The desire is to do something like: var stringItem = new IItem<string>(); var numberItem = new IItem<int>(); var items = new List<IItem<T>>(); //T of course doesn't accomplish what I want items.Add(stringItem); items.Add(numberItem); Something like: inter...
I write unit tests to my code, using Moq as a mocking framework. My code includes calls to the file system, using direct calls to System.IO classes. For instance, File.Exists(...) etc. I'd like to change that code to be more testable, so I should have an interface, say IFile, with a relevant method, say Exists(string path). I know I can ...
In a level editor I've made for my XNA game (editor is also in XNA) I'm allowing to scale Texture2D objects. When the user tries to save the level, I'd like to actually resize the image file on disk so that it doesn't require scaling in the game.

We are currently working on a "data-driven" state machine application. Right now, the state flows are all configured in the database, but none of the decision/business logic is configurable in the DB with our current design. Because of this, the code has to basically "know" the state flow as well, so there's really no point in configur...
