Services that use the http module cannot be imported from the x-shared directory

[MahendraTennakoon]

If a service that makes any HTTP calls is imported from the x-shared folder, the browser console will give the following error.

The HttpModule has been imported into the app.module.ts and added to the imports array. Therefore this cannot be related to that.
