Are there any guidelines for the usage of namespace in big projects?

Are there any commonly accepted guidelines for usage and organization of namespaces in big projects?

Thanks!

MIcrosoft's guidance is CompanyName.TechnologyName[.Feature][.Design].

..

E.g. if your companys name is Sample Software Solutions and you were writing an ATM system then you might have assemblies like:

  • SSS.ATM.Domain
  • SSS.ATM.Data
  • SSS.ATM.Common(an assembly common across ATM)
  • SSS.ATM.Services
  • SSS.ATM.UI SSS.Common (an assembly common across all products)

We would then typically have some unit test assemblies:

  • SSS.ATM.Domain.UT
  • SSS.ATM.Data.UT
  • SSS.ATM.Common.UT
  • SSS.ATM.Services.UT
  • SSS.ATM.UI.UT
  • SSS.Common.UT

And there may also be one or two IT or AT assemblies (Integration / Acceptance testing) e.g.

  • SSS.ATM.Domain.IT (Integration testing the domain)
  • SSS.ATM.UI.AT (Acceptence testing through UI)

Namespaces are mainly just about avoiding Ambiguity with other classes/Objects. And in terms of organization I like to organize UI elements away from other working Function;

tip: To make sure your code is never confused with other objects use a reverse order of a domain name that may be registered for the product. 

com.somecompany.app.*


    com.somecompany.Math;   
                     Math.work(a,b)

    com.somecompany.UI;
                     UI.SomeUserControl
                     UI.AnotherUserControl
                     UI.Forms;


    com.somecompany.Web;

You can try FxCop, there are some rules.

  1. Generally you can make some base prefix (company)

  2. Then add the tiers/modules of the project (DAL, UI, Common, etc)

Then I add folder names to the namespace.

So if my file with MegaUtil class is in prj Common in folder Utils/Misc it will be:

YourCompanyName.Common.Utils.Misc
