Unable to execute a default project from microsoft.

At runtime, I get an error:

Could not load file or assembly 'Microsoft.Dynamics.Commerce.Runtime.FiscalIntegration.DocumentProvider.Messages, Version=7.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
