One thing I have always wanted to compare are the default routes you get with Rails, with the default routes you get with ASP.NET MVC.
GET /Permits Index
GET /Permits/Create Create
POST /Permits/Create Create
GET /Permits/Details/1 Details
GET /Permits/Edit/5 Edit
POST /Permits/Edit/5 Edit
GET /Permits/Delete/5 Delete
Pretty close. Biggest differences are Rails does
for editing a resource while ASP.NET MVC does
And some of the action names are different (new/create, show/details, update/edit, destroy/delete).
Of course you can always change your routing logic in ASP.NET MVC if you want something closer to what they do it in Rails:
Anyways. Just something I have always wanted look at and compare.
