I would like to set an application page as a home page in a team site sharepoint 2013 it's possible? I would like to do that in the feature activated event.
We cannot set page (
http://[servername]/[projectname]/_layouts/Pages/Summary/Default.aspx) to website welcome page because this page not the part of our current site.
You can set a page to web site welcome page that has the part of our current website. To do this you have to go Site Actions->Site Settings-> Welcome Page (under Look and Feel), set your page as welcome page that has the part of our site. For this you have enabled publishing feature on site.
