coeWindows-shared.dll must be built from the "coeWindows-shared" project in the NGSRI_TE_Common_SRNSTE72374 repo https://tfs.rms.ray.com/TE/NGSRI_TE/_git/NGSRI_TE_Common_SRNSTE72374 Branch: Dev Commit: 748d125cceab2fb7988876b425313b48f83fe04f COE version: v04.09.00.56 Had to fix a bug in "coeWindows-shared" code where it doesn't process the flag TCP_SELECT_VALUE which determine whether COE messaging goes through TCP or UDP in TCP mode. So it always uses UDP mode for COE messaging no matter what we set for TCP_SELECT_VALUE. Need Windows SDK Version 10.0.22621.0 in order to build This DLL must be built in release mode. If need to debug, rebuild the project in debug mode and replace this DLL with it. Only use debug DLL for debugging only. Otherwise, need to use the release DLL in order to process COE messages as fast as possible.
