Type EquivalenceType Equivalence
Interop Assemblies translate between managed code and COM
For each interface, struct, enum, delegate, and member, contains a
managed equivalent with marshalling data
Primary Interop Assemblies cause many
pain points…
However!However!
Go Away, PIA!Go Away, PIA!
1. Compilers embed the portions of the interop assemblies that the add-ins actually use
2. Runtime ensures the embedded definitions of these types are considered equivalent
