How to build

Running the following commands will create NuGet packages in the root directory (in this example for version 3.0.0):

.\update-version.ps1 3.0.0

How to use

  1. Add the TypeGen NuGet package to your project. The dotnet-typegen package can be used for a .NET tool.

  2. Select the types to export to TypeScript:

// using attributes

public class ProductDto
    public decimal Price { get; set; }
    public string[] Tags { get; set; }

// or using a specification file (a "generation spec") created anywhere in your project

public class MyGenerationSpec : GenerationSpec
    public MyGenerationSpec()
  1. If you're using a generation spec, create a file named tgconfig.json directly in your project folder with the following content:
  "generationSpecs": ["MyGenerationSpec"]
  1. Build your project and type TypeGen generate or TypeGen -p "MyProjectName" generate (depending on the current working directory of the PM Console) into the Package Manager Console (you might need to restart Visual Studio), or dotnet typegen generate in the system console to use the .NET tool.

After completing the above, a single TypeScript file (named product-dto.ts) should be generated in your project's root directory with the following content:

export class ProductDto {
    price: number;
    tags: string[];
