Find assembly name from CallerFilePathAttribute

I have a class 

public class DataLayerFromOutside
{
    public string DataLayerMethod(string dataLayerMethodParameter)
    {
        NLogging.Info("FromMethod");
        return "Hi";
    }
}

This class is within SampleClassLibrary. I have a controller from which this method is called.

[LogActionFilter]
public class SampleController : ApiController
{
    // GET api/sample
    public string Get()
    {
        DataLayerFromOutside businessLayer = new DataLayerFromOutside();
        NLogging.Info("Info ");
        return businessLayer.DataLayerMethod("Hi");
    }

This controller is within another dll 'TestLoggingEntryAndExit'.

I have an NLogging class where we log all activities.This class contains a method

public static void Info(string message, Exception exception = null, [CallerFilePathAttribute] string callerPath = "", [CallerMemberName] string callerMember = "", [CallerLineNumber] int callerLine = 0)
{
    Log(LogLevel.Info, message,null, exception, callerPath, callerMember, callerLine);
}

I want to find the assembly name from which this Info method is called.

How can I find the assembly name from CallerFilePathAttribute?

This isn't possible with the caller info attributes. There is a feature request for more caller info attributes on the backlog of Roslyn

Currently the only way is to use reflection:

//get assembly of caller
var assembly = new StackTrace().GetFrame(1, false).GetMethod().DeclaringType.Assembly;

This isn't possible in .NET standard (.NET Core) yet. It should be there in Netstandard 2.0

edit: @Eilon is right. This isn't a reliable way. Adding [MethodImpl(MethodImplOptions.NoInlining)] is helping a lot, but no guarantees

edit 2: another reliable way (and more complicated), is to write/use a Fody plugin. See Fody website
