We want to make an app available in SharePoint OnPrem, we want to onpremify it. Rethink SharePoint apps and provisioning SharePoint artifacts. It has been a while since I updated my blog – Chuvash.eu. I had my vacation, I visited the sunny and green Chuvashia. Now I am back and I am looking forward to an awesome SharePoint Autumn. One of the first things I had to deal with in this SharePoint Autumn was Onpremifying of a SharePoint Online App.

This is an open question about the domains for SharePoint apps. On Technet: Configure an environment for apps for SharePoint (SharePoint 2013) we can read the following: You must configure a new name in Domain Name Services (DNS) to host the apps. To help improve security, the domain name should not be a subdomain of the domain that hosts the SharePoint sites. For example, if the SharePoint sites are at Contoso.

In my project I deploy some apps directly through the ObjectModel directly with PowerShell. The apps are built with TFS I have a script that installs or updates apps if there is a new version of the app. Previously I used Import-SPAppPackage to compare the version and productid with an existing app instance, but often I get this error: The provided App differs from another App with the same version and product ID.

Have you noticed that you can right-click a web application project in Visual Studio and convert it to a provider hosted app? Well why not? Basically your own website and a SharePoint manifest is all what you need for a provider hosted app. This discovery today made me think about all legacy web apps out there that can be converted to SharePoint apps. Traditionally we had to add plain links to external applications or embed them into an IFrame by hardcoding it in an .

Recently I had an exciting mail conversation with Thomas Deutsch. He came up with an idea how to fasten the development of apps. This smart approach is called “Provider Hosted First”. See Thomas’ original blog post. Here are some highlights: What you actually do is a local website which runs in grunt server: localhost:9000 ```Then a SharePoint-hosted app is created with an SPAppIframe that refers to that local app site.
