We provide an extension for Visual Studio 2015 and Visual Studio 2017 that makes it easy to create an App Store application. You can download the extension here. (Edge users note, the VSIX file may download as a ZIP in which case rename the archive back to .VSIX)

Here is a video that takes you through the whole process

Once installed, you can create an App Store web application by selecting File > New > Project in Visual Studio, choosing .NET Framework 4.5.2 or greater, and navigating to Visual C# > Web from the project template browser:

Once Visual Studio creates the new project, you'll find a readme file in your new project that contains instructions for registering an application with the App Store.

Your new application is an ASP.NET MVC application with Web API and SignalR pre-configured, containing out-of-the-box functionality that demonstrates how to request available data sources, find tags on the data sources, and subscribe to receive updates to tag values in real time. Make sure you have a look around the project to see how these components are used!

Important: If you have not yet registered as an App Store developer, you can do so here.
