get_public_api_surface

Enumerate every public and protected type and member declared in production projects of the active solution. Returns a deterministically-sorted (name ASC) flat list of API entries (kind, fully-qualified name, accessibility, project, file, line) plus per-kind/per-project/per-accessibility summary buckets. Skips test projects, generated code, compiler-generated members, internal symbols, and protected members on sealed types (unreachable). Inherited members are not repeated under derived types — only declared members appear.
