no instance of constructor matches the argument list

Hello,

I have 3 files: <code>beans</code>

Window.h has declarations for a class named WindowClass:

class WindowClass
{
public:
	WindowClass(UINT Style,
		HINSTANCE hInstance,
		HICON Icon, HCURSOR Cursor,
		HBRUSH Background, LPCTSTR MenuName,
		LPCTSTR className, HICON IconSm);
	~WindowClass();
	bool Register();
private:
	WNDCLASSEX m_wc;
};

Window.cpp has definitions for the class WindowClass:

WindowClass::WindowClass(UINT Style,
	HINSTANCE hInstance,
	HICON Icon, HCURSOR Cursor,
	HBRUSH Background, LPCTSTR MenuName,
	LPCTSTR className, HICON IconSm)
{
	m_wc.cbSize = sizeof(WNDCLASSEX);
	m_wc.style = Style;
	m_wc.lpfnWndProc = DefWindowProc;
	m_wc.cbClsExtra = 0;
	m_wc.cbWndExtra = 0;
	m_wc.hInstance = hInstance;
	m_wc.hIcon = Icon;
	m_wc.hCursor = Cursor;
	m_wc.hbrBackground = Background;
	m_wc.lpszMenuName = MenuName;
	m_wc.lpszClassName = className;
	m_wc.hIconSm = IconSm;
}
WindowClass::~WindowClass()
{
}
bool WindowClass::Register()
{
	return RegisterClassEx(&m_wc);
}

WinMain.cpp is the window initializer:

int WINAPI wWinMain(HINSTANCE MainInstance, HINSTANCE hPrevInstance, PWSTR pCmdLine, int nCmdShow)
{
WindowClass MainWndClass(NULL, MainInstance,
LoadIcon(MainInstance, IDI_APPLICATION),
LoadCursor(MainInstance, IDC_ARROW),
NULL, NULL,
"Main Window Class",
LoadIcon(MainInstance, IDI_APPLICATION));
Window MainWindow;
}

however, i'm getting this error:
