Buenas,
some time ago I spoke of the possibility of Configure WinMerge to be used as a tool by default for Diff and Merge within Visual Studio 2010. With Visual Studio 2012 has been incorporated a new Diff and Merge tool that the truth is that it works very well (something talked here about this new tool)
Now, if we want to compare 2 files in a simple way, because the IDE is not all intuitive to find this option.Fortunately, the command line gives us the answer in the following format:
devenv.exe/diff Compares two files. Takes four parameters:
SourceFile, TargetFile, SourceDisplayName (optional),
TargetDisplayName (optional)
And then launch a command of style
C:\Program Files (x 86) \Microsoft Visual Studio 11.0\Common7\IDE > devenv.exe/diff
“e:\source.txt” “e:\target.txt””SOURCE””TARGET”
We will see something similar to the following
