.NET Core: Identify All Classes that Inherit from Generic Base Class

I would like to iterate all classes that derive from a generic base class. My problem is that I do not know how (if it is possible) to get the generic base class as a Type.

I can do:

Type myGeneric = typeof(MyGeneric<MyConcreteA,MyConcreteB>);

I cannot do:

Type myGeneric = typeof(MyGeneric<TMyA,TMyB>));

Is something like this possible?

foreach (Assembly asm in AppDomain.CurrentDomain.GetAssemblies())
{
    foreach (Type type in asm.GetTypes().Where(myType => myType.IsClass && !myType.IsAbstract))
    {
        if (type.IsSubclassOf(myGeneric))

Does this answer your question? [Get all types implementing specific open generic type](https://stackoverflow.com/questions/8645430/get-all-types-implementing-specific-open-generic-type) – Pavel Anikhouski Jun 06 '20 at 13:58
Thank you! I am hoping that this is the clue: Type t = typeof(IWhatever<>); which seems to compile for an interface but maybe not a concrete type. Maybe I need to refactor to an interface. – commodore73 Jun 06 '20 at 14:26
Actually, I can't seem to do typoof(IWhatever<>) either. So I am not sure whether this is an answer. – commodore73 Jun 06 '20 at 15:07
`typeof(x – Jeremy Lakeman Jul 24 '20 at 01:04
But implementing a non-generic interface is the simplest solution. – Jeremy Lakeman Jul 24 '20 at 01:07
Ah, just noticed that you have two generic parameters, you still need the comma in the parameter list `typeof(MyGeneric<,>)` – Jeremy Lakeman Jul 24 '20 at 01:09
