Java naming conventions states that constants, declared as static and final, must be named all uppercase. Eclipse will automatically turn these guys in blue and italic. Here is an example of what it will look like in Eclipse:

public class Sandbox {
    public static final String CONSTANT_VALUE = "Hello World!";
    public static void main(String[] args) {

That's pretty neat. You cannot miss a constant, even if it is not fully qualified (it has to be if it is from another class, of course).

According to Microsoft's naming conventions, constants in C# (that use the const keyword, being compile time constants) have to be named using Pascal Case. Visual Studio doesn't color it any special way, meaning that if it is not qualified, you cannot know if it is a constant, a propertie, a variable...

Here is what it looks like:

class Sandbox
    const String ConstantValue = "Hello World!");

    static void Main(string[] args)

I find this a bit disturbing, as constant should always be easy to recognize. Well, at least that what I think. I was not able to find any option in Visual Studio to change this. A good start is to always fully qualify constants, in this case using Sandbox.ConstantValue (same advice goes for this keyword, I always use it, even when unnecessary).

You can find some more details on this subject here on stackoverflow.
