Expression Blend 4 connecting to a Oracle DB

Is it possible to connect to an Oracle database using Expression Blend 4 in a Silve开发者_StackOverflow中文版rlight application?

i think you can connect with oracle by wcf service as expression blend is not for connecting with db. it doesn't support normal ADO.NET objects like DataTable, DataSet, DataColumn, Database connection objects. the only way is wcf service
