Missing package references & Missing FetchStrategy passing of arguments to Find methods

I'm not sure if this done correctly, so let me know what needs to be done differently. :)

The purpose of this PR is when I cloned the project, I had to restore nuget packages (which added those configurations), and then I had to make sure the package.config contained references to the required DLLs. (EntityFramework & MongoDB). Otherwise the project was not buildable on my end. 

The 2nd commit is to include the FetchStrategy when using the Find query.

Thanks!
