For those who are using LINQ to call the data services from Project Nimbus, for your information, there is an issue with the .Net Framework client as well as the ADO.NET Data Services.
In the previous post, we showed you how you can use ADO.NET Data Services using LINQ which can fasten your coding process. This scenario will work if ONLY you are using Visual Studio 2008 and have downloaded the ADO.NET Data Services v1.5 CTP 2.
However, if you are using Visual Studio 2010, ADO.NET Data Services is already in built in Visual Studio 2010. Hence, you will not need to download the installer in this case. If you are using Visual Studio 2010 with LINQ, you got to use .NET Framework 4.0 instead. Using a .NET Framework 3.5 will result in a “NotSupportedException” error. This is likely due to the different ADO.NET Data Services version used in Visual Studio 2008, .Net Framework 3.5 and Visual Studio 2010, .Net Framework 4.0.

Hi
Thanks for all these effort and tips!
Are the data free or are there licensing requirements?
Thanks!

Hi Peter,
All the datasets offered for now would be free of charge.
If in any case if in near future, any providers are thinking of charging, we would negotiate to drive a freemium model as much as possible.
Do drop us another comment or email if you have any more queries.
