Create an ASP.NET Web Application as the Office 365 AddIn Taskbar

Question

Although C # and others are listed as a possible language, all the samples I found show how to create an AddIn taskbar using only HTML5 / JavaScript.

I already went through all this:

• How to create your first taskbar application using the Napa Office 365 development tools .
• Create a basic SharePoint application using Office 365 development tools Napa
• How to create the first email app for Outlook using the Napa Office 365 development tools .
• How to create the first Excel content app using Office 365 development tools Napa

and others, and they are all HTML5 / JavaScript! Even MSDN samples are just HTML5 / JavaScript!

How can I talk to the ASP.NET web application with Office 365 so that it can manage the taskbar and edit the selected text?

Answer 1

Finally, I did it! This is not difficult. First, you must use Visual Studio. When you develop directly from a browser, download and open this project in Visual Studio. You can follow this example to make a very simple example.

• Build an HTML5 / JavaScript application like in “How to” (first link)
• Add a new ASPX page to the Home folder
• Open the xml application in the Solution folder
• Here you can change the source location to a new ASPX web page.
• Launch the application
