I am trying to host a service using UDP in WCF but I can't generate a proxy from the service. I need to host the service on a LAN. Can anyone give an example for a server and client using UDP in WCF?
Here is my app.config file:
<?xml version="1.0" encoding="utf-8"?>

I've been looking online but I can't find a defined procedure or an example on how to configure a basicHTTP self-hosted WCF service to compress messages that servers sends to clients.
I would like to use GZIP or similar technology.
this is my application app.config:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.serviceModel>
<services>
<service name="Application.ApplicationServicesProxy" behaviorConfiguration="ApplicationSvcsBehave">
<host>
<baseAddresses>
<add baseAddress="http://localhost:9001/ApplicationSvcs"/>
</baseAddresses>
</host>
<endpoint address="http://localhost:9001/ApplicationSvcs" binding="basicHttpBinding" contract="Application.IApplicationServices"/>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="ApplicationSvcsBehave">
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="True"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.8"/>
</startup>
</configuration>
This is how I create the service:
var host = new ServiceHost(typeof(ApplicationServicesProxy));
host.Open();
Services are defined in IApplicationServices that is inherited by ApplicationServicesProxy
[ServiceContract]
interface IApplicationServices
{
[OperationContract]
string[] MethodOne();
}
public class AppicationServicesProxy : IApplicationServices
{
public string[] MethodOne()
{
// return a string value;
}
}
And this is how I connect the client to the service
var ApplicationSvcs = new ApplicationSvcs.ApplicationServicesClient("BasicHttpBinding_IApplicationServices");
I am currently using .NET 4.8
I solved doing like this, message size went down fromm 300 Kb/s to 11 Kb/s so it really works and CPU is not very interested in that:
<system.serviceModel>
<services>
<service name="Application.ApplicationServicesProxy" behaviorConfiguration="ApplicationSvcsBehave">
<host>
<baseAddresses>
<add baseAddress="http://localhost:9001/ApplicationSvcs"/>
</baseAddresses>
</host>
<endpoint address="" binding="customBinding" bindingConfiguration="BinaryCompressionBinding" contract="Application.IApplicationServices"/>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="ApplicationSvcsBehave">
<serviceMetadata httpGetEnabled="false" httpsGetEnabled="false" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
<bindings>
<customBinding>
<binding name="BinaryCompressionBinding">
<binaryMessageEncoding compressionFormat ="GZip"/>
<httpTransport decompressionEnabled="true"/>
</binding>
</customBinding>
</bindings>
</system.serviceModel>
and on client side
<system.serviceModel>
<bindings>
<customBinding>
<binding name="CustomBinding_IApplicationServices" >
<binaryMessageEncoding compressionFormat="GZip"/>
<httpTransport maxReceivedMessageSize="20000000"/>
</binding>
</customBinding>
</bindings>
<client>
<endpoint address="http://localhost:9001/ApplicationSvcs" binding="customBinding"
bindingConfiguration="CustomBinding_IApplicationServices" contract="ApplicationSvcs.IApplicationServices"
name="CustomBinding_IApplicationServices" />
</client>
</system.serviceModel>
SOAP messages can be very heavy but in my application I could not use REST so I hope that can be of any help.
I have created a wcf service, and want to run on secure way(https)
App.config
<?xml version="1.0" encoding="utf-8" ?>
<configuration>

<add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
</appSettings>
<system.web>

<baseAddresses>
<add baseAddress = "http://localhost:8734/Service1/" />
</baseAddresses>
</host>
<endpoint address="" binding="basicHttpBinding" contract="WcfServiceLibrary1.IService1">

</behaviors>
</system.serviceModel>
</configuration>
I have tried to change the base address from http to https.
And I have created self sign certificate from IIS and bind it with https with port 8374
Try with that configuration. I have changed the binding from BasicHttpBinding to BasicHttpsBinding and added "serviceCredentials" section where you have to select your certificate from some store on your machine.
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
</appSettings>
<system.web>
<compilation debug="true" />
</system.web>
<system.serviceModel>
<services>
<service name="WcfServiceLibrary1.Service1" behaviorConfiguration="MyServiceTypeBehaviors">
<endpoint address="" binding="basicHttpsBinding" contract="WcfServiceLibrary1.IService1"/>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="MyServiceTypeBehaviors">
<serviceCredentials>
<serviceCertificate findValue="" storeLocation="LocalMachine" x509FindType="FindByThumbprint" storeName="My"/>
</serviceCredentials>
<serviceMetadata httpGetEnabled="True" httpsGetEnabled="True"/>
<serviceDebug includeExceptionDetailInFaults="False" />
</behavior>
</serviceBehaviors>
</behaviors>
<protocolMapping>
<add binding="basicHttpsBinding" scheme="https"/>
</protocolMapping>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>
</system.serviceModel>
</configuration>
P.S. If the web service is hosted in IIS then you don't need baseAddress and port. Port Binding is done from the IIS Manager
I´m trying to implement a Wcf Duplex Service in my Windows Store Application. In my .NET WPF Application everything works fine. I use a NetTcpBinding.
Here is my Service Config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
<system.serviceModel>
<bindings>
<netTcpBinding>
<binding name="myNetTcpBinding" receiveTimeout="00:30:00">
<reliableSession enabled="true" inactivityTimeout="24.20:31:23"/>
</binding>
</netTcpBinding>
</bindings>
<services>
<service name="CnS.Base.Services.MessageHub.MessageHubService">
<endpoint address="" binding="netTcpBinding" bindingConfiguration="myNetTcpBinding" contract="CnS.Base.Services.MessageHub.IMessageHubService">
<identity>
<dns value="localhost"/>
</identity>
</endpoint>
<endpoint address="mex" binding="mexTcpBinding" bindingConfiguration="" contract="IMetadataExchange"/>
<host>
<baseAddresses>
<add baseAddress = "net.tcp://localhost:8655/MessageHubService" />
</baseAddresses>
</host>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="False" httpsGetEnabled="False"/>
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>
If i call a Method from the WCF Service i get a ActionNotSupportedException.I figured out that if i set
<reliableSession enabled=false"/>
It works fine. But my Problem is now that the Wcf connection is closed to my Windows Store App and i can´t Push Messages to this client.
Does anyone know a workaround for this Problem?
I have one wcf service on this site http://wswob.somee.com/wobservice.svc
I try to consume that service with my winform app. This is the error I receive when I create an instant of the service
com.somee.wobservice.IwobserviceClient myservice = new com.somee.wobservice.IwobserviceClient();
error:
Could not find default endpoint element that references contract
'com.somee.wobservice.Iwobservice' 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 searched and modified my app.config file:
<system.serviceModel>
<behaviors>
<endpointBehaviors>
<behavior name="wobservice">
<clientVia />
</behavior>
</endpointBehaviors>
</behaviors>
<client>
<endpoint
name="wobservice"
address="http://wswob.somee.com/wobservice.svc"
binding="webHttpBinding"
contract="com.somee.wobservice"
behaviorConfiguration="wobservice" />
</client>
</system.serviceModel>
</configuration>
And my web.config in wcf folder:
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>

<bindings>

<binding>
<security mode="None" />
</binding>
</webHttpBinding>
</bindings>
<protocolMapping>

<services>
<service name="wobwcf.wobservice">

behaviorConfiguration="Web"

</service>
</services>
</system.serviceModel>
I don't really sure which part I got wrong. My experience of wcf is just a week...
Copy system.serviceModel section from the app.config in your library project and put it in your web.config and refresh service reference. See also this answer. Could not find default endpoint element
Add "WSHttpBinding" end point in your WCF service web.config file like below
<endpoint address="web" behaviorConfiguration="jsonBehavior" binding="webHttpBinding" bindingConfiguration="webHttpBindingWithJsonP" contract="DataService.IDataService"/>
<endpoint address="" binding="wsHttpBinding" bindingConfiguration="wsHttpBinding" contract="DataService.IDataService" />
and in your app.config file write code like below
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="WSHttpBinding_IDataService" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647">
<security mode="None" />
</binding>
</wsHttpBinding>
</bindings>
<client>
<endpoint address="http://localhost/pricedataservice/DataService.svc" binding="wsHttpBinding"
bindingConfiguration="WSHttpBinding_IDataService" contract="DataService.IDataService"
name="WSHttpBinding_IDataService" />
</client>
I am sure this will fix your problem and below blog will help you to understand different type of binding in WCF service
http://www.dotnet-tricks.com/Tutorial/wcf/VE8a200713-Understanding-various-types-of-WCF-bindings.html
Add client definition in your client web.config file like below;
<system.serviceModel>
/////
<client>
<endpoint address="referencedurl"
binding="webHttpBinding" bindingConfiguration=""
contract="MemberService.IMemberService"
name="MemberServiceEndPoint"
behaviorConfiguration="Web">
</endpoint>
</client>
////
</system.serviceModel>
AND Service Reference Name must same as the Interfaces prefix. contract="ReferenceName.IMemberService"
I developed a WCF in a Managed Windows Service, based on this tutorial
This is how my interface are defined :
namespace HomeAutomationWindowsService
{
[ServiceContract]
public interface IHomeAutomation
{
[OperationContract]
string connect();
[OperationContract]
Boolean sendAction(string address, string command);
}
}
And my App.config file is like this :
<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web>
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="Unsecured">
<security mode="None" />
</binding>
</wsHttpBinding>
</bindings>
<services>
<service name="HomeAutomationWindowsService.HomeAutomationService"
behaviorConfiguration="HomeAutomationServiceBehavior">
<host>
<baseAddresses>
<add baseAddress="http://192.168.11.178:8000/service"/>
</baseAddresses>
</host>
<!-- this endpoint is exposed at the base address provided by host: http://localhost:8000/service -->
<endpoint address=""
contract="HomeAutomationWindowsService.IHomeAutomation"
binding="wsHttpBinding"
bindingConfiguration="Unsecured" />
<!-- the mex endpoint is explosed at http://192.168.11.178:8000/ mex -->
<endpoint address="mex"
binding="mexHttpBinding"
contract="IMetadataExchange" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="HomeAutomationServiceBehavior">
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="False"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
When I make a call from a Console or a WPF App I can see the public methods, but when I do it using Windows Phone I can't see anything.
What I should do to make my WCF or Windows Phone communicating together.
I think WsHttpBinding is not supported by WP7. Try using BasicHttpBinding:
Web.config:
<system.serviceModel>
<services>
<service name="MyProject.MyService" behaviorConfiguration="behavior">
<endpoint address="" binding="basicHttpBinding" bindingConfiguration="binding" contract="MyProject.MyService" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="behavior">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
<bindings>
<basicHttpBinding>
<binding name="binding">
</binding>
</basicHttpBinding>
</bindings>
</system.serviceModel>
After adding the webservice to your WP7 project (add service reference) the ServiceReferences.ClientConfig should look like (adding web service with WsHttpBinding generates an empty file):
<configuration>
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_DataService" maxBufferSize="2147483647"
maxReceivedMessageSize="2147483647">
</basicHttpBinding>
</bindings>
<client>
<endpoint address="https://localhost:44300/Services/DataService.svc"
binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_DataService"
contract="DataService.DataService" name="BasicHttpBinding_DataService" />
</client>
</system.serviceModel>
</configuration>
