# What is Interop Services?

The common language runtime(CLR) provides two mechanisms for interoperating with unmanaged code: \
\
• Platform invoke, which enables managed code to call functions exported from an unmanaged library. \
• COM interop, which enables managed code to interact with COM objects through interfaces. \
\
Both platform invoke and COM interop use interop marshaling to accurately move method arguments between caller and callee and back, if required.\
