For me, even after adding a link to a local copy of Microsoft.Web.Service3.dll, I still had to change the project for .NET 4.0 and not the .NET 4.0 Client .
Microsoft.Web.Service3.dll has a dependency on System.Web , which does not exist in the .NET 4.0 Client , but does so in .NET 4.0 .
This fact was noted in the list of errors in the warnings. Only that Microsoft.Web namescape could not be found was in Errors.
