"Use foo is Bar as negative logic is taxing on the brain."

Rule description

Human brain can understand positive expressions and statements faster than negative ones. To improve code readability it is better to use if(expression is type) rather than if(expression as type ! = null).

Example

if(foo as string != null)
{
    ...
}

should be 🡻

if(foo is string)
{
    ...
}
