Can some explain me the difference between Message Contract and DataContract .i'm new to wcf.. so please give the brief explanation or provide me some code snippets
View 3 RepliesI have a method in wcf which returns stream of custom object. I need to deserialize this stream at client side, but my custom class which is exposed as data contract is not visible through client proxy. When I add a dummy operation contract which returns the custome object I am able to get this custom class. I dont want to write this dummy method as there are many such custom classes.
Is there any way to expose data contract without writing any operation contract that returns or accepts data contract type object?
I have just created my first WCF service and by default it has a datacontract named "Composite type" in it. I tried adding another one but i can't see it in the client application. I have already done update web reference on my client.
Code of the data contract is below.
<ServiceContract()> _
Public Interface IDocumentService
<OperationContract()> _
<FaultContract(GetType(FaultException))> _
[Code]....
why the class named "MyFaultException" is not available on my client code.Imports System.Runtime.Serialization
<ServiceContract()> _
Public Interface IDocumentService
<OperationContract()> _
[code]...
I have a lot confusion on data contract .I think Data contract will create according to the Service contract and Data Base Table. For Example Let say i have service contract and i have three table product,order,customer
[ServiceContract]
public interface IMembersService
{
[OperationContract]
void insertProductDetails(clsProduct objProduct);
//What about the return type can we make it bool
[OperationContract]
List<clsProduct> getproductInfoByID(int id);
[OperationContract]
List<clsProduct> getproductInfo();
//========================================
[OperationContract]
void insertOrderDetails(clsOrder objOrder);
//What about the return type can we make it bool
[OperationContract]
List<clsOrder> getOrderInfoByID(int id);
[OperationContract]
List<clsOrder> getOrderInfo();
//========================================
[OperationContract]
void insertCustomerDetails(clsOrder objOrder);
//What about the return type can we make it bool
[OperationContract]
List<clsOrder> getCustomerInfoByID(int id);
[OperationContract]
List<clsOrder> getCustomerInfo();
}
For this case can i create three datacontact clsProduct,clsOrder,clsCustomer .i mean data contact depends on ther service contact and the table.
What is the best way to create a Contract that will consume multiple database records? The database records will have 20 fields and maximun of 1000 rows.

View 1 Repliesi am trying to call a webmethod from a webservice within a webpart-project and just cant instanciate the class within my webservice. CongressDataExternalSoapClient wsSAP = new CongressDataExternalSoapClient(); at this line i get the following error message: Could not find default endpoint element that references contract 'com.miltenyibiotec.webservice.congress.CongressDataExternalSoap' in the ServiceModel client configuration section. This might be because no configuration file was found for your application...
attention should be paid to "SoapClient" at the end of my Class-Name: "CongressDataExternal". VS cannot find the Web-Class CongressDataExternal. in other ASP.NET-Projects, its possible... but not here!!! so the only class i can see is the CongressDataExternalSoapClient. i can also see the interfaces CongressDataExternalSoap and CongressDataExternalSoapChannel. i have already added the needed entries to the webconfig:
<applicationSettings>
<Miltenyi.Complaints.Sharepoint.Properties.Settings>
<setting name="Miltenyi_Complaints_SharePoint_com_miltenyibiotec_webservice_congress_CongressDataExternal" serializeAs="String">

View 4 RepliesI have a WCF service which has 4 Operation contracts.
I have added a new contract and it gets the data from database and returns the result set.
I can access the new contract and the service get the correct result set. But while passing the result set to the client I get the error of The underlying connection was closed: The connection was closed unexpectedly.
What are the steps to follow after adding a new contract like new binding etc.
I'm kind of new to asp.net and am bad at translating stack traces. While workign on the above function in my web services I've seem to have run into a problem.

View 2 RepliesI added a service reference via the add service reference method. I can see all of its services in the intellisense but when I run the project and it executes the line where I instantiate the service : MyProjectName.ServiceReferenceName.IServiceReferenceClient
client = new MyProjectName.ServiceReferenceName.ServiceReferenceClient;it throws this error:Could not find default endpoint element that references contract 'ServiceReferenceName.IServiceReferenceClient' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.
I am developing WCF services with single Contract, but now i need to create multiple Contract & Class with multiple endpoints. My class hierarchy is as follows
Employee :IEmployee
{
}
User : IUser

}
I have 2 Interface IEmployee, IUser n 2 Class Employee, User. Creating different endpoints with same binding.
Service contract and operational contract in details.
Whether Service contract can be applied to class or only to the interface.
What are the advantage of the service contract and operational contract in addition.
I am having a wcf service that is throwing this error...here is my code:
this is the javascript calling
this._Proxy = function (serviceURL, serviceParam, dataType, type, data) {

this._Type = type == null || type == 'undefined' || type == '' ? defaultType : type;
this._Data = data;
this.Invoke = function () {
debugger;
$.ajax({
url: this._URL,
dataType: this._DataType,

success: function () {

View 1 RepliesI need to get message integrity by encrypting the data while dataflow between Service <-> client (by directional). Below are the details.
Development Environment: .net framework 4.0; Windows 7, IIS7, VS2010.
Production Environment: .net framework 4.0; Windows 2008, IIS7.
Business Requirement:
I have an WCF Service hosted in IIS7. There are multiple Windows Forms Application as clients to my service. Services will be consumed via internet.User, Role information are stored in SQL Server 2008 database. Need to Authenticate and Authorize requests agains the SQL Server database. Dataflow is bi-directional. Clients will write data to service. And also Service will serve data to clients Data transfered in wires must be encrypted, in both directions. My approch to solution:
Below is the configuration setting in Service web.config file.
<system.serviceModel> <bindings> <wsHttpBinding> <binding name="POCWsHttpBinding"> <security mode="Message"> <message clientCredentialType="UserName" negotiateServiceCredential="true" /> </security> </binding> </wsHttpBinding> </bindings> <services> <service behaviorConfiguration="POCServiceBehaviour" name="SecurityPOC.SecuredService"> <endpoint address="" binding="wsHttpBinding" bindingConfiguration="POCWsHttpBinding" name="POCwsHttpBindingEndPoint" contract="SecurityPOC.ISecuredService" /> </service> </services> <behaviors> <serviceBehaviors> <behavior name="POCServiceBehaviour"> <serviceMetadata httpGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="false" /> <serviceCredentials> <serviceCertificate findValue="CN=WCFServer" storeLocation="LocalMachine" storeName="My" x509FindType="FindBySubjectDistinguishedName" /><userNameAuthentication userNamePasswordValidationMode="Custom" customUserNamePasswordValidatorType="Common.MyCustomUsernamePasswordValidator, Common" /> </serviceCredentials> </behavior> </serviceBehaviors> </behaviors> <serviceHostingEnvironment multipleSiteBindingsEnabled="true" /> </system.serviceModel>
Questions & Assumptions:
My assumption is that, client certificate is used for authentication. I am not using Certificates at Client side, becuase my client authentication will be done using UserNameValitions against the Database.
Am I write? Using only Server side Certificate, with negotiateServiceCredential="true".
Is it required is install Server certificate on client machines in this case?
I am assuming Server Certificate details will be downloaded to client site during the first call..
<security mode="Message">,
Assuming this setting takes care about the message security/encryption using the Server certificate, in both directions. As per my requirement, message must encryped on wire while tranfer between Server to client and while Client to Server.
Am I write?
My Last question...How to ensure that messages are being encripted on both directions, from Testing point-of-view. I need to take test evidences out of it.
