C#: Can't See Methods In DLL - Why

I developed a DLL in C# When I am trying to call it I get: System.EntryPointNotFoundException: Unable to find an entry point named: It means that DLL doens't export any methods visible from DLL. Dumpbin doesn't show any methods either:

dumpbin.exe -exports ActiveXTest.dll
Dump of file ActiveXTest.dll
File Type: DLL
Summary
2000 .reloc
2000 .rsrc
2000 .text

What's wrong? The DLL looks ok.. according to documentation:

Csharp Code:
namespace Kosmala.Michal.ActiveXTest
public static void setHooks()
{
....
}
Here is how I call it:
Csharp Code:
namespace IWFHotkeyStarter
{
class Program
{
[DllImport("D:\work\iwf\_ctrl-tab-modless_dlg_testing\activex\VSProjects\AcriveXSourceCode\bin\Debug\ActiveXTest.dll")]
public extern static void setHooks();
static void Main(string[] args)
{
Program p = new Program();
p.run();
}
private void run(){
Console.WriteLine("run<<");
setHooks();
Console.WriteLine("run>>");
}
}
}
