Can you double check that you are referencing this assembly. It is containing the new data services implementation that we have provided in the last release. However this assembly has always been built targeting the .NET 4.0 framework.
Which framework is the project referencing this one build against? Are you actually using anything that is in this assembly, and if not can you remove the reference to it.
I am looking forward to resolving this issue.
