Question

If I have

abstract class Base<TSub>
{
    protected static List<TSub> MyStaticList;
}

class DerivedA : Base<DerivedA>
{
}

class DerivedB : Base<DerivedB>
{

}

I get two independent MyStaticList variables, one for each base class.
If instead the base looked like this

class Base<TSub>
{
    protected static List<string> MyStaticList;
}

i.e., the template parameter was nowhere used, am I guaranteed to still get two independent MyStaticList variables?

(I need this for the availableValues() method of a customized Enum-like class hierarchy.)

A static variable in a generic class declaration is shared amongst all
instances of the same closed constructed type (§26.5.2), but is not
shared amongst instances of different closed constructed types. These
rules apply regardless of whether the type of the static variable
involves any type parameters or not.

EDIT
A very similar question was asked before Generic List and static variable behaviour in c#

You’ll have to go with a fully static construct to use inside of your generic classes. Maybe something like…

protected static List<TSub> MyStaticList = BaseUtil.MyStaticList
