Why compiling similar example, - getting

error: 'Dl' was not declared in this scope

though I have done everything like here, but cannot declare Dl Plugin; object in Upp CONSOLE_APP_MAIN.

p.s.
Details: using upp-v.13664 x32, in Console Project (with Core package in package organizer).
DLL was made from C#.NET-source:

using System;
using System.IO;
using System.Runtime.InteropServices;
using RGiesecke.DllExport;

namespace Plugins
{
    public class Plugins
    {   // CallingConvention.StdCall
        [DllExport("OnPluginStart", CallingConvention = CallingConvention.Cdecl)]
        public static bool OnPluginStart()
        {				
            using (var file = new StreamWriter(@"c:\\pluginLog.txt", true))
            {
                file.WriteLine("OnPluginStart");
            }			
	    return true;
        }
    }
}

compiled with CMD Line:
Quote:

C:\Windows\Microsoft.NET\Framework\v3.5\csc.exe /t:library /platform:x86 /r:C:\Test\UnmanagedExports\lib\net\RGiesecke.DllExport.Meta data.dll /out:C:\Plugins.dll C:\Plugins.cs

MY .dli

FN(bool, OnPluginStart,(void))

Another problem, In Upp CONSOLE_APP_MAIN with

	
	bool nn= PLUGINS().Load();
	Cout() << nn << '\n';

- getting false.
And with

bool retval= PLUGINS().Load("C:\\Plugins.dll");

- Upp CONSOLE_APP_MAIN crashes

P.P.S.
Sorry, if am not right posting to this topic - just my problem seemed to be simply another problem under the same title...

Best regards.
