are attributes inherited

[Dan Holmes]

Say i have:

[Serializable]
public class A
{

}

public class B : A
{
}

does B need the serializable attribute as well?

Attributes are inherited.

But SerializableAttribute has Inherited=false attribute and cannot be
inherited:

[ComVisible(true), AttributeUsage(AttributeTargets.Delegate |
AttributeTargets.Enum | AttributeTargets.Struct |
AttributeTargets.Class, Inherited=false)]
public sealed class SerializableAttribute : Attribute
{
...
}

So B needs this one also.

In this case yes. See "AttributeUsageAttribute.Inherited".

Well, in this particular case yes, you do. However, the attribute
itself defines if it will be inherited, so you'll have to check the
documentation.
