Should adding some partial function in StaticConstructorGenerator? Or other implementations

[noliar]

Currently, In Avalonia, this library cannot generate all the code related to DependencyProperty and RoutedEvent, etc. like AddClassHandler, OverrideDefaultValue. (Of course, AddClassHandlercan change it to AddHanlder):

And a type can only have one static constructor.

If we manualy add both static constructor and OnXXChanged partial method, we will get error CS0111

Should we add new partial method in StaticConstructorGenerator? like this:

static partial void StartOfStaticConstructor();  // or other name
static partial void EndOfStaticConstructor(); // or other name

and adding manual code in partial method.

Or adding new attribute like [PostStaticConstructorAttribute] to a static method?

Or other implementations?

I think partial methods is the best solution.
In an ideal situation, I would of course do without using static constructors at all, now this is some kind of workaround, but my experience in Avalonia does not allow me to see other possible ways
