Unary is expression can be simplified CS-R1094
Anti-pattern
Critical
Autofix The is operator allows you to check if a variable belongs to a specific type. The same operator can be chained with not to check for the inverse. It is therefore recommended that you simplify the is expression to improve readability.
Bad Practice
if (!(foo is Foo))
{
// ...
}
Recommended
if (foo is not Foo)
{
// ...
}
