I am developing an application with C # in the monodevelop, everything was going fine, even when I having extend the Form class and I get the following error:
/Volumes/Recover/Developer/WebCamTestA/WebCamTestA/VideoControl.cs (44,44): Error CS0012: The type System.ComponentModel.ISynchronizeInvoke 'is defined in an assembly that is not referenced. Consider adding a reference to assembly System, Version = 4.0.0.0, Culture = neutral, PublicKeyToken = b77a5c561934e089 '(CS0012) (WebCamTestA)
I have already imported all the dependencies needed to work with Windows.Form, but I still continue with the error.
