get_instantiation_options

Answer 'how do I construct this type?' in one call — accessible constructors, static factory methods declared anywhere in the solution, and DI registrations. Constructors report every parameter's type and name, declared accessibility, whether the constructor is compiler-supplied (isImplicit — a struct or a class with no declared constructor still has a usable parameterless one), and whether it is obsolete. Factories are static members returning the type, including ones declared on a DIFFERENT type such as WidgetFactory.Create(), with Task<T>/ValueTask<T> unwrapped and flagged isAsync. Instance builder methods are excluded because the builder itself would need constructing. Pass fromProject to get accessible computed for that project, which honours InternalsVisibleTo — this is how you find out whether your test project can reach an internal constructor. Without it, accessible is null, meaning NOT COMPUTED — which is not the same as false, so do not read a null as 'you cannot call this'. requiredMembers lists members that must be set in an object initializer. diRegistrations shows where the type is registered in a container — a registered type is usually meant to be resolved rather than constructed by hand. For interfaces, abstract classes and static classes, instantiable is false and note explains why; use find_implementations to find concrete types.
