Unlike ASMX Web services, WCF Web services seem to break the WSDL up into a number of files.
My problem is that when I try to generate a proxy from a server that isn't the server, it'll get to the WSDL but then inside the WSDL's it'll have a number of imports, that it cannot access from the outside the server.
eg. this is one of the imports in my WSDL
http://alumninetworkservice.hha.test.idc:1315 is an internal address - I cannot access it from outside the server. Is there a way I can set up my service so that these WSDL references will be pointing to their internet URL?
Thanks
EDIT : I have pasted the configuration settings below.
This is on the server side.

Use useRequestHeadersForMetadataAddress behavior in the configuration of your service to overcome the problem. By default WCF always uses local address / dns name defined for the endpoint in WSDL. The behavior should enforce using the name from incoming host header (public address).

I ran my WCF service on the server without SSL enabled and now I moved it to one with SSL enabled and I am getting the following error:
Could not find a base address that matches scheme http for the endpoint with binding BasicHttpBinding. Registered base address schemes are [https].
Below are my settings:
<bindings>
<basicHttpBinding>
<binding name="basicHTTP">
<security mode="TransportCredentialOnly">
<transport clientCredentialType="Windows">
</transport>
</security>
</binding>
</basicHttpBinding>
</bindings>
<services>
<service behaviorConfiguration="basicBehavior" name="ProjectName.MyService">
<endpoint address="" binding="basicHttpBinding" bindingConfiguration="basicHTTP" contract="ProjectName.IMyService"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="basicBehavior">
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
How can I fix this error?
You need to define a binding for basicHttps. This is a very simple settings that works for SSL:
<system.serviceModel>
<bindings>
<basicHttpsBinding>
<binding name="BasicHttpBinding_IMyService" />
</basicHttpsBinding>
</bindings>
<client>
<endpoint
name="BasicHttpBinding_IMyService"
address="https://MyURL/MyService.svc/soap/"
binding="basicHttpsBinding"
bindingConfiguration="BasicHttpBinding_IMyService"
contract="ClientServiceReference.IMyService" />
</client>
</system.serviceModel>
Note: The endpoint needs to be defined and its URL is https.
Also, make sure that in production environment, you are not sending the exception details back to the caller (that would be considered a security hole in your system because exceptions can reveal too much information to hackers). You must change this line:
<serviceDebug includeExceptionDetailInFaults="false"/>
Fixed the issue by specifying security mode as Transport and using webHttpBinding
I am unable to connect to a WCF service hosted on our dev server but I am able to browse to it.
I am just trying to add a service reference via Visual Studio and when I click on Go, it gives me the following error.
An error occurred while receiving the HTTP response to http://...Service.svc. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.
My other colleagues are able to add the service reference and connect to this service with no issues, which makes it harder for me to understand the cause of this issue.

I'm trying to secure my WCF service using transport security model. I've successfully deployed my service to AppHarbor. But I'm getting the following exception when I try to access service page:
[InvalidOperationException: Could not find a base address that matches scheme https for the endpoint with binding BasicHttpBinding. Registered base address schemes are [http].] ...
I haven't uploaded any certificates, just using piggyback SSL there. I've downloaded the build and deployed it on my machine. It works fine.
Here is my system.serviceModel section of web.config:
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="TransportSecurity">
<security mode="Transport">
<transport clientCredentialType="None"/>
</security>
</binding>
</basicHttpBinding>

I've already tried this Hosting a WCF Web API app on AppHarbor?
Can somebody please explain me what I'm doing wrong?
This issue frequently appear when you communicate with the wcf web service thru the LB (AppHarbor one of the example of it).
You should know several things about such kind of communications.
1) Communication between yours client application and LB is secured (https is in use). So you should leverage security binding on the client side.
<basicHttpBinding>
<binding name="BasicHttpBinding_IAuthService">
<security mode="Transport">
<transport clientCredentialType="None" />
</security>
</binding>
</basicHttpBinding>
2) Communication between LB and web-front uses http, so server binding should be basicHttpBinding without extra configuration.
<endpoint binding="basicHttpBinding" contract="AuthService.IAuthService" />
Summarizing all that stuff we have
Client
<configuration>
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_IAuthService">
<security mode="Transport">
<transport clientCredentialType="None" />
</security>
</binding>
</basicHttpBinding>
</bindings>
<client>
<endpoint address="https://auth.apphb.com/AuthService.svc"
binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IAuthService"
contract="AuthService.IAuthService" name="BasicHttpBinding_IAuthService" />
</client>

Your approach is not going to work right off the bat. This is because SSL is terminated at the load balancers and the app servers see http traffic. You can read more about AppHarbor load balancers here.
You might be able to fool WCF with this module.
There are also some hints in this discussion: http://support.appharbor.com/discussions/problems/829-transportwithmessagecredential-https-ssl
I'm tackling with an issue but couldn't sort out it.
I have one service which is worked inside asp.net 4.0 app.
The site is available both over http and https.
Issue is that the service with below provided config snipped can work either over http or over https.
What is wrong in my config?
<system.serviceModel>
<bindings>
<webHttpBinding>
<binding name="webHttpsBinding">
<security mode="Transport">
<transport clientCredentialType="None"/>
</security>
</binding>
</webHttpBinding>
</bindings>
<behaviors>

<behavior name="HMS.DataServices.PaymentsServiceBehavior">
<enableWebScript />
</behavior>
</endpointBehaviors>
<serviceBehaviors>
<behavior name="HMS.DataServices.PaymentsServiceBehavior">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service name="HMS.DataServices.PaymentsService">
<!--HTTP-->
<endpoint address="" binding="webHttpBinding" contract="HMS.DataServices.IPaymentsService"
behaviorConfiguration="HMS.DataServices.PaymentsServiceBehavior" />
<!--HTTPS-->
<endpoint address="" binding="webHttpBinding" bindingConfiguration="webHttpsBinding"
contract="HMS.DataServices.IPaymentsService" behaviorConfiguration="HMS.DataServices.PaymentsServiceBehavior" />
</service>
</services>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
</system.serviceModel>
this config works over https but not nttp
In the windows log I see next error
The exception message is: Could not find a base address that matches scheme https for the endpoint with binding WebHttpBinding. Registered base address schemes are [http]..
Thanks in advance!
My WCF never worked with wsbinding, but when I switched to basic it worked fine.
What do I have to do to make wsbinding work?
Update
when I say it didn't work, I mean the client was never able to consume the services endpoints.
Do I have to add a username/password somewhere?
First, are you using Visual Studio 2005 or 2008? Next if you are using VS2005 did you install the .NET 3.0 CTP tools for WCF/WF that was released in 2006? I ask these questions because I wanted to know how you setup your proxy class in the client. Did you right click and do "add service reference" or "add web reference"
Also, does your WCF config file look similar to the below? This shows a dual setup, both Basic and WsHttp Bindings.
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="wsHttp">
<security mode="None">
<transport clientCredentialType="None" />
<message clientCredentialType="None" negotiateServiceCredential="false" establishSecurityContext="false" />
</security>
</binding>
</wsHttpBinding>
<basicHttpBinding>
<binding name="basicHttp"/>
</basicHttpBinding>
