I have made a ContentPipeline for your SpriteFactory.

Hello, I have made a custom pipeline for your sprite factory. You may have to change the namespace BUT it is working. For this to work make sure to use https://www.nuget.org/packages/MonoGame.Framework.Content.Pipeline/ that uses monogame 3.8.0.1641.

IF you are using .net core, make use to make a class library of netstandard 2.0 and had these files inside it. Make sure to add your dll AND newtonsoft json dll to the content pipeline app. Reason json.net because it converts your json to spritefactory.

Important Info: you will have to edit SpriteFactoryWriter "GetRuntimeReader" and "GetRuntimeType" to your own namespace.

here are the files:
SpriteFactoryPipeline.zip

Damn it. Was looking for something with 3.8.

Hey @shmellyorc, why not make a pull request? It will be much simpler to review and follow some conversations regarding your implementation. That's a preferred OSS way, not sharing zip files.
