How can I detect managed memory leak in a c# code? It's about a windowsform application using openGL for rendering 3D objects. Each time I redraw a memory leak is happening.

Base on the analysis done with DebugDiag tool , "C:\Windows\System32\ig75icd32.dll" is the source of memory leak.
Is this a bug in openGL or my code? How can I fix this issue?

I found the memory leek source. It was because of opneGL lists.
In a part of my code, I had this code for each 3D object

 void UpdateList(){
   _List = Gl.glGenLists(1);
   Gl.glNewList(_List, Gl.GL_COMPILE);
   Polygons.Draw();
   Gl.glEndList();
Which was in a loop (object's list updating in loop). So many lists were generated for each 3D object and there was many alive objects. I changed the code like this
void UpdateList(){
   if(_List==-1)
       _List = Gl.glGenLists(1);
   Gl.glNewList(_List, Gl.GL_COMPILE);
   Polygons.Draw();
   Gl.glEndList();
So only one list handel is generated for each 3D object.
