NJsonSchema | JSON Schema reader , generator and validator for .NET | JSON Processing library

I'm using Swashbuckle.AspNetCore.Swagger to generate a swagger document and then using NSwag to generate a C# SDK.

I have a couple classes where I use a Dictionary to hold miscellaneous properties.

I have a DotNetCore Web Api and its client is a UWP APP where client is connected with api through generated Nswag file. I have a class DropDownBase in my api side which is used as a base class for many different kind of dropdown classes, and it was made to hold the common properties across all dropdown classes. Here I will show you one of those child class called Caliber.

I've managed to boil down my test to a simple command:

I create a simple .net5 web api. Then I get the great Rico Suter's Nswag.aspnetcore and tweak it for get my application to create the swagger.json file

In the scaffolded controller I write another PUT action that TAKES AN OBJECT parameter (the simplest I can)

I have a Json schema and can use NJsonSchema.CodeGeneration.CSharp to create classes corresponding to it. So if I have json which conforms to the schema, I should be able to easily parse it into a collection of objects whose classes are the classes generated from the schema?

So how can I do this - parse json and get out C# class objects that correspond to the objects in the json (as define by the schema)?

As an example - if the schema defines a first object definition which is an array of a second object definition, then I would like to be able to parse it in such a way that the output is an instance of the class corresponding to the first object definition and it has a member which is a List of instances of the class corresponding to the second definition. It seems that the schema knows all the information required to do this, so it should be a single line - I appreciate I could do long-hand parsing (eg converting each item in the array) to achieve the same result.

I would think this would be a primary purpose of having C# classes generated from a schema, so what's the magic method I'm missing?

I'm also happy to write C# classes and generate a schema from that if it's a more workable solution.

I've used NJsonSchema but happy to use any other C# json schema and code generation technique that achieves the same end.

UPDATE: After discussion I've seen that if NJsonSchema is used to generate classes from the schema, the TypeScript version of those classes each have a fromJS method which sounds like what I want but they're missing from the C# version. I'm happy to use something other than NJsonSchema to generate classes from schema if it provides a solution.

I have used NSwagStudio to generate client proxy in c#. I saved the project into an .nswag file. I have added it to my .net core console app. I then use the following command in package manager console nswag.cmd run .\client.nswag /runtime:NetCore31

I get

I'm using NSwag and trying to convert an OpenAPI JSON document to version 2. This is my configuration:

I am using NJsonSchema CsharpGenerator 10.1.24 and have the below schema I am using to generate a POCO:

When I attempt to load the SwaggerUI when visiting localhost:5001/swagger I receive an error in the SwaggerUI that alerts me of the following:

Fetch error undefined /swagger/v1/swagger.json

It is also interesting to note that my .NET application is raising an error as well when visiting the SwaggerUI.
