Problem of gluNewQuadric() in VS .Net?

Dear All,

I don’t know why every time I try to call
GLUquadricObj *pObj = gluNewQuadric(); in the RenderScene() or anywhere else, there is no compilation but an exception error when run which says "An unhandled exception of type ‘System.TypeLoadException’ occurred in wow_v1.exe

Additional information: Could not load type GLUquadric from assembly wow_v1, Version=, Culture=neutral, PublicKeyToken=null.


Do anyone know the reason? I really feel very confused…
