So i was trying to develop an app in a small SharePoint 2013 farm,I use a Virtual Machine with only 4 GB of RAM.
When i tried to deploy the app i got this Error: The requested service, “
Http://Blablalba/AppMng.svc” could not be activated
It happen to be that the server didn’t have enough memory to run the service… since this was a development machine I stopped some services that i didn’t use, one in particular the “SharePoint Search Host Controller” consumes a lot of resources.
After I stopped those services I was able to deploy my app
