====== gRPC Support for LV ======

NI shares a repo on Github which contains necessary C++ code and support VIs to implement a gRPC server and client in LabVIEW. You can either use the service as defined to implement a generic server via gRPC or use the implementation as a pattern to implement a gRPC service of your design. The project supports Windows, Linux, and Linux RT.
