I need to be able to deploy bunch of aspx files when a site (sub-site aka web) is provisioned. I added a feature but it seems whole feature thing has changed with vs 2010 or sp2010. I am totally lost. All I want to do is to deploy these pages when a web is provisioned. Is it possible?
You can't drop aspx pages into SharePoint per say. If you want to add functionality, some of the options are:
1) Using Web Parts - probably the most popular method
2) User Controls
At the end of the day, you will create it as a Feature using VSeWSS 3.0 in VS and packaging/deploying it as a solution. Steer clear of trying to hack this up in SharePoint Designer - for one, you won't have source control like you have with a Feature.
