Hi guys!

Please bare with me, this is my first attempt at developing something... ever!! 

So I've got SharePoint Online running, I have a development site, I have napa installed... I've created a new project in napa and opened it up in Visual Studio 2013. I've created a very basic RSS reader using C# that pulls the latest 5 headlines from the BBC and displays them in labels... when debugging it all looks okay...

I've since deployed the app from visual studio,  published it using napa and added it to my Web Applications App Catalog site.

I now have the option within my default team site to add the app... I do so, I trust the app as it's installing but all that displays is this:

and not my RSS feed!

I feel like i'm pretty close, and would appreciate any assistance getting this working!

Many thanks

Hi Griff,

Per my understanding, you create a SharePoint Hosted app using Napa tool from SharePoint online site, then open this project in Visual Studio 2013, add a component which is created using C#, after app deployed, the RSS content doesnt display.

By design, C# is not supported when developing a SharePoint Hosted App:

As a workaround, you can create your RSS reader using JavaScript instead, it will work in your SharePoint Hosted App.

Some jQuery RSS reader plugins for your reference:
