C# Project folder naming conventions

Question

I have a project called Data which is a data layer. In this project, all files are just lying in the top folder. I have enumerations, POCOs, repositories, partial classes and so

Answer 1

I tend to use project folders as a way of separating out sub namespaces. So in your case, perhaps a folder called Repositories, which has class in the Data.Repositories namespace. Note, for partial classes, each file needs to be in the same namespace.
