Using the DEBUG configuration, I can switch behaviour on and off using this type of syntax:

#if DEBUG

    Console.WriteLine("Debug");

#else

    Console.WriteLine("Not Debug");

#endif

However, if I set up a different configuration, say: TEST then this doesn't work:

#if TEST

    Console.WriteLine("Test");

#else

    Console.WriteLine("Not Test");

#endif

Is there a way to check these?

The DEBUG constant is a special one, and there's a setting for each project in each configuration whether it should be defined. The default is that it's on in Debug and off in Release, but it's completely configurable - open the properties page for a project and look under "Build", and there's a checkbox there saying "Define DEBUG constant."

Thus, defining a new build configuration, does not automatically give you any other compile constants for free. But that doesn't mean you can't create them manually.

To create a compile constant, add it to the list of "Conditional Compilation Symbols" - but make sure to do so in the correct build configuration.

Yes you can use different configurations.
DEBUG symbol is generated automatically if you choose Debug configuration in your configuration manager. You can check it. Go to Your project -> Properties -> Build -> Define DEBUG constant

If you need to use additional constant just enter your own in Conditional compilation symbols.

Steps for your case:

1. Go to Your project -> Properties -> Build


2. Switch configuration to Test


3. Enter TEST to Conditional compilation symbols field

Run your code and enjoy :)
