Over two years ago, Chromium announced that they would be deprecating support for Chrome apps, but we continued to support our Chrome app until November 2017. Since then, new features and bug fixes have been released exclusively in our native Mac, Windows, and Linux apps. (Hint: download our free native apps to get the latest version of Postman!)
Although Postman was introduced first as a chrome application and was powerful earlier on, we highly recommend downloading postman as an application for your operative system(native application) rather than as an extension for chrome.

This tutorial demonstrates how to create backend services using ASP.NET Core to support native mobile apps. It uses the Xamarin.Forms TodoRest app as its native client, which includes separate native clients for Android, iOS, and Windows. You can follow the linked tutorial to create the native app (and install the necessary free Xamarin tools), as well as download the Xamarin sample solution. The Xamarin sample includes an ASP.NET Core Web API services project, which this article's ASP.NET Core app replaces (with no changes required by the client).
