UseDefaultExport breaks interface inheritance

When using the API, adding the UseDefaultExport option breaks the class inheritance on extracted TypeScript classes.

public interface IId
{
    int Id { get; set; }
}

public interface IIdentifier
{
    string Identifier { get; set; }
}

public class ProductDto : IId, IIdentifier
{
    public int Id { get; set; }
    public string Identifier { get; set; }
}

var gen = new Generator
{
    Options =
    {
        BaseOutputDirectory = "./types",
        UseDefaultExport = true // adding this option
    }
};

internal class MyGenerationSpec : GenerationSpec
{
    public MyGenerationSpec()
    {
        AddClass<ProductDto>();
    }
}

gen.Generate(new List<GenerationSpec>(new[] { new MyGenerationSpec() }));

Expected :

/**
 * This is a TypeGen auto-generated file.
 * Any changes made to this file can be lost when this file is regenerated.
 */

import IId from "./i-id";
import IIdentifier from "./i-identifier";

class ProductDto implements IId, IIdentifier {
    id: number;
    identifier: string;
}
export default ProductDto;

Actual:

/**
 * This is a TypeGen auto-generated file.
 * Any changes made to this file can be lost when this file is regenerated.
 */

import IId from "./i-id";
import IIdentifier from "./i-identifier";

class ProductDto { // => missing implements IId, IIdentifier 
    id: number;
    identifier: string;
}
export default ProductDto;

Done with :

• net6.0 console app
• TypeGen 3.0.0

+1 on this as it this wasn't the behaviour on last versions of typegen.

It's super annoying, specially if your your tsconfig.json file has "noUnusedLocals" set to true, the typescript compilation will fail.

P.S. - I think that it doesn't even matter if UseDefaultExport flag is set to true or false, it will fail to correctly link everything anyway.

This is a major issue - When defining a C# class that implements an interface, the interface is not implemented on the TypeScript class

Should be fixed in 4.3.0.
