问题 I've written a WCF Data Service that is self hosted in a Windows console application. The service is initialised with the following code: static void Main(string[] args) { DataServiceHost host; Uri[] BaseAddresses = new Uri[] { new Uri("http://12.34.56.78:9999")}; using (host = new DataServiceHost( typeof( MyServerService ), BaseAddresses ) ) { host.Open(); Console.ReadLine(); } } When I run this, the console app runs and appears to listen on 0.0.0.0:9999 and not 12.34.56.78:9999.

问题 I have a Wcf Data service exposing entities from Ado.net entity framework. I would like to know whethere I can use msmq messaging with my data service. After searching on internet i could find links for using with a wcf service only. Please provide some links with a sample. 回答1: No you cannot.

问题 I am trying to authenticate calls to a WCF DataServices service via Silverlight. Essentially, when a user logs in they get a special hash which should be embedded in the headers of every request to the WCF DataServices. Currently use this as a check via a QueryInterceptor method eg [QueryInterceptor("Orders")] public Expression<Func<Orders,bool>> OnQueryOrders() { string hash = WebOperationContext.Current.IncomingRequest.Headers.Get("MyHeader"); if(!TestHash(hash)) { return o => false; } else

问题 I am trying to write REST web service through which our clients can upload a file on our file server. IS there an example or any useful links which I can refer for any guidance? I haven't seen many examples of POST operation using ADO.NET data services available. 回答1: I've uploaded a file to ADO.NET dataservices using POST although I'm not sure whether it's the recommended approach.
