How to tell if calling assembly is in DEBUG mode from compiled referenced lib

I have a referenced library, inside there I want to perform a different action if the assembly that references it is in DEBUG/RELEASE mode.

Is it possible to switch on the condition that the calling assembly is in DEBUG/RELEASE mode?

Is there a way to do this without resorting to something like:

bool debug = false;

#if DEBUG
debug = true;
#endif

referencedlib.someclass.debug = debug;

The referencing assembly will always be the starting point of the application (i.e. web application.

The accepted answer is correct. Here's an alternative version that skips the iteration stage and is provided as an extension method:

public static class AssemblyExtensions
{
    public static bool IsDebugBuild(this Assembly assembly)
    {
        if (assembly == null)
        {
            throw new ArgumentNullException(nameof(assembly));
        }

        return assembly.GetCustomAttribute<DebuggableAttribute>()?.IsJITTrackingEnabled ?? false;
    }
}

Google says it is very simple. You get the information from the DebuggableAttribute of the assembly in question:

IsAssemblyDebugBuild(Assembly.GetCallingAssembly());

private bool IsAssemblyDebugBuild(Assembly assembly)
{
    foreach (var attribute in assembly.GetCustomAttributes(false))
    {
        var debuggableAttribute = attribute as DebuggableAttribute;
        if(debuggableAttribute != null)
        {
            return debuggableAttribute.IsJITTrackingEnabled;
        }
    }
    return false;
}

You can use reflection to get the calling assembly and use this method to check if it is in debug mode.
