What theme are you using?

What is your question?

I am using c# to export some classes with a tool:
https://github.com/RicoSuter/NJsonSchema

Which seems to export with:
https://json-schema.org/draft-05

With a property within

{
"$schema":"http://json-schema.org/draft-04/schema#"
}

I had to manually modify and delete $schema property.

@rufreakde Can you provide an example with the $schema property and explain how it doesn't work? The schema you sent seems to work fine at first glance, and if I add the $schema property to the top level, it still seems to work.

@nickgros I thought the example worked but somehow the schema references are gone maybe I did something wrong with the playground?

I would need to modify my exporter I will come to it maybe in the upcoming days then I can post a full example.

Okay crazy. It works now... I am very surprised. I should have screenshottet the error message! This was my test.
