High Trust Provider hosted Apps (on IIS locally):

I deploy my app on SharePoint like (http://servername:port) and I found my app in root of site but when i entered the subsite like (http://servername:port/en) or any other subsite I cannot find the app in apps available and also cannot find my app part in apps also.

How I can deploy my app to all site collection include subsites and sub of subsites like when deploy webpart.

I already Install apps from store and I can found them in all subsites like (Google Maps for SharePoint).

You need to deploy your apps using App Catalog for your web application. Then your app will be available on subsites too.

To configure your app catalog refer:


  • I did it as mention in link but I cannot find the app-part in subsite and when add app to subsite its gives me exception : The provided App differs from another App with the same version and product ID.

  • First try to remove all instance of app where it is installed. If you are not able to remove it manually, use the powershell. Then in app manifest change product id to new guid and redeploy your app to app catalogue and then add it to subsite. Commented Dec 23, 2013 at 6:02
