Free code review software options for ASP.NET and Subversion

Question

Does anyone know about free code review solutions out there (for asp.net)? I am trying to find something that is free or inexpensive for a startup. Also, It would be nice if it had some sort of subversion integration, as this is always a pain to manage manual diff files vs. reviewing the differences between two different revisions.

I would like to have something that is privately run, for privacy, but I don't mind any public options being posted either.

Edit 1

I would like something that will allow peer reviewing at a line by line basis, so that a specific line of code could be discussed or flagged.

Edit 2

It would also be nice to have the code review application that is made in ASP.NET.

Answer 1

Trac would probably fix any concerns you have about viewing diff files, since it has an excellent repository/revision browser built-in. It also probably serves some other needs that you might have (now or soon), like bug tracking and wiki (for documentation).

There is a PeerReviewPlugin for it that may let you do the review you're looking for. I have not tried this plugin out yet, but we do run Trac and Subversion (and VisualSVN on client-side) to manage our source code (mix of mostly .NET, including ASP.NET), and I find just looking at the trac Timeline and reviewing the changes is enough in most cases.

All of this, except VisualSVN, is free. VisualSVN is $50/user (I think there are volume discounts too) and well worthwhile for the time it saves.

Answer 2

Have a look at the SlickEdit tools for Visual Studio and see if the code annotation feature does what you need. It's not a free product though.
