Error ambiguous reference with Json

I am using both prime31 and minijson in a C# script
I am getting errors

error CS0104: Json' is an ambiguous reference between Prime31.Json’ and `MiniJSON.Json’

error CS0103: The name `Json’ does not exist in the current context

How can i escape fronm this?

Did you try qualifying the Json you are using in the context?

MiniJSON.Json.DoSomething() instead of Json.DoSomething()

Its the same thing as if you are using System; then try using Random, since UnityEngine has a definition for Random as does System
