BadImageFormat exception because of just class definition.

Hi all! I have big experience in the unmanaged C++. And have almost no experience in all these NET things. So, I started a project using managed C++ yesterday. Looks, like it will put me to the grave... For the context. I'm writing a plugin for ClearCanvas application. My plugin already have some classes that are inherited from the classes in the ClearCanvas SDK. Plugin is loading and working well. Now imagine the situation. I define a new class that inherits the simple interface. The inheritance model is: IDisposable->IRenderingSurface->MyClass IRenderingSurface is just a simple interface that declares 4 properties without implementation of them. So I implement my class like this:

ref class VolumeRenderingSurface :
public ClearCanvas::ImageViewer::Rendering::IRenderingSurface
{
public:
// Constructor.
VolumeRenderingSurface(System::IntPtr windowID, int width, int height);
// Destructor
~VolumeRenderingSurface();

        /// Window ID property
        property System::IntPtr WindowID
        {
            virtual System::IntPtr get() {return m\_windowID;}
            virtual void set(System::IntPtr id) {m\_windowID = id;}
        }
        /// Context ID property
        property System::IntPtr ContextID
        {
            virtual System::IntPtr get() {return m\_contextID;}
            virtual void set(System::IntPtr id) {m\_contextID = id;}
        }
        /// Client rectangle property property
        property System::Drawing::Rectangle ClientRectangle
        {
            virtual System::Drawing::Rectangle get() {return m\_clientRectangle;}
            virtual void set(const System::Drawing::Rectangle rect) {m\_clientRectangle = rect;}
        }
        /// Clip rectangle property property
        property System::Drawing::Rectangle ClipRectangle
        {
            virtual System::Drawing::Rectangle get() {return m\_clipRectangle;}
            virtual void set(const System::Drawing::Rectangle rect) {m\_clipRectangle = rect;}
        }
    private:
        System::IntPtr m\_windowID;
        System::IntPtr m\_contextID;
        System::Drawing::Rectangle m\_clientRectangle;
        System::Drawing::Rectangle m\_clipRectangle;
    };

The constructor and destructor are defined but empty. I even DONT use this class anywhere, just define it.

Wow, I found a problem. Although this is my (no big) mistake, the result is just unexpected. virtual void set(const System::Drawing::Rectangle rect) {m_clientRectangle = rect;} Should be replaced with: virtual void set(System::Drawing::Rectangle rect) {m_clientRectangle = rect;} No const! Well I know const doesnt mean here anything. I've tried to use const reference from the very beginning. Then it failed to compile, I removed reference, but forgot to remove const. As a result - 5 hours wasted because of const that actualy doesnt mean anything! Fairy .NET :)
