I have built a simple Silverlight control and a WebPart to go with it. This is my first SharePoint project and I was very confused most of the time (I.e. I am a Sharepoint noob) :-)
The Silverlight Control and the webPart live in a sandboxed solution. After deletion of this solution both are still available in Sharepoint. I gathered this is normal...
I found one how-to on removing files which were provisioned (can't remember the url) but this solution didn't work - I think that was due to the fact that the solution was intended for full-trust-solutions whereas I am using a sandboxed solution.
Any good hint on how I would remove the files of the solution upon deletion of the solution?
