Recently I am trying to port one of my WinForm Application to MONO , I have
used MS DirectShow.NET quite extensively in the project. I did do a
compatibility test on the DirectShowLib2005.dll and found that more or less
all the methods and props is MONO Compatible.


However when I try running the pllication on MONO I get the following error


System.DllNotFoundException: ole32.dll

  at (wrapper managed-to-native) System.__ComObject:CoInitialize (intptr)

  at System.__ComObject..ctor () [0x00000]

  at System.Windows.Forms.NativeWindow.WndProc (IntPtr hWnd, Msg msg, IntPtr
wParam, IntPtr lParam) [0x00000]


I am at a loss as I do not have any prior knowledge on working on this
