I have an object that requires a lot of initialization (1-2 seconds on a beefy machine). Though once it is initialized it only takes about 20 miliseconds to do a typical "job" In order to prevent it from being re-initialized every time an app wants to use it (which could be 50 times a second or not at all for minutes in typical usage), ...

I've used .resx files in the past to store text files and other things - queries for example. It works great because I can say Resources.Queries.BlahQuery. (Yes, I know we should probably used stored procedures, but that's another story...) I'll never be doing any localization on these resources. Is this a bad idea? Am I misusing .NET ...

In C#, I have added a context menu to a third-p...
