Log method information

I have been spending a lot of time trying to find a library that allows to log information about the methods that are being executed. Somehow I feel that all of them are too invasive. Is there any library or code that makes this so simple that I only need to add a decorator/attribute to the method?

Here what I would like to have:

internal class Calculator
{
    [CustomInterceptor]
    public static int Add(int a, int b)
    {
        return a + b;
    }
}

internal class CustomInterceptor : Attribute
{
     //here some implementation
}

static void Main(string[] args)
{   
    var result = Calculator.Add(10, 2);
    Console.WriteLine($"Result : {result}");
}

Desired output

Before Add
Result 12
After Add

If this can be done with Reflection, please I would prefer that approach since that would imply no need for third party libraries.

Thanks in advance.
