I am having an issue debugging my WCF service when I set the WCF service to SSL Required in my local IIS. I am able to hit the URL correctly for my service under http/https but I cannot debug and step through the code. I received a popup box with the following text:
Unable to start debugging on the web server. The web server is not configured correctly.
When I make the service not SSL Required I am able to step through my code as expected. I am new to dealing with IIS and have gone through a number of tutorials with the same result. Any help would be awesome

1) First, I recommend checking the IIS logs. They are usually located in the following directory: C:\inetpub\logs\LogFiles. Just go into the W3SVC prefixed folder whose modification date most closely matches when you received the error. Open the log for the correct day and see the error details.
2) If that reveals nothing, then check out the Windows Application log in your Event Viewer.
3) Do you have a certificate (e.g. self signing certificate) on your computer? Is there a trusted site issue here?
I believe I found my answer. It looks like the checkbox in IIS for the website for Require SSL is associated the client certificate and requiring a client certificate to access the service instead of the section which is below it (although I will need to select required in the future). For the post I found When this is checked off I cannot debug the service but I can attach to the process in order to debug it.

If I am wrong please let me know. If I come across anything else I'll update this question again with my progress just to keep in documented.

Browsing http://myserver/services/Lookups.svc/Hello gives
Could not find a base address that matches scheme https for the endpoint with binding WebHttpBinding. Registered base address schemes are [http]
If I remove any one endpoint it works. Example removing endpoint configured with bindingConfiguration="httpWebBinding" works for HTTPS ,
How can I make it work with HTTP and HTTPS? As of now, I can able to use either http or https by removing one endpoint.
Referred How can I combine the WCF services config for both http and https in one web.config? and How do you setup HTTP and HTTPS WCF 4 RESTful services?
Note: In IIS, it is two web sites one listen on http and another on
https. Both sharing same code in physical folder
UPDATE: As of now, I removed endpoints and it works. But my concern is removing endpoing configured with behaviourConfiguration doesnt look great solution to me.
This works for both http & https

I've recreated your scenario and used your web.config to configure endpoints for my test service. Your configuration is ok and works correctly. The part that don't works for you is probably your https configuration in IIS. Make sure you have enabled https access to your service. If you test it with IISExpress from Visual Studio then left click on your project and in the properties window (View -> Properties Window ) select for SSL Enabled = True.
As #Lesmian pointed out in his answer, the issue is in your IIS configuration.
More specifically in:
Note: In IIS, it is two web sites one listen on http and another on https. Both sharing same code in physical folder
The reason is that IIS can not handle endpoints on a schema which it does not support.
You have two sites, and one of them has HTTP binding but does not has HTTPS, and the other has HTTPS but not HTTP.
So when you browse to http:// URL, IIS directs you to the (surprise!) http-enabled site, reads web.config, sees that it registers https endpoint (which is not supported by the site) and throws the exception telling that there is no https scheme support on the http-enabled-only site.
When you browse to the https:// URL the situation is similar - IIS does not allow you to use http endpoint on the https-enabled-only site.
To handle the issue you better use a single site with two bindings.
Another (and more complex) option would be using different web.configs for sites: set up separate sites (pointed to separate folders) and use the publishing and web.config transforming tools of the Visual Studio
Add This Code.
<protocolMapping>
<add scheme="http" binding="webHttpBinding" bindingConfiguration="httpWebBinding"/>
<add scheme="https" binding="webHttpBinding" bindingConfiguration="httpsWebBinding"/>
</protocolMapping>
I dont't know this query is still active or not but as i checked Please
Add binding="mexHttpsBinding" also
with binding="mexHttpBinding" with different endpoint
This helps me.
I am trying to host a svc service in my web application and I am trying to connect to it with a simple client application.
When the host is hosted in my own computer and solution, and I run the web application locally, everything works fine, meaning that I can add the reference to the service using add service reference in my client solution with http://localhost:6543/Hello.svc as the address and when I navigate to the service's url, it shows me the service's information as it should.
But when I publish my website, and I try to add the reference to my service using add service reference with http://myserver.com/Hello.svc as the address, i get the error message bleow:
There was an error downloading
'http://myserver.com/Hello.svc/_vti_bin/ListData.svc/$metadata'. The
request failed with HTTP status 404: Not Found. Metadata contains a
reference that cannot be resolved: 'http://myserverc.com/Hello.svc'.
The remote server returned an unexpected response: (405) Method Not
Allowed. The remote server returned an error: (405) Method Not
Allowed. If the service is defined in the current solution, try
building the solution and adding the service reference again.
and oddly when I navigate to myserver.com/Hello.svc, the browser starts to download the Hello.svc file instead of showing the service's details and information.
this is my website's web.config file:

I think I am missing something big here, but since I am new to WCF, I don't know what it is.Any help would be appreciated and I am more than happy to issue more details about my project if needed.
Thanks in advance
You need to run ServiceModel registration tool
"This command-line tool provides the ability to manage the registration of WCF and WF components on a single machine. Under normal circumstances you should not need to use this tool as WCF and WF components are configured when installed. But if you are experiencing problems with service activation, you can try to register the components using this tool."
I'm building an ASP.NET website - it's a solution with a few projects, a data base and a web service. Everything worked fine, but last time I tried to run the project, I got the following error:
There was no endpoint listening at http://localhost:[number]/BooksWS.svc that could accept the
message. This is often caused by an incorrect address or SOAP action. See InnerException,
if present, for more details.
The inner exception says:
Unable to connect to the remote server
This error sort of came out of the blue, so I'm not sure what additional information I should provide. Does anyone have any idea why this could happen?
I suppose even a general answer could help, the only info I found about this error in the web concerned WCF.
go to webconfig page of your site, look for the tag endpoint, and check the port in the address attribute, maybe there was a change in the port number
Another case I just had - when the request size is bigger than the request size set in IIS as a limit, then you can get that error too.
Check the IIS request limit and increase it if it's lower than you need.
Here is how you can check and change the IIS request limit:
Open the IIS
Click your site and/or your mapped application
Click on Feature view and click Request Filtering
Click - Edit Feature Settings.
I just found also another thread in stack
IIS 7.5 hosted WCF service throws EndpointNotFoundException with 404 only for large requests
An another possible case is make sure that you have installed WCF Activation feature.
Go to Server Manager > Features > Add Features
I had this problem when I was trying to call a WCF service hosted in a new server from a windows application from my local. I was getting same error message and at end had this "No connection could be made because the target machine actively refused it 127.0.0.1:8888". I donot know whether I am wrong or correct but I feel whenever the server was getting request from my windows application it is routing to something else. So I did some reading and added below in Web.config of service host project. After that everything worked like a magic.
<system.net>
<defaultProxy enabled="false">
</defaultProxy>
</system.net>
Short answer but did you have Skype open? This interferes specifically with ASP.NET by default (and localhosts in general) using port:80.
In Windows: Go to Tools -> Options -> Advanced -> Connection and uncheck the box "use port 80 and 443 as alternatives for incoming connections".
Try this:
Delete the service instance.
Create a new instance of the service.
Sometimes the port is changed and generated error.
I tried a bunch of these ideas to get HTTPS working, but the key for me was adding the protocol mapping. Here's what my server config file looks like, this works for both HTTP and HTTPS client connections:
<system.serviceModel>
<protocolMapping>
<add scheme="https" binding="wsHttpBinding" bindingConfiguration="TransportSecurityBinding" />
</protocolMapping>
<services>
<service name="FeatureService" behaviorConfiguration="HttpsBehavior">
<endpoint address="soap" binding="wsHttpBinding" contract="MyServices.IFeature" bindingConfiguration="TransportSecurityBinding" />
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="HttpsBehavior">
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
<behavior name="">
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
<bindings>
<wsHttpBinding>
<binding name="TransportSecurityBinding" maxReceivedMessageSize="2147483647">
<security mode="Transport">
<transport clientCredentialType="None" />
</security>
</binding>
</wsHttpBinding>
</bindings>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
If you are using custom binding, please make sure that you are putting the same name for both custom binding (Server and Client)in config files
<bindings>
<customBinding>
<binding name="BufferedHttpServerNoAuth" closeTimeout="00:10:00" openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00">
<gzipMessageEncoding innerMessageEncoding="textMessageEncoding" MaxArrayLength="10485760" MaxBytesPerRead="31457280" MaxStringContentLength="102400000" />
<httpsTransport hostNameComparisonMode="StrongWildcard" manualAddressing="False" maxReceivedMessageSize="31457280" authenticationScheme="Anonymous" bypassProxyOnLocal="True" realm="" useDefaultWebProxy="False" />
</binding>
</customBinding>
</bindings>
the binding name "BufferedHttpServerNoAuth" should be same in both.
Hope this would help someone
This is ancient history but I just ran into this issue and the fix for me was recycling the application pool of the website in IIS. Easy fix, for once.
I changed my website and app bindings to a new port and it worked for me. This error might occur because the port the website uses is not available. Hence sometimes the problem is solved by simply restarting the machine
-Edit-
Alternative (and easier) solution:reference
Get PID of process which is using the port
CMD command-
netstat -aon | findstr 0.0:80
Use the PID to get process name -
tasklist /FI "PID eq "
Open task manager, find this process and stop it.
(Note- Make sure you do not stop Net.tcp services)
I solved it by passing the binding with endpoint.
"http://abcd.net/SampleFileService.svc/basicHttpWSSecurity"
Click on Service which you have created right click on it then select update references after this rebuild the application it will work
This is my first time using WCF. It was very easy to develop the application however it's turning me nuts to deploy on IIS.
I've tried everything to deploy it, however the client started throwing unauthorized user exception (or something like that) to an Undefined exception (after countless changes in web.config file and app.config file).
I'm back to the default configurations which work fine in VS (cassini).
Any quick pointers or some link to a detailed tutorial would be much appreciated.
Thanks in advance

Not specific to your case, however WCF Tracing is generally a really good tool to diagnose WCF configuration problems. You can see here how you can configure WCF tracing, it is really simple, the WCF runtime will basically emit some information into a .svclog file
Then you can analyze the log with the Service Trace Viewer Tool (it is in All Programs->Visual Studio 2010->Microsoft Windows SDK Tools), and see what went wrong during specific requests, it gives much more information than the exception messages.
Jonny,
This is a long shot but once I had the same problem (unauthorized access) and the problem was that some files (downloaded from a webmail) was blocked by windows. As soon I unblocked these files the web service started to work fine.
Hope it helps.
My WCF service was working correctly and then all of sudden it stop working. I don't think I changed anything with the configuration.
The WCF service is hosted by a windows service.
What is weird is when I add the service reference, it will identify the contract and all the methods exposed. But if I go to a browser I get a 404 error and the compiler is not creating the service. I have deleted and tried to re-add the reference with no luck
Also, my deployed application is still able to access the wcf service.
Question 1:
In a WCF windows service, should I be able to see the wsdl inside a browser (http://localhost:8080/MaestroService/mex). In IE, I am getting 400 Bad Request. I am assuming that this is the root of the problem.
Question 2:
Is there something else?

XPath to Error Source: //wsdl:definitions[#targetNamespace='http://tempuri.org/']/wsdl:binding[#name='basicHttp']
Update
I turned on the tracing and I saw this:
The message with To 'http://localhost:8080/MaestroService/mex/mex' cannot be processed at the receiver, due to an AddressFilter mismatch at the EndpointDispatcher. Check that the sender and receiver's EndpointAddresses agree. I will update this question if I figure it out.
Update V2
I went to another project inside the same solution. I was able to add the service there with no problems. I notice I was using 3.5 in the console app vs 4.0 in the wpf browser app. When I came back to report this, I noticed in my last update that it had /mex/mex even though I put http://localhost:8080/MaestroService/mex in the url . I tried just http://localhost:8080/MaestroService and it work!!!
In the end, I did end up using Migual Castro technique here, where you create the conracts and the proxy. Which was good to see how it really works and what VS is doing. But it would be good to have that day and a half back.
thanks for the suggestions everyone.
You are running as a windows service.
A windows service runs in the security context of a user account.
If the password of the user account changes or expires, the service does not run.
The first thing that you should check is: Is the service running.
