I am building a WinForms app in Visual Studio 2010 Express which includes a number of class libraries I have built. The app is targeting the .net 4.0 Client Profile so no System.Web availability which is fine as I am not using it.
Other than the class libraries there are some service references. When I try to build the app it fails as the main class library apparently references System.Web. I have tried searching in Visual Studio for various strings such as "System.Web" and "HttpUtility" but nothing is found.
Is there a way to identify where the reference to System.Web occurs?
