My colleagues on the WCF Data Services Team have announced OData T4 for C#.
If you are not already into OData – then you need to consider Odata your solution to simple exposing your data through a queriable service. - If you are not already into T4 – then you need to consider T4 your code generation solution, completely built into Visual Studio.
I’m very excited to announce the release of OData T4 for C# Preview 1, for the October 2011 CTP of the next version of WCF Data Services libraries, with support for code generation of service operations. The goal of this T4 preview and subsequent ones will be to get community feedback on the templates before having “Add Service Reference” natively generate T4 templates out of the box in a future release.
