I have a WCF service hosted under IIS.
I have the following configuration:
<services>
<service name="BillboardServices.LoginService" behaviorConfiguration="LoginServiceBehavior">
<host>
<baseAddresses>
<add baseAddress="http://myip/LoginService/" />
</baseAddresses>
</host>
<endpoint address="" name="LoginService" binding="basicHttpBinding" contract="BillboardServices.ILoginService" />
<endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex" />
</service>
If I enter http://myip/LoginService/, I get a 404.
If I enter http://myip/Service1.svc, I get the service metadata.
What changes to the configuration do I need in order for the service to be accessible through the nice url?
Thank you.
In order to have and extensionless service, you need to use WCF 4 and init the routing engine in the global.asax file like so:
void Application_Start(object sender, EventArgs e)
{
RegisterRoutes();
}
private void RegisterRoutes()
{
// Edit the base address of Service1 by replacing the "Service1" string below
RouteTable.Routes.Add(new ServiceRoute("Service1", new WebServiceHostFactory(), typeof(Service1)));
}

Hello I'm having issue with my wcf service. I'm trying to call method which returns list of type object. I'm also using entity framework.
public IList<Product> GetAllProducts()
{
using (var db = new AuctionContext())
{
return db.Products.ToList();
}
}
</service>
<service name="AuctionSystem.WcfService.ProductService">
<endpoint address="" binding="wsDualHttpBinding" contract="AuctionSystem.WcfService.Contracts.IProductService">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="http://localhost:9993/Design_Time_Addresses/AuctionSystem.WcfService/ProductService/" />
</baseAddresses>
</host>
</service>
And contract :
[OperationContract]
IList<Product> GetAllProducts();
The method itself is working, but when I try to invoke this method on my wcf service UI it got stuck at "invoking service" I'm using wsdualhttpbinding.
Any ideas please?
EDIT: I realized in Product object I have virtual List, why is this List causing wcf to hang?
For all wondering why It was caused because of circular dependency.
I just spend 4 hours googling around trying to find why i cant consume (add service reference) WCF hosted in Windows service. Error i am getting is this
The URI prefix is not recognized.
Metadata contains a reference that cannot be resolved: 'net.tcp://localhost:8523/Service1'.
Could not connect to net.tcp://localhost:8523/Service1. The connection attempt lasted for a time span of 00:00:02.0158574. TCP error code 10061: No connection could be made because the target machine actively refused it 127.0.0.1:8523.
No connection could be made because the target machine actively refused it 127.0.0.1:8523
If the service is defined in the current solution, try building the solution and adding the service reference again.
I created a small service following this tutorial https://msdn.microsoft.com/en-us/library/ff649818.aspx to the letter. I'm stuck on step 8 where i get error i posted above.

Things I've tried so far:
Turning off windows firewall
Opening port TCP 8523 (in and outbound rules)
Changing port numbers
Checking netstat -atn (TCP port 8523 is not listnening)
Double checking that serviceProcessInstaller1 has account option set to Network service
Double checking that serviceInstaller1 has StartType option set to Automatic
Double checking that Service1 is Started in services.msc
Enabled all Net.XXX Services in services.msc
Remove then Added TCP Activation and TCP Port Sharing in "Turn windows features on or off"
Ran out of ideas
Any help as to why i can't consume WCF is highly appreciated.
I've recently implemented a CustomServiceHostFactory and am wondering how to debug it by hitting breakpoints in code. Here is the factory:
public class CustomHostFactory : ServiceHostFactory
{
protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
{
ServiceHost host = new ServiceHost(serviceType, baseAddresses);
//configure WsHttpBinding
ConfigureServiceThrottling(host);
return host;
}
private void ConfigureWshttpBinding(ServiceHost host)
{
//Do something here....
}
private void ConfigureServiceThrottling(ServiceHost host)
{
ServiceThrottlingBehavior throttle = host.Description.Behaviors.Find<ServiceThrottlingBehavior>();
if (throttle == null)
{
throttle = new ServiceThrottlingBehavior
{
MaxConcurrentCalls = 100,
MaxConcurrentSessions = 100,
MaxConcurrentInstances = 100
};
host.Description.Behaviors.Add(throttle);
}
}
}
I create this in an empty web project and here are the pertinent Web.config contents.
<service name="Company.Project.Business.Services.AccountService" behaviorConfiguration="MyServiceTypeBehaviors">
<endpoint address=""
binding="basicHttpBinding"
contract="Company.Project.Business.Contracts.Service.IAccountService"/>
<endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex" />
</service>
<service name="Company.Project.Business.Services.AccountClassService" behaviorConfiguration="MyServiceTypeBehaviors">
<endpoint address=""

<endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex" />
</service>
</services>
<serviceHostingEnvironment>

</serviceActivations>

I publish this to IIS and can successfully browse to and consume the services. Here is a path to one for example.
http://company.server.local/Project/Account/AccountService.svc
I am now trying to programmatically apply WsHttpBinding with open/close/send timeouts, readerQuotas, etc. I am trying to do this all in code and it would be helpful if I could step into the CustomeHostFactory to debug but have no idea how to do that. Any help is much appreciated. Thanks.
Ok, I was totally confused here. Instead of trying to attach to the w3wp process, I just set the project with the CustomHostFactory as the startup project in Visual Studio. I put a breakpoint in the protected override ServiceHost CreateServiceHost method.
Then, when I run the project http://localhost:58326/ comes up in a browser. I then had to actually browse to an endpoint like so: http://localhost:58326/Account/AccountService.svc in order to hit the breakpoint.
Now I can debug my programmatic configuration of the service. Hopefully this helps someone else.
I'm getting this
HTTP Error 404.0 - Not Found
The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.
when trying to access the service from my browser. Here is my config.
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<services>
<!-- Note: the service name must match the configuration name for the service implementation. -->
<service name="WcfServiceLibrary.Service1" behaviorConfiguration="MyServiceTypeBehaviors" >
<!-- Add the following endpoint. -->
<!-- Note: your service must have an http base address to add this endpoint. -->
<endpoint contract="WcfServiceLibrary.Service1" binding="basicHttpBinding" address="http://localhost/service1" />
<endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="http://localhost/service1/mex" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="MyServiceTypeBehaviors" >
<!-- Add the following element to your service behavior configuration. -->
<serviceMetadata httpGetEnabled="true" httpGetUrl="http://localhost/service1" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>
When I type http://localhost/service1 in the web browser I get the 404. But if I remove the app.config below and just simpley do this in the code behind
string serviceUrl = "http://localhost/service1";
Uri uri = new Uri(serviceUrl);
host = new ServiceHost(typeof(Service1), uri);
host.Open();
All works well... Any ideas? Seems simple enough.
I think you are missing the host element under your services:
<service name="WcfServiceLibrary2.Service1">
<host>
<baseAddresses>
<add baseAddress = "http://localhost/service1" />
</baseAddresses>
</host>
<endpoint address ="" binding="wsHttpBinding" contract="WcfServiceLibrary2.IService1">
<identity>
<dns value="localhost"/>
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>
Service host does not need URL then.
static void Main(string[] args)
{
var host = new ServiceHost(typeof(Service1));
host.Open();
Console.WriteLine("Host running");
Console.ReadLine();
}
You can show http://localhost/service1?Wsdl in the browser but mex only works with add service reference or WCFTestClient (C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE) because you will get the HTTP Bad Request error which comes from the fact that the browser issues an HTTP GET request where the contents of the message are in the HTTP headers, and the body is empty.
This is exactly what the WCF mexHttpBinding is complaining about.
I have two classes implementing a contract at a service which are consumed from a factory on the client like shown below.
[ServiceContract]
public interface MyInterface {
void DoSomething()
}
public class A : MyInterface {
public void DoSomething(){
"Hi I'm A"
}
}
public class B : MyInterface {
public void DoSomething(){
"Hi I'm B"
}
}
public class MyFactory <TMyInterface> {
void DoSomething(){
TMyInterface.DoSomething()
}
}
The client must remain the same. My question is how can I choose at the server side which implementation of MyInterface to use, by passing the type parameter using .config file in WCF
I read other post but I don't understand yet :(
It is possible to do it, and there are a few ways to do it.
One possibility is to create a "routing" service which will contain the "public" address which the client always talks to. This routing service can then, based on some configuration, redirect the call to the appropriate "real" service.
Another way is to actually have a process which starts both services, but their addresses are defined in config. If you use the same binding and the same contract (which is the case), then you can "flip-flop" the service address when you want to change the service which will receive the calls from the client. For example, this configuration directs the requests to the endpoint at "http://machine-name:8000/Service" to service A. Notice that, since you define service hosts for both services, you actually need to have a base address for service B as well - in this case I used named pipes, which cannot be accessed via different machines.
<system.serviceModel>
<services>
<service name="A">
<host>
<baseAddresses>
<add baseAddress="http://machine-name:8000/Service"/>
</baseAddresses>
</host>
<endpoint address="" binding="basicHttpBinding" contract="MyInterface" />
</service>
<service name="B">
<host>
<baseAddresses>
<add baseAddress="net.pipe://localhost/ServiceBackup"/>
</baseAddresses>
</host>
<endpoint address="" binding="netNamedPipeBinding" contract="MyInterface" />
</service>
</services>
</system.serviceModel>
when you want to change the address for B, you'd then swap the addresses.
<system.serviceModel>
<services>
<service name="A">
<host>
<baseAddresses>
<add baseAddress="net.pipe://localhost/ServiceBackup"/>
</baseAddresses>
</host>
<endpoint address="" binding="netNamedPipeBinding" contract="MyInterface" />
</service>
<service name="B">
<host>
<baseAddresses>
<add baseAddress="http://machine-name:8000/Service"/>
</baseAddresses>
</host>
<endpoint address="" binding="basicHttpBinding" contract="MyInterface" />
</service>
</services>
</system.serviceModel>
The hosting program would look like this:
public static void HostServices()
{
ServiceHost hostA = new ServiceHost(typeof(A));
ServiceHost hostB = new ServiceHost(typeof(B));
hostA.Open();
hostB.Open();
Console.WriteLine("Press ENTER to close");
Console.ReadLine();
hostA.Close();
hostB.Close();
}
Now, if your services are hosted in IIS (webhost), then it's a little harder. Since the "normal" activation requires a .svc file to be part of the endpoint address, and each .svc file is associated with a single class, the address for A would be something like http://machine-name/services/a.svc while the address for B would be something like http://machine-name/services/b.svc. So what you'd need to do in this case is to create a custom ServiceHostFactory, and use the ASP.NET Routes integration to create a .svc-less URL for your service. Then you'd use something similar to the previous example to decide which service will be activated.
