To clarify my question:
Can anyone tell me why below code can't work with mono while the same
code runs well on VS2005?
using System;
using System.Runtime.InteropServices;
namespace test
{
public class Test
{
[DllImport("user32.dll", EntryPoint="CharUpper")]
public static extern string CharUpperA(string lpsz);
public static void Main(string[] argc)
{
System.Console.WriteLine(CharUpperA("abc"));
}
}
}
I have installed wine, and "libuser32.dll.so" (link to user32.dll.so) is
located at /usr/lib/wine, and already configure the ld.so.conf and run
ldconfig. then the "EntryPointNotFoundException" disappear but finally
aborted during executing the native method.
Stacktrace:

Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
