What is the best code compare tool for VB.NET?

What is the best source code comparison and file differencing tool? I want to compare two source code files to see what is the difference between two files. I know WinMerge can do this, but I want to know what is the best code compare tool on Visual Studio platform? Thanks

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Visual Source Safe
Team Foundation Studio is also good.

As for the best, well, there are a number of good ones out there on the market (and LOTS of opinions) - those should be a good start though.

Just for pure comparison of two versions of a source file, the best tool I've used is something called "Beyond Compare" by Scooter Software (http://www.scootersoftware.com/)

This works for any two files in text format...

I use it to maintain test versus production versions of web sites... you can quickly look at a set of files in two directories and see the ones that are different.. then you can look inside two individual files and see the specific differences between them..

The tool is very fast and fairly straightforward to use.

Hi gr8life;

I have found this tool to be excelent UltraCompare, it is a stand alone tool or can be added to there other products as a add in. You can download a trial version to see if you like it.


UltraCompare Professional is a powerful compare/merge application loaded with features to enable users to track differences between files, directories, and .zip archives! File Compare features include text and binary compare of two or three files at a time and users can merge differences between compared files.

Folder Compare supports comparison of local/network directories (and subdirectories with recursive compare) and .zip archives as well and users may merge differences between them. With automatic integration with UltraEdit-32 or UEStudio '05, UltraCompare Professional is a tool no user should be without!

Sorry heyday2004; I placed the wrong name to my last post it was intended for you. That is what happens when you work on multiple threads at the same time.
