VS2017 System.Messaging Does Not Exist in Namespace 'System'

In VS2017 C#, I declared using System.Messaging; because I wanted to use the message queue.
Namespace name 'Messaging' does not exist in namespace 'System'.
I've looked into various things, but I don't know.Also, the development is .NET Core, but it is also a console app
I get the same error.If you know how to solve this problem, please let me know.
