It always works on my machine.

Probably the most common question that the Red Gate developer tools support gets is “Does your X work with Y?” where X is your bit of software and Y is a bit of software made by a different company. This is probably the least answerable question in the known universe. Start with the obvious – “Does X work?” – full stop. Because with millions of possible configurations in Windows, it’s entirely possible that it won’t “work” at all. But I can personally guarantee you that it “works on my machine”! Second of all, what does “work” mean? Several things that come to mind: Finally, as I already mentioned, the question could be about Fear, Uncertainty, and Doubt. For instance, if a new version of Microsoft .NET Framework comes out, there is a doubt that your program will not function correctly with it. I’ve heard of a dutiful network administrator mass-emailing every vendor he has bought any software from when a new version of SQL Server is on the horizon – “Does X work with the new version of SQL Server”? I believe it’s a bit lazy to ask a question this way and you may not get the answer you expect, unless you are perhaps more specific about the particular functionality you are interested in.
