C# if/then directives for debug vs release
DEBUG/_DEBUG should be defined in VS already. Remove the #define DEBUG in your code. Set preprocessors in the build configuration for that specific build. The reason it prints “Mode=Debug” is because of your #define and then skips the elif. The right way to check is: #if DEBUG Console.WriteLine(“Mode=Debug”); #else Console.WriteLine(“Mode=Release”); #endif Don’t check for RELEASE.
