# F55 / Path A — DCOM-managed callback sink.
# `windows-com` enables `dcom_sink.rs` which implements
# `INmxSvcCallback` as a real COM class via `windows-rs` `#[implement]`.
# The marshalled OBJREF passes NmxSvc's SCM-side OXID resolution
# where the hand-rolled `exporter.rs` approach fails. Default build
# stays slim — the windows crate is only pulled in when the consumer
# enables `windows-com`. Propagates through to
# `mxaccess-rpc/windows-com` so the OBJREF marshaller is available.

# windows-rs's `#[interface]` and `#[implement]` macros expand to
# absolute `::windows_core::*` paths, so the consumer must depend on
# `windows-core` directly (the `windows` crate's re-export at
# `windows::core` doesn't satisfy the macro's path resolution).
# Pin to the same 0.62 line as the `windows` dep above so the
# `IUnknown` / `IUnknown_Vtbl` types resolve to the same crate
# version that `mxaccess-rpc::com_objref_provider::IUnknownHolder`
# wraps — version skew between the two would surface as "expected
# IUnknown, found IUnknown" type errors at the
# `IUnknownHolder::from_iunknown` boundary.
