I'm probably the lone idiot here, but I just purchased Resharper 6 and was using it today to with the code analysis to scan our newest version of a project, and was using the refactoring to change someones parameter values to a less confusing name.
I changed his parameter named "code" to something like "updatedCode" or something to disambiguate it from the others used in the same function.... However! When I did the parameter refactor the default (search in comments and string literals) was checked. This seemed fair enough, I did not however realize that it would change things in my entire project. This changed a "Key" string literal in my DBML autogenerated code -- is this normal or did something go wonky? I would imagine the refactor in comments would probably stick to the same file.
