I am about to implement an Entity Framework 6 design with a repository and unit of work.
There are so many articles around and I\'m not sure what the best advice is:
I always use UoW with EF code first. I find it more performant and easier tot manage your contexts, to prevent memory leaking and such. You can find an example of my workaround on my github: http://www.github.com/stefchri in the RADAR project.
If you have any questions about it feel free to ask them.
