I am trying to create Mainframe display from .Net desktop application. I have added RumbaRDEFactory.dll, however I am getting error like below,

Exception: Exception thrown: 'System.IO.FileNotFoundException' in RumbaRDEFactory.dll ("Could not load file or assembly 'RUMBAFramer, Version=1.3.0.0, Culture=neutral, PublicKeyToken=48204d95c48374bb' or one of its dependencies. The system cannot find the file specified."). Exception thrown: 'System.IO.FileNotFoundException' in RumbaRDEFactory.dll ("Could not load file or assembly 'RUMBAFramer, Version=1.3.0.0, Culture=neutral, PublicKeyToken=48204d95c48374bb' or one of its dependencies. The system cannot find the file specified.") 2.65s [15340] <No Name>

I have tried to manually refer RUMBAFramer dll, but still this error is shown. Could you please help here?

I have code like this to show mainframe display.

MainframeDisplay = new MFDisplayControl.MFDisplayControl();
_MainframeDisplay = MainframeDisplay.IMainframeDisplay;
_MFHostList = MainframeDisplay.IMainframeDisplay.TN3270HostsList;
_RDEConnection = MainframeDisplay.IRDEDisplay.IRDEConnection;

I am getting error on line #3 as IMainframeDisplay is null.
