- How can I pass in a func with a generic type parameter?
You can certainly define generic delegates, after all, that's exactly what Func and Action are They are treated as generic definitions, just like generic interfaces and classes are However, you cannot use generic definitions in method signatures, only parameterized generic types Quite simply you cannot do what you are trying to achieve with a delegate alone

- Calling a static method on a generic type parameter
This answer cleverly "abuses" the somehow inconsistent rule, that you can, in your base class, create new objects of yet-unknown generic type, inheriting that base class - but you can't access the already-know static fields of that type (T SomeFileld) Great! Though is seems incompatible with static constructors in derived types (I get "null reference exception" on "private static readonly T
