Why invoking MWArray throws exception in my project

Hi, In my C# code, I am using MWStructArray and MWArray. The moment MWArray instance is created, I get the following error. I am using 64bit runtime on 64 bit windows 7 OS. My C# code is compiled for .net version 4 and x64 settings.

Please help

Managed Debugging Assistant 'BindingFailure' has detected a problem in 'C:\Projects\Production\SGUK\dotnet_projects\apps\StrategySystem\StrategyClient\bin\x64\Debug\StrategyClient.vshost.exe'. Additional Information: The assembly with display name 'MWArray' failed to load in the 'Load' binding context of the AppDomain with ID 1.

The system cannot find the file specified.
