C# SFML Visual Studio - Error on Build

[random_canadian]

Following the steps given on this thread (http://en.sfml-dev.org/forums/index.php?topic=7674.0), I managed to setup SFML.Net 2.0 with Visual Studio C# 2012. However, I get the following error whenever I actually try to build something that references the SFML library...

An unhandled exception of type 'System.BadImageFormatException' occurred in mscorlib.dll

Additional information: Could not load file or assembly 'sfmlnet-graphics-2, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. An attempt was made to load a program with an incorrect format.

According to this page (http://msdn.microsoft.com/en-us/library/system.badimageformatexception.aspx), the file image of the sfmlnet-graphics-2 DLL is "invalid."

The exception that is thrown when the file image of a dynamic link library (DLL) or an executable program is invalid.

Any ideas about what I may have done wrong?
Thanks!

EDIT: After some more research it appears this is a problem with discrepancies between x64 or x86 builds (http://en.sfml-dev.org/forums/index.php?topic=9917.0). If I change the CPU settings to "prefer x64" (I am using 64-bit SFML), then the build succeeds. So my question is what happens if my user wants to run the game on a x86 system? Do I need to include DLLs of both x64 and x86 versions of SFML? How do I do this?

EDIT #2: Here's yet another thread about this issue (http://en.sfml-dev.org/forums/index.php?topic=2405.0) but, my question remains. What is the permanent solution?

You must use the x86 DLLs for the x86 build of your application, and the x64 DLLs for the x64 build of your application. Simple.

Fair enough 
Thanks Laurent.

Hey, I had the same problems as random_canadian. Then I tried to run a 32Bit and 64Bit sfml project,
but I always get the same Exception:
"BadImageFormatException"
"HRESULT: 0x8007000B"

Here's my code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using SFML;
using SFML.Graphics;

namespace SFML.Net_Test
{
    class Program
    {
        static void Main()
        {
            RenderWindow window = new RenderWindow(new Window.VideoMode(200,200), "test");
            Window.Window win = new Window.Window(new Window.VideoMode(200, 200), "test");
            CircleShape cs = new CircleShape(100.0f);
            cs.FillColor = Color.Green;

            while (win.IsOpen())
            {
               
            }
        }
    }
}

Phew!  I'm really glad I stumbled across this post.  Same exact problem on my end, and same exact solution.

Thanks so much!
