I have compiled the OpenSSL package by hand. So, it has generated two
libraries:
-libeay32.dll
-ssleay32.dll

When i run the following code snippet, the system raise the
System.DllNotFoundException:

one.cs---------------------------------------------
[DllImport("ssleay32.dll")] 
public static extern int some_function_name (string arg);
..

some_function_name("value");
-----------------------------------------------------

and running this other code snippet:

two.cs-----------------------------------------------
[DllImport("Kernel32", SetLastError = true)]
public extern static int LoadLibrary(string name);
..       
Console.WriteLine("libeay32.dll: "  + LoadLibrary("libeay32.dll").ToString ());
Console.WriteLine("ssleay32.dll: " + LoadLibrary("ssleay32.dll").ToString ());
.. 
-----------------------------------------------------
command> mono testing.exe
libeay32.dll: 1641545728
ssleay32.dll: 0

the handler to the seccond library seems to be bad.

I HAVE FOUND THE FOLLOWING SOLUTION:
commnad> del "c:\mono path\bin\libeay32.dll"

and, if i run the test again:

command> mono testing.exe
libeay32.dll: 21037056
ssleay32.dll: 22347776

and one.exe works fine!
