Let me ask some follow up questions. You are currently maintaining an existing TypeScript API, I presume this API is client side in a web application? Or is this TypeScript running on the server via a console app?
If it's on the client in a web application you will need to use a standard HTTP Post to send the file back to the server (which i'm presuming is the asp.net MVC application). Let me know if this is what you're looking for and I will help you with your solution.
