What's the best way to do a bulk namespace rename on a large c# application?

Question

First, a little background.

Currently namespaces and assemblies in our codebase (~60 assemblies, thousands of classes) looks like

WidgetCompany.Depar         


        

Answer 1

If you have ReSharper:

1. Right click project, Properties. Change Default namespace to desired namespace.

2. Right click project, Refactor -> Adjust Namespace to update all the namespaces to use the default namespace

Then just let it do its magic.
