"Remove the unnecessary casting."

Rule description

You should not use explicit casting code such as (TypeX)someValue where someValue is already implicitly castable to TypeX. Unnecessary explicit casting is noise in code, and can even decrease performance.

Example1

void Foo(int foo)
{
    var bar = (int)foo;
}

should be 🡻

void Foo(int foo)
{
    var bar = foo;
}

Example2

var bar = (int)Foo();

public int Foo()
{
    ...
}

should be 🡻

var bar = Foo();

public int Foo()
{
    ...
}
