  • Shared classes are build under VS2008 only but not under MSBuild.

    - by Vasiliy Borovyak
    We share our classes between silverlight 3.0 client and server as is it described here. Everything works fine under Visual Studio 2008 only. Using msbuild with following command line parameters: C:\Windows\Microsoft.NET\Framework\v3.5\msbuild.exe FoobarApplication.sln /t:Rebuild /p:Configuration=Release /p:Platform="Any CPU" we get following error: Class1.cs(28,54): error CS0234: The type or namespace name 'WcfService' does not exist in the namespace 'Company.FoobarApplication' (are you missing an assembly reference?) Service References\geoServiceReference1\Reference.cs(24,81): error CS0234: The type or namespace name 'WcfService' does not exist in the namespace 'Company.FoobarApplication' (are you missing an assembly reference?) Done Building Project "C:\work\bov-tmp\FoobarApplication\SilverlightClassLibrary3\SilverlightClassLibrary3.csproj" (Rebuild target(s)) -- FAILED. Done Building Project "C:\work\bov-tmp\FoobarApplication\FoobarApplication.sln" (Rebuild target(s)) -- FAILED. I found exactly the same question here. There are 4 workarounds there, I tried first 3 of them and those did not worked out. The 4-th workaround is not the acceptable solution. Any thoughts how to build the solution?

  • RIA Services for transmitting non DB object-graph

    - by Mike Gates
    I have been getting into RIA services because I thought it would simplify dealing with the services layer of web applications I wish to build. I see lots of examples out there showing how to create DomainService classes which expose and consume entities that have some kind of relational database backing, and therefore have foreign-key relationships. However, I would like to know how to expose and consume normal object graphs...objects that contain references to eachother but don't have foreign keys. For example, say I want a service operation called "GetFolderInformation(string pathToFolder)". I want this to return a custom object called "FolderInformation" structured with: - string Name - IEnumerable<FileInformation> Files I cannot get this to work because it seems that RIA wants to deal with entities that have foreign key relationships. Why? Why can't the serializer just see my object references and recreate that in the proxy on the other side? Data exists behind service layers that doesn't necessarily have foreign key relationships...like folder/file for example. EDIT: I realized I hadn't asked my question! My question is, is there a way to do what I am trying to do?

  • Accessing protected REST endpoint with JQuery

    - by Andy
    I have a site where members login to their account (FormsAuth). I would like to set up a RESTful service that I can access using jQuery. I would like to protect these services using the same FormsAuth. How would a third-party site be able to access these services? They would need to pass in the Principal/Identity to the service, right? I've only seen examples of Basic Authentication (which Twitter uses and jQuery supports). I'm very new to WCT/REST, so not sure how this should be done.

  • Why won't VS2010 RC use my existing types when I add a service reference?

    - by Johan Driessen
    I have a huge problem getting services references in VS2010 RC to use existing assemblies. Even though I have a class library with all the data contracts (classes marked with DataContract and properties with DataMember) that is shared between the service project and the consuming project (which is a class library), when I add a service reference, the data contracts are regenerated withing the service reference instead of using the existing types. When I was using VS2010 beta 2, this worked fine, and I have existing service references using the very same data contracts. But if I add a new service reference, or even update an old one, it won't use the existing types anymore. I have made a mini-test-solution, with one service, one data contract type and one console app as a consumer (all in the same solution), and there it seems to work, but that's no great comfort to me. Is there any way to see why it can't use the existing types? Edit to clearify. It works to generate the proxy classes with svcutil.exe, and point to the data contracts dll, like this: svcutil.exe http://localhost/MyService.svc /reference:[Path To DataContracts]\DataContracts.dll /n:*,MyProject.MyServiceReference /ct:System.Collections.Generic.List`1 The question is, what possible reason could there be for Visual Studio to generate its own datacontracts instead of using the existing ones even though the "reuse" checkbox is checked and the datacontracts assembly is referenced.

  • Potential for SQL injection here?

    - by Matt Greer
    This may be a really dumb question but I figure why not... I am using RIA Services with Entity Framework as the back end. I have some places in my app where I accept user input and directly ask RIA Services (and in turn EF and in turn my database) questions using their data. Do any of these layers help prevent security issues or should I scrub my data myself? For example, whenever a new user registers with the app, I call this method: [Query] public IEnumerable<EmailVerificationResult> VerifyUserWithEmailToken(string token) { using (UserService userService = new UserService()) { // token came straight from the user, am I in trouble here passing it directly into // my DomainService, should I verify the data here (or in UserService)? User user = userService.GetUserByEmailVerificationToken(token); ... } } (and whether I should be rolling my own user verification system is another issue altogether, we are in the process of adopting MS's membership framework. I'm more interested in sql injection and RIA services in general)

  • Complex relationship between tables in NHibernate

    - by Ilya Kogan
    Hi all, I'm writing a Fluent NHibernate mapping for a legacy Oracle database. The challenge is that the tables have composite primary keys. If I were at total freedom, I would redesign the relationships and auto-generate primary keys, but other applications must write to the same database and read from it, so I cannot do it. These are the two tables I'll focus on: Example data Trips table: 1, 10:00, 11:00 ... 1, 12:00, 15:00 ... 1, 16:00, 19:00 ... 2, 12:00, 13:00 ... 3, 9:00, 18:00 ... Faults table: 1, 13:00 ... 1, 23:00 ... 2, 12:30 ... In this case, vehicle 1 made three trips and has two faults. The first fault happened during the second trip, and the second fault happened while the vehicle was resting. Vehicle 2 had one trip, during which a fault happened. Constraints Trips of the same vehicle never overlap. So the tables have an optional one-to-many relationship, because every fault either happens during a trip or it doesn't. If I wanted to join them in SQL, I would write: select ... from Faults left outer join Trips on Faults.VehicleId = Trips.VehicleId and Faults.FaultTime between Trips.TripStartTime and Trips.TripEndTime and then I'd get a dataset where every fault appears exactly once (one-to-many as I said). Note that there is no Vehicles table, and I don't need one. But I did create a view that contains all VehicleIds from both tables, so I can use it as a junction table. What am I actually looking for? The tables are huge because they cover years of data, and every time I only need to fetch a range of a few hours. So I need a mapping and a criteria that will run something like the following SQL underneath: select ... from Faults left outer join Trips on Faults.VehicleId = Trips.VehicleId and Faults.FaultTime between Trips.TripStartTime and Trips.TripEndTime where Faults.FaultTime between :p0 and :p1 Do you have any ideas how to achieve it? Note 1: Currently the application shouldn't write to the database, so persistence is not a must, although if the mapping supports persistence, it may help at some point in the future. Note 2: I know it's a tough one, so if you give me a great answer, you will be properly rewarded :) Thank you for reading this long question, and now I only hope for the best :)

  • Nservicebus serization issue of derived types

    - by Tiju John
    Hi Guys, for the context setting, I am exchanging messages between my nServiceBus client and nSerivceBus server. its is the namespace xyz.Messages and and a class, Message : IMessage I have more messages that are in the other dlls, like xyz.Messages.Domain1, xyz.Messages.Domain2, xyz.Messages.Domain3. and messages that derive form that base message, Message. I have the endpoints defined as like : at client <UnicastBusConfig> <MessageEndpointMappings> <add Messages="xyz.Messages" Endpoint="xyzServerQueue" /> <add Messages="xyz.Messages.Domain1" Endpoint="xyzServerQueue" /> <add Messages="xyz.Messages.Domain2" Endpoint="xyzServerQueue" /> </MessageEndpointMappings> </UnicastBusConfig> at Server <UnicastBusConfig> <MessageEndpointMappings> <add Messages="xyz.Messages" Endpoint="xyzClientQueue" /> <add Messages="xyz.Messages.Domain1" Endpoint="xyzClientQueue" /> <add Messages="xyz.Messages.Domain2" Endpoint="xyzClientQueue" /> </MessageEndpointMappings> </UnicastBusConfig> and the bus initialized as IBus serviceBus = Configure.With() .SpringBuilder() .XmlSerializer() .MsmqTransport() .UnicastBus() .LoadMessageHandlers() .CreateBus() .Start(); now when i try sending instance of Message type or any type derived types of Message, it successfully sends the message over and at the server, i get the proper type. eg. Message message= new Message(); Bus.Send(message); // works fine, transfers Message type message = new MessageDerived1(); Bus.Send(message); // works fine, transfers MessageDerived1 type message = new MessageDerived2(); Bus.Send(message); // works fine, transfers MessageDerived2 type My problem arises when any type, say MessageDerived1, contains a member variable of type Message, and when i assign it to a derived type, the type is not properly transferred over the wire. It transfers only as Message type, not the derived type. public class MessageDerived2 : Message { public Message message; } MessageDerived2 messageDerived2= new MessageDerived2(); messageDerived2.message = new MessageDerived1(); message = messageDerived2; Bus.Send(message); // incorrect behaviour, transfers MessageDerived2 correctly, but looses type of MessageDerived2.Message (it deserializes as Message type, instead of MessageDerived1) any help is strongly appreciated. Thanks TJ

  • Running an existing LINQ query against a dynamic object (DataTable like)

    - by TomTom
    Hello, I am working on a generic OData provider to go against a custom data provider that we have here. Thsi is fully dynamic in that I query the data provider for the table it knows. I have a basic storage structure in place so far based on the OData sample code. My problem is: OData supports queries and expects me to hand in an IQueryable implementation. On the lowe rside, I dont have any query support. Not a joke - the provider returns tables and the WHERE clause is not supported. Performance is not an issue here - the tables are small. It is ok to sort them in the OData provider. My main problem is this. I submit a SQL statement to get out the data of a table. The result is some sort of ADO.NET data reader here. I need to expose an IQueryable implementation for this data to potentially allow later filtering. Any ide ahow to best touch that? .NET 3.5 only (no 4.0 planned for some time). I was seriously thinking of creating dynamic DTO classes for every table (emitting bytecode) so I can use standard LINQ. Right now I am using a dictionary per entry (not too efficient) but I see no real way to filter / sort based on them.

  • Duplex communication using NetTcpBinding - ContractFilter mismatch?

    - by Shaul
    I'm making slow and steady progress towards having a duplex communication channel open between a client and a server, using NetTcpBinding. (FYI, you can observe my newbie progress here and here!) I'm now at the stage where I have successfully connected to my server, through the server's firewall, and the client can make requests of the server. In the other direction, however, things aren't quite so happy. It works fine when testing on my own machine, but when testing over the internet, when I try to initiate a callback from the server side, I get an error: The message with Action 'http://MyWebService/IWebService/HelloWorld' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver. Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None). Here are some of the key bits of code. First, the web interface: [ServiceContract(Namespace = "http://MyWebService", SessionMode = SessionMode.Required, CallbackContract = typeof(ISiteServiceExternal))] public interface IWebService { [OperationContract] void Register(long customerID); } public interface ISiteServiceExternal { [OperationContract] string HelloWorld(); } Then, on the client side (I was fiddling with these attributes without really knowing what I'm doing): [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession, Namespace="http://MyWebService")] class SiteServer : IWebServiceCallback { string IWebServiceCallback.HelloWorld() { return "Hello World!"; } ... } So what am I doing wrong here? EDIT: Adding app.config code. From server: <system.serviceModel> <diagnostics> <messageLogging logMalformedMessages="true" logMessagesAtServiceLevel="true" logMessagesAtTransportLevel="true" logEntireMessage="true" maxMessagesToLog="1000" maxSizeOfMessageToLog="524288" /> </diagnostics> <behaviors> <serviceBehaviors> <behavior name="mex"> <serviceDebug includeExceptionDetailInFaults="true"/> <serviceMetadata/> </behavior> </serviceBehaviors> </behaviors> <services> <service name ="MyWebService.WebService" behaviorConfiguration="mex"> <endpoint address="net.tcp://localhost:8000" binding="netTcpBinding" contract="MyWebService.IWebService" bindingConfiguration="TestBinding" name="MyEndPoint"></endpoint> <endpoint address ="mex" binding="mexTcpBinding" name="MEX" contract="IMetadataExchange"/> <host> <baseAddresses> <add baseAddress="net.tcp://localhost:8000"/> </baseAddresses> </host> </service> </services> <bindings> <netTcpBinding> <binding name="TestBinding" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" portSharingEnabled="false"> <readerQuotas maxDepth="32" maxStringContentLength ="8192" maxArrayLength ="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384"/> <security mode="None"/> </binding> </netTcpBinding> </bindings> </system.serviceModel> and on the client side: <system.serviceModel> <bindings> <netTcpBinding> <binding name="MyEndPoint" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions" hostNameComparisonMode="StrongWildcard" listenBacklog="10" maxBufferPoolSize="524288" maxBufferSize="65536" maxConnections="10" maxReceivedMessageSize="65536"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" /> <security mode="None"> <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign"> <extendedProtectionPolicy policyEnforcement="Never" /> </transport> <message clientCredentialType="Windows" /> </security> </binding> </netTcpBinding> </bindings> <client> <endpoint address="net.tcp://mydomain.gotdns.com:8000/" binding="netTcpBinding" bindingConfiguration="MyEndPoint" contract="IWebService" name="MyEndPoint" /> </client> </system.serviceModel>

  • Send A DataSet via Sockets in .NET

    - by FinancialRadDeveloper
    I had written a Web Service to return a DataSet back to my ASP.Net site and this was working fine. However due to security issues and also the ability to get certain references installed, I have to move this to an App Server and so doing it as a Windows Service and communicating with the ASP.Net site now via sockets. Is there a way I can easily give the Website a serialized DataSet via Sockets from my App Server so I can read this in and then just carry on using the code I currently have to bind this to a GridView?

  • What's the best way to reference a .DLL - as a normal reference or as a web service?

    - by dotnetdev
    Hi, What is the best way to reference an existing .NET dll (Class library)? Is there any benefit to expose web services from the class library and reference these as opposed to referencing the actual .dll (Although one benefit of the web service approach is the granularity and thus surface area exposed is up to you at coding time)? I am thinking with loose coupling in mind, as a criteria. Thanks

  • Deserialization on client side in Domain Service

    - by ankit
    I have 2 classes: Person and Contact. Person class has a property named ContactNumber which returns the Contact type, and this property is marked as a DataMember for serialization. I have marked Contact type as a DataContract. On the client side I am able to get the values, but when I try to insert a value and then do submit, I get the following exception: Failed to deserialize change-set. Failed to convert value of type 'Dictionary`2' to type 'Contact' Stack Trace is: at System.Web.Ria.DataServiceSubmitRequest.GetChangeSet(DomainService domainService) at System.Web.Ria.DataServiceSubmitRequest.Invoke(DomainService domainService) at System.Web.Ria.DataService.System.Web.IHttpHandler.ProcessRequest(HttpContext context) Can anyone give me the solution ?

    I have a service running under Local system account. I have an application that run in a non-UAC mode. Both interact with each other as both act as server and client. Application as client can communicate with Service. But Service as client cannot communicate with application. If I run with UAC the problem is solved. <customBinding> <binding name="net.pipe"> <namedPipeTransport /> </binding> </customBinding>

  • How to implement a lazy loaded Silverlight data grid without using paging

    - by Marc Wittke
    Using the Business Application template from the brand new released RIA Services, you can see lots of examples using the data grid on top of a DomainDataSource in combination with a DataPager. The properties PageSize and LoadSize can be used to adjust the amount of data to be displayed in one page and the data that is prefetched in the background. Now I'd like to have a data grid with a scrollbar and no pager. The underlying DomainDataSource should load only the data that is diplayed in the grid. It should trigger another load, when the user scrolls down to items that are not yet in the data context. Is there any sample implementation how to do this?
