If it is set to readonly so can never change, doesn't that make it constant?

Microsoft C#. I set a function parameter (string myVar = string.Empty) and got: Default parameter value for 'myVar' must be a compile-time constant I fail to see how anything could be more constant than string.Empty.... :laugh:

Ok, to clarify. The web/app config files of themselves are ok. Better than Registry entries ;) Working with them, however, is a pain. There's very little intellisense, and finding out what you need to add is difficult. Yes, I am proposing something better - Visual Studio should have a GUI tool to create these files, with drop-down menus of choices, check-boxes for true/false options, etc.

These files are a pain to work with, are full of meaningless gibberish, and we are expected to add this guff without any support from Visual Studio... Does anyone know every section and item that a web config file can hold?

It also amazes me that Citrix got installed in so many places - must be the CEO who bought it on the basis of "zero admin costs" and "reducing PC estate" claims.... Every infrastructure team I've ever spoke to about it HATE it and spend more time supporting it than they ever did with proper PC desktops....
