runtimeconfig.json schema

This defines the schema for .NET Core's runtimeconfig.json file.

Usage in an editor

Using Visual Studio, you can get auto-completion if you import the schema in your .JSON file like this:

{
  "$schema": "https://gist.githubusercontent.com/natemcmaster/0bdee16450f8ec1823f2c11af880ceeb/raw/runtimeconfig.template.schema.json"
}

Use these links based on your file type:
