Giving error "Unable to resolve referenced type"

[jasmakasana]

Hi,
In my project script# is giving following error.
C:\Program Files (x86)\ScriptSharp\v1.0\ScriptSharp.targets(36,5): error : Un
able to resolve referenced type . Make sure all needed assemblies have been explicitly referenced. [].
I have made sure that all the assemblies for the project are provided.

There are 3 projects :
1)Module.Contracts : which has only interfaces and a cs file with enums and constants.
2)Module : Has classes that are derived from interfaces.
3)Application

in this Module and Application are having ref. of Module.Contracts.
thnks.
