Performance messurement on Windows Phone app (ARM)

Question

I want to create a tool for my app performance measurement, something that I can put in sort of section and it will take a timestamp at the beginning and at the end, and then it will write to log the time delta.

However I don't want this functionality in my Production version (I want those measurements to be excluded from the compilation on Production) - I want them only on Debug mode...

I have looked at several AOT libraries, such as Postsharp , but they cost money and also most of them (including PostSharp) don't supports ARM architecture.

Any help will be appreciated.

Eventually I came with something like this, which is a singletone when you are not in debug and normal instantse when you are: Usage:

using(PerfMesureHandler.Get("Something to meassure")))
{
    //Code to measure
}

Code:

    public class PerfMesureHandler: IDisposable
        {
            private PerfMesureHandler(string topic, string methodName , int lineNumber )
            {
    #if DEBUG
                _methodName = methodName;
                _lineNumber = lineNumber;
                _topic = topic;   
                _stopwatch = new Stopwatch();
                _stopwatch.Start();
    #endif
            }

            private string _topic;
            private static PerfMesureHandler_singleton;
            private Stopwatch _stopwatch;
            private int _lineNumber;
            private string _methodName;


            public static PerfMesureHandler Start(string topic, [CallerMemberName] string methodName = "", [CallerLineNumber] int lineNumber = 0)
            {
                PerfMesureHandler= null;
    #if DEBUG
                result = new PerfMesureHandler(topic, methodName, lineNumber);
    #else
                if (_singleton == null)
                {
                    _singleton = new PerfMesureHandler(topic, methodName, lineNumber);
                }
                result = _singleton;       
    #endif
                return result;
            }

        public void Dispose()
        {
#if DEBUG
            _stopwatch.Stop();
            //Write to log...
            string msg = $"topic: {_topic}, time:  {_stopwatch.ElapsedMilliseconds}, method: {_methodName}, line: {_lineNumber}";
            Console.WriteLine(msg)
#endif
        }        

}
