Let's first describe my work context:
I am working on SharePoint 2013 on-premise
I have created an App for a SharePoint 2013 Solution using Visual Studio 2012 with provider-hosted option. Two projects have been added: a SharePoint app project and a Web Application Project.
If I add an aspx page to the SharePoint App Project, the
aspx.cs page is not generated.
Is there a way to add code behind files to my SharePoint App Project?
