Set up an app for testing on an Azure DevTest Labs VM

This article shows how to set up an application for testing from an Azure DevTest Labs virtual machine (VM). In this example, you use Visual Studio to publish an app to an Azure file share. Then you access the file share from a lab VM for testing.

Prerequisites

• An Azure account with an active subscription. Create an account for free.
• A Windows-based DevTest Labs VM to use for testing the app.
• Visual Studio installed on a different workstation.
• A file share created in your lab's Azure Storage Account.
• The file share mounted to your Visual Studio workstation, and to the lab VM you want to use for testing.

Publish your app from Visual Studio

First, publish an app from Visual Studio to your Azure file share.

1. Open Visual Studio, and choose Create a new project in the Start window.
