In C#, int and Int32 are the same thing, but I\'ve read a number of times that int is preferred over Int32 with no reason
I'd recommend using Microsoft's StyleCop.
It is like FxCop, but for style-related issues. The default configuration matches Microsoft's internal style guides, but it can be customised for your project.
It can take a bit to get used to, but it definitely makes your code nicer.
You can include it in your build process to automatically check for violations.
