I was having an error where planetwroxentities was just giving me an error I fixed this by following steps i found on this site. The only problem is my deleted my bin folder and when I rebuilt the model the bin folder did not get recreated. My question is: is the bin folder needed for this book? if so could I copy and paste the contents of the source bin folder?

Yeah, it's used as it contains the DLLs for Entity Framework, System.Web.Optimization and others.

Using the one from the source folder might work, but it depends on the versions. You may have newer versions referenced in your web.config which means you should either manually update your web.config, or use the one from the source as well.

Depending on how you installed everything, restoring the NuGet packages and recompiling may solve the problem as well.

Cheers,

Imar
