Telerik Reporting may be what you're looking for. Unfortunately in my experience the forum isn't very helpful and there's not many examples to get you going with regard to the newer version of the Entity Framework. Telerik Reporting doesn't directly support the DbContext, but it works with the older ObjectContext or has a "Business Object" adapter that can also be set up to work with Entity Framework.
I downloaded the trial version it and got very frustrated trying to get it to work. This course on pluralsight got me going. They're currently offering 200 free minutes so you can probably do the course for free (it's 187 minutes). It got me up and running much faster than trying to work it out for myself and waiting for zero response on the forum.
Once you know how to use it, the reports are pretty good IMO.
