Is there any way to programmatically generate a JSON schema from a C# class?

Something which we can do manually using http://www.jsonschema.net/

Another option which supports generating JSON Schema v4 is NJsonSchema:

var schema = JsonSchema.FromType<Person>();
var schemaJson = schema.ToJson();

The library can be installed via NuGet.

Update for NJsonSchema v9.4.3+:

using NJsonSchema;

var schema = await JsonSchema.FromTypeAsync<Person>();
var schemaJson = schema.ToJson();
