I have been learning about SharePoint and Provider-Hosted Apps recently. Based on some videos and tutorials, I have seen most having a site with a SPHostURL. I was able to recreate that as well.
Then heard displaying multiple apps in an iFrame. (See image)
When clicking on a hyperlink to the app, the app displays into the iFrame. The right side has the SharePoint calendar, or other client side lists that the Provider-Hosted app can communicate with,e.g. selecting dates, looking up contact details, notes.
Is this method easily possible and is it effectively?
What is the best approach for Provider Hosted Apps?
