Namespaces and folder structures in c# solutions: how should folders on disk be organised?

Question

First off, let’s agree that namespace should match folder structure and that each language artefact should be in its own file.

I'm not a big fan of nested projects, since it buries projects deep inside a structure and if you need to reuse that project in another application then what do you do, copy/paste the code? I like to follow somewhat of a flat structure but organized by namespace.

This is how I do it:

- DataHelpers\
---Factory\
---DataAccess\
---...
- Components\
--- EmailProcessor\
--- ErrorLogger\
- Desktop\
--- WindowsApp1\
- Services\
--- WindowsService1\
--- WindowsService2\
- WebApps\
--- WebApp1\
--- WebApp2\

Now, inside each major application I have, for example:

- WindowsService1\
--- WindowsService1\ (this contains all *.cs, bin, obj, etc and .csproj file)
--- Solution\ (this contains the .sln file where you link to other projects like ErrorLogger, etc)

I hope that makes sense!
