An exciting new set of features has become available which will help to expand reach of eXtreme Scale grids into a new pool of applications. Available today is the tech preview of the eXtreme Scale REST Data Services Framework, which creates an ADO.NET Data Services facade to an eXtreme Scale Data Grid. This access and query specification is based on REST, so the potential here is significant. Any client language or application with REST bindings can be modified to directly access an eXtreme Scale grid. Learn more at the following links, including documentation, downloads as well as a C# sample to show how this integrates with ADO.NET:
