# BitDiffer, anyone?

By Roy Osherove January 15, 2008 In [.NET](https://osherove.com/blog/category/net), [Cool Tools](https://osherove.com/blog/category/cool-tools), [General Software Devel...](https://osherove.com/blog/category/general-software-devel)

**Historical article** · Originally published January 15, 2008; technical details may be outdated.

Note to self: check out [BitDiffer](http://www.bitwidgets.com/). Looks pretty awesome.

> "Ever wonder what really changed in that DLL you are about to release to production? Would you like to check a 3rd party library for breaking changes before referencing it? Would it be helpful to integrate an automatically generated change report - at the assembly binary level - in your deployment and migration process?

> BitDiffer allows you to compare multiple versions of assemblies for all types of changes and drill down to find the smallest changes, public or private."

Anyone used it? know any comparable tools?

update: I found this one on [Jeremy Miller's blog](http://codebetter.com/blogs/jeremy.miller/). it has a Lunge ad on the top left (codebetter.com actually has it). Hmm. Perhaps Typemock should be [advertising over at the lounge](http://www.infozerk.com/thelounge/) too...hmm?
