Game.Exit method deprecated?

I was working on a Monogame Windows Application project in a single project solution when I decided I wanted to split the project into two separate projects; the actual game and the framework. Prior to me splitting the project into two projects, the Game.Exit method was working fine.

I made two separate projects, one a Monogame Windows Application project (the game itself) and one class library project with the necessary references to Monogame. The way I have my program structured, nothing is actually in the Game object (the one that derives from Monogame.Framework.Game), so I decided to put it in the framework as well. As soon as I put it in the framework project, it gave me an error saying the Game.Exit method has been deprecated.

I assume it has to do with the fact that I made the project a class library project as opposed to a Monogame Windows Application project, and I must be missing a reference somewhere or something like that. What can I do to fix this?
