I receive an error stating that the Microsoft.Expression.Drawing.dll and Microsoft.Expression.Effects.dll is missing and not found.

These assemblies are included in the installation directory of Open Automation Software and can be included as a Reference in your project as local copy.

Or you can install the Blend SDK from the following link that also includes these files.
