Debugging Apps for SharePoint Online on a non-development site collection

    Thank you for your page. What I do not understand is that your sample in the final screenshot is written in code-behind, resp. C#. I thought that is impossible in Apps for SharePoint 2013. Apps in SP2013 only can run client-side code, like Javascript?!

      Hi Sausal,

      You can use C# in your SharePoint 2013 Apps. In fact, you have 3 types of Apps. Only the “SharePoint Hosted” model uses JS and HTML-only. The other 2 (Auto-hosted and Provider hosted) allow you to use C#. Check this image:

      Good luck!

    Hi everybody,

    I am very new in SharePoint. I want to make a simple project in Visual Studio 2012 then deploy it into SharePoint 2013 and use in our company.

    We have Microsoft Server 2012 DataCenter + SQL 2012 + SharePoint 2013

    I made a built-in app(document process) in SharePoint UI but

    i must develop a project which description likes :

    -can create tasks
    -each task must have begin+end dates
    -each task can be assigned to specific users
    -before the end date system will send warning mails to assigned users automatically
    -we can add attachments
    -assigned users can change their status as waiting, completed etc.

    Do i have to develop project on SharePoint Server or can i develop in my personal machine and deploy to SP Server?

    I am in war almost 1 week.

    Any help?

    Thanks in advance.

    Hi Alexandre,

    I’ve run this exact script however it is still giving me the same error when trying to deploy. I even tried this with an empty solution and I continue to receive the “Error occurred in deployment step ‘Install app for SharePoint’: Sideloading of apps is not enabled on this site”.
    I’m working in a sandbox environment.

    Should I be doing something after running the script?
    Any ideas?

    Thanks in advance,
