I can't add the mysql reference

I am running csharp_sample.exe. An attempt was made to add a mysql reference but it was not retrieved. Tell me how!

(develop setting)

  • Win10 64bit
  • Visual studio 2019
  • Intel realsense 435
  • Nuitrack Pro perpetual license

The following is [nuitrack_csharp_sample - References - (right mouse button)Add reference,] screen.

Where is assembly tab?

I created the project normally through Cmake, and it runs fine.

What is the problem?

Help me ㅜㅜ @olga.kuzminykh
