I have a WCF service hosted by a simple WinForms app. In Visual Studio the service is started via the built in WCF Service Host & everything works fine. I now want to host the service in my host app but currently the service doesn't run.
Service App:
ServiceHost host;
private void btnStart_Click(object sender, EventArgs e)
{
host = new ServiceHost(typeof(RegimesService));
host.Open();
lblStatus.Text = "Started...";
}
If I close WCF Service Host in the sys tray & click my start button, the code runs but the service never starts?
Here's my Service Host App config:
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="metaBehavior">
<serviceMetadata httpGetEnabled="true" />
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service name="diiRegimesService.RegimesService">
<endpoint address="" binding="basicHttpBinding" contract="diiRegimesService.IRegimesService"/>
<host>
<baseAddresses>
<add baseAddress="http://localhost:8081" />
</baseAddresses>
</host>
</service>
</services>
</system.serviceModel>
& Finally my Service project App.config:
<system.serviceModel>
<services>
<service name="diiRegimesService.RegimesService">
<endpoint address="" binding="basicHttpBinding" contract="diiRegimesService.IRegimesService">

When I run netstat -a from cmd line, the port http://localhost:8080 isn't listening so it's like the service object never actually gets initialized. I'm sure it's a simple mistake in my configs somewhere, any ideas? Thanks
Port 8080 is a reserved port for SQL Server, Also your service App.config and Host App.config are having different ports in their base address
Ok, used the WCF configuration wizard from Solution Explorer & tied the ServiceBehaviour to the Service definition in the Host App's App.Config & hey presto, everything is wired up & working! Thanks for your help #Akshay Choudhary.

My problem is that if I have my website using https:// it fails to make the http call because of CORS. The https website makes an ajax GET request to the localhost.
Now I am trying to change my windows service to https but everywhere I see some command line ssl bindings. Is there a different way I can change my wcf self hosted windows service to use https?
What do I need to do in order to get this http service migrated over to https.
Please provide example of what needs to be modified in my app.config.
I stumbled upon similar problem so what i did was used WCF Configuration tool to write a App.Config for me and inside endpoints I selected mexhttpsbinding and yaa the https binding worked..
Let's just add an https endpoint. The following configuration works properly over both http and https.
<system.serviceModel>
<services>
<service behaviorConfiguration="mybehavior" name="WcfService1.Service1">
<endpoint address="" binding="webHttpBinding" contract="WcfService1.IService1" behaviorConfiguration="webbev"></endpoint>
<endpoint address="" binding="webHttpBinding" contract="WcfService1.IService1" behaviorConfiguration="webbev" bindingConfiguration="myhttpsbinding"></endpoint>
<endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange"></endpoint>
<host>
<baseAddresses>
<add baseAddress="http://localhost:11010"/>

Since https protocol is protected by the certificate, we are supposed to bind the certificate to the https port for https endpoint. (we could specify the certificate in IIS binding module instead of CMD if hosting the service in IIS)
netsh http add sslcert ipport=0.0.0.0:11011 certhash=0000000000003ed9cd0c315bbb6dc1c08da5e6 appid={00112233-4455-6677-8899-AABBCCDDEEFF}
Execute CMD with administrator privileges and ensure that the certificate is installed on the local machine certificate store (certlm.msc). Certhash parameter specifies the thumbprint of the certificate. The appid parameter is a GUID that can be used to identify the owning application(located in the project.csproj file)

Feel free to contact me if there is anything I can help with.
Https only works on port 443. so you better have your virtual host created in your SSL script tag in your server configuration.
Or you can also proxy pass your request http:// port(8888) to https:// (port:443)
I had developed a windows service that hosts a WCF service. The service is installed on a server and the idea is to process some files on the local network (domain). Also, the service is executing as my domain user.
the configuration of the service is this:
<system.serviceModel>
<services>
<service name="Zeus.My.Upload.Service.MyHostedService">
<host>
<baseAddresses>
<add baseAddress="http://localhost:1089/Domain/Service"/>
</baseAddresses>
</host>
<endpoint address="http://localhost:1089/Domain/Service/Uploader" binding="basicHttpBinding" contract="Zeus.My.Upload.Contract.IHostedService" />
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>
</services>
<bindings>
<basicHttpBinding>
<binding maxReceivedMessageSize="4294967296" transferMode="Streamed" sendTimeout="01:00:00" messageEncoding="Mtom">
<security mode="None">
</security>
</binding>
</basicHttpBinding>
</bindings>
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
The issue with this configuration is that only my user is able to access and use this service. Other users of domain cannot even access to the URL.
How can I solve this issue?
I created a simple WCF service and hosted it in IIS by creating a new website. In Web.config file,I am providing bindings for http and net tcp.
I created a console client and adding service reference. It generates two binding in client config - for http and for tcp. When I try to invoke the service using tcp, I get this error -
An unhandled exception of type 'System.ServiceModel.EndpointNotFoundException' occurred in mscorlib.dll
Additional information: There was no endpoint listening at net.tcp://computername/Service.svc that could accept the message. This is often caused by an incorrect address or SOAP action.
when I run using Http endpoint , it works fine.
Note -
I am using Windows 10 OS, IIS 10.0 and WPAS\WAS (Windows Process Activation Service) are installed. I already enabled\checked HTTP Activation, TCP Activation in .Net framework in Windows features. And modified IIS server settings to include net tcp. Please check it in attached image.
My website Web.config file looks like
<system.serviceModel>
<bindings>
<netTcpBinding>
<binding name="NewBinding0" portSharingEnabled="true">

Following this guide i try to Host WCF service in a Windows Service Using TCP.
this works fine on my computer but when install this service in other computer in the same network got an error: The server has rejected the client credentials
I try to disable Firewall but still same error (and the service running...)
from the client side Add service reference works fine and recognize the service.

192.168.0.100 is the server machine IP address.
Try to use this config for tcp binding:

I have got a net.tcp Endpoint - the Service runs fine, just that this error is reported in the WCF Hosting.
Can someone explain what I've done wrong and how to correct it?
Thanks
