Is there any plan to support .NET version Epcis v4

[superliujian]

Hi, I know there is a C++ and Java implement of EPICS v4, and even python interface, so I'm wondering if there is any plan to have .NET implement?

All the languages you have listed have very valid use cases. Java bindings are primarily used within CSStudio and image plugins for imagej etc. C++ and Python are primarily used in scientific applications and v4 IOCs. What's your use case for a .NET implementation?
PS: I would recommend you to use the mailing lists (e.g. techtalk) instead of github for these sorts of questions. We reserve this space for issues and people tend to be more responsive in mailing lists
