From C# to .d.ts file

This extension will automatically generate .d.ts files from any C#/VB file you specify. It will turn the following C# class into a TypeScript interface.

class Customer
{
    public int Id { get; set; }
    public string Name { get; set; }
    public IEnumerable<string> Tags { get; set; }
}

Becomes this .d.ts file:

declare module server {
	interface customer {
		id: number;
		name: string;
		tags: string[];
	}
}

The generated .d.ts file can then be consumed from your own TypeScript files by referencing server.<typeName> interfaces.

Generate d.ts file from C#/VB

To generate a .d.ts file, right-click any .cs or .vb file and select Generate TypeScript Definition.

A .d.ts file is created and nested under the parent C#/VB file.

Every time the C#/VB file is modified and saved, the content of the .d.ts file is updated to reflect the changes.
