductCode == 120))
{
    ...
}
