Cant use SPContext.Current.Site in Sandbox Feature Receiver
This may be common knowledge to you Sandbox Solution pros out there, but I banged my head against it for a while today and felt like sharing.
I was attempting to grab the current site using SPContext.Current.Site like I normally do, but I kept getting the generic Sandbox error tell me I was outside the confines of my sandbox. This seems to only occur when dealing with feature receivers, but I am not positive about that.
As a work around, you can get the current site through the properties object as such.
SPSite siteCollection = properties.Feature.Parent as SPSite;
Happy coding!
