Hi, everybody

First of all, i should say i am new at OpenGL programming and thanks to those who may help to solve my problem :)

The thing is, i was developing an application which is named Articulated Robot Arm (some of you guys may familiar with this). Everything was going perfect, but last night i have upgraded my OS from WinXP to Vista Ultimate 64-bit. I have opened my project to keep going but, i got the following exception in my code.

System.TypeInitializationException was unhandled
  Message="The type initializer for 'CsGL.OSLib' threw an exception."
  Source="csgl"
  TypeName="CsGL.OSLib"

The exception is generated in this section of my code:

public partial class Form1 : Form
    {
        MyView viewRef;
        public Form1()
        {
            InitializeComponent();
            viewRef = new MyView();
            this.viewRef.Parent = OpenGLPanel;
            [B]this.viewRef.Dock = DockStyle.Fill;[/B] // <- Here
            
        }

I really have no idea what the problem is.

Quick diagnosis for : a TypeInitializationException with an inner BadImageFormatException almost always points to a CPU-architecture mismatch between the running process and a native or mixed‑mode library used by CsGL. Moving from 32‑bit XP to 64‑bit Vista commonly exposes this: an AnyCPU build will run as 64‑bit on Vista x64 but a CsGL native component is still 32‑bit, so the CLR fails while initializing the CsGL static/native layer.

Practical fixes (fastest first):

  • Force the app to run 32‑bit: set the Visual Studio project Build -> Platform target to x86 and rebuild. This is the simplest way to load 32‑bit native DLLs without changing libraries.
  • If a 64‑bit process is required, obtain or compile 64‑bit versions of the CsGL native/mixed assemblies and deploy those alongside the executable.

Verification and troubleshooting steps:

  • Confirm the bitness of the native DLLs (csgl or similar) with Dependency Walker (depends.exe) or dumpbin /headers and check the Machine field (x86 vs x64).
  • Use corflags on managed assemblies to inspect preference flags.
  • Ensure the native DLLs live in the application output folder; missing or wrong‑bit native binaries cause load-time failures.
  • Note that the OpenGL control creates its context during control creation/layout, so the crash will appear when the view is docked or the form lays out.

Additional notes: if matching architectures still fails, verify Vista x64 GPU drivers provide OpenGL support and consider switching to a maintained managed wrapper that provides explicit x64 binaries if CsGL lacks them.
