WCF with basic authentification (Remote Server returned an error: 404 Not found)

I am trying to access my wcf (http protocol using port 26880) service externally (deployed on IIS) after setting it up with a Basic Authentication Module, but it throws the following error:
The remote server returned an error: (404) Not Found.
What I have tried so far:
Removed the basic authentication and checked that the service can be accessed both internally and externally and that works.
Checked that the service actually receives the header authorization and the user is logged in.(This works)
Added the following line in my web.config file:
<modules runAllManagedModulesForAllRequests="true">
after adding my BasicAuthenticationModule and still no luck.
Went in IIS and made sure that BasicAuthentication is enabled.
Enabled trace logging and apparently I cannot see any errors besides the fact that it looks at this address: http://localhost/ResponseService
when in fact it should be http://localhost:26880/ResponseService
I have googled and tried every possible solution that I found related to my error and no results so far.
This is my web.config file:

}
}
catch (WebException webEx)
{
Console.WriteLine("Web exception :" + webEx.Message);
}
catch (Exception ex)
{
Console.WriteLine("Exception :" + ex.Message);
}
}
Based on the error I am getting I'm assuming that it can't find a file or my web.config is not setup properly? Any new ideas?

WCF service streaming images

I'd like to make WCF service which can put image into stream.
I have next in config:
<service name="Images" behaviorConfiguration="ImagesBehavior">
<endpoint address="http://localhost:5523/Images.svc"
binding="basicHttpBinding" contract="Images" />
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="http://localhost:5523/Images" />
</baseAddresses>
</host>
</service>
<behavior name="ImagesBehavior">
<serviceDebug includeExceptionDetailInFaults="true" />
<serviceMetadata httpGetEnabled="true" />
</behavior>
And code:
[OperationContract]
[WebGet(UriTemplate = "GetImage/{imageID}",
BodyStyle = WebMessageBodyStyle.Bare)]
public Stream GetImage(string imageID)
{
try
{
if (WebOperationContext.Current != null)
WebOperationContext.Current.OutgoingResponse.ContentType = "image/jpeg";
var ms = new MemoryStream(myImage);
return ms;
}
catch (Exception e)
{
if (WebOperationContext.Current != null)
WebOperationContext.Current.OutgoingResponse.ContentType = "text/xml";
Console.WriteLine("GetImage ERROR:" + e.Message + "\r\n" + e.StackTrace);
byte[] errorBytes = Encoding.UTF8.GetBytes("ERROR");
return new MemoryStream(errorBytes);
}
}
But when I'm trying this via browser like
http://localhost:5523/Images.svc/GetImage/imagecodeblabla
I've got
400 Bad Request
And when
http://localhost:5523/Images/GetImage/imagecodeblabla
405 Method Not Allowed
What's wrong?

Is your service SOAP or REST? It appears that you're using REST syntax (WebGetAttribute) but your binding is BasicHttpBinding (SOAP).
Try using WebHttpBinding instead and see how that goes!

Running wcf service without App.config doesn't work

I create simple wcf host in console application. It doesn't work and the exception make NO SENSE:/
The exception looks really wierd:
"ContractDescription 'IFooService' has zero operations; a contract
must have at least one operation."
because, here is the code and i I have an operation:
[ServiceContract]
public interface IFooService
{
[OperationContract]
void DoNothing();
[OperationContract]
int GetFoo(int i);
}
public class FooService : IFooService
{
public void DoNothing()
{
}
public int GetFoo(int i)
{
return i + 1;
}
}
class Program
{
static void Main(string[] args)
{
try
{
string address = "http://localhost:9003/FooService";
Uri addressBase = new Uri(address);
var svcHost = new ServiceHost(typeof(FooService), addressBase);
BasicHttpBinding bHttp = new BasicHttpBinding();
Type contractType = typeof(IFooService);
ContractDescription contractDescription = new ContractDescription(contractType.Name);
contractDescription.ProtectionLevel = ProtectionLevel.None;
contractDescription.ContractType = contractType;
contractDescription.ConfigurationName = contractType.FullName;
contractDescription.SessionMode = SessionMode.NotAllowed;
svcHost.AddServiceEndpoint(new ServiceEndpoint(contractDescription, bHttp, new EndpointAddress(address)));
svcHost.Open();
Console.WriteLine("\n\nService is Running as >> " + address);
}
catch (Exception ex)
{
Console.WriteLine(ex);
}
Console.ReadKey();
}
}
This is basically entire code. App.config is left untouched:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />
</startup>
</configuration>
EDIT: A little clue, this way it works: I didn't change service or contract, but moved configuration to App.config, so changed only Main method:
App.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />
</startup>
<system.serviceModel>
<services>
<service name="WcfDemos.ConsoleHost.FooService">
<endpoint address="http://localhost:9003/FooService" binding="basicHttpBinding"
contract="WcfDemos.ConsoleHost.IFooService" />
</service>
</services>
</system.serviceModel>
</configuration>
Main:
static void Main(string[] args)
{
try
{
string address = "http://localhost:9003/FooService";
Uri addressBase = new Uri(address);
var svcHost = new ServiceHost(typeof(FooService), addressBase);
svcHost.Open();
Console.WriteLine("\n\nService is Running as >> " + address);
}
catch (Exception ex)
{
Console.WriteLine(ex);
}
Console.ReadKey();
}

Why do you need to use the ContractDescription? I suppose it looks for the settings in the configuration file.
You may do the following (use the AddServiceEndpoint method without ContractDescription):
static void Main(string[] args)
{
try
{
string address = "http://localhost:9003/FooService";
Uri addressBase = new Uri(address);
var svcHost = new ServiceHost(typeof(FooService), addressBase);
BasicHttpBinding bHttp = new BasicHttpBinding();
//Type contractType = typeof(IFooService);
//ContractDescription contractDescription = new ContractDescription(contractType.Name);
//contractDescription.ProtectionLevel = ProtectionLevel.None;
//contractDescription.ContractType = contractType;
//contractDescription.ConfigurationName = contractType.FullName;
//contractDescription.SessionMode = SessionMode.NotAllowed;
//svcHost.AddServiceEndpoint(new ServiceEndpoint(contractDescription, bHttp, new EndpointAddress(address)));
svcHost.AddServiceEndpoint(typeof(IFooService).ToString(), bHttp, address);
svcHost.Open();
Console.WriteLine("\n\nService is Running as >> " + address);
}
catch (Exception ex)
{
Console.WriteLine(ex);
}
Console.ReadKey();
}
BTW here you may find some library for configuring your WCF services without app.config files: WCF NetTcpBinding Bootcamp

I believe you have to add an endpoint to the ServiceHost if you don't provide the endpoints in the config file. See the AddServiceEndpoint call:
Uri baseAddr = new Uri("http://localhost:8000/WCFService1");
ServiceHost localHost = new ServiceHost(typeof(CalculatorService), baseAddr);
try
{
localHost.AddServiceEndpoint(typeof(ICalculator), new WSHttpBinding(), "CalculatorService");
ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
smb.HttpGetEnabled = true;
localHost.Description.Behaviors.Add(smb);
localHost.Open();
Console.WriteLine("Service initialized.");
Console.WriteLine("Press the ENTER key to terminate service.");
Console.WriteLine();
Console.ReadLine();
localHost.Close();
}
catch (CommunicationException ex)
{
Console.WriteLine("Oops! Exception: {0}", ex.Message);
localHost.Abort();
}
http://www.programminghelp.com/dotnet/wcf-creating-and-implementing-a-service-in-c/

The above comes from Microsoft example:
https://learn.microsoft.com/en-us/dotnet/framework/wcf/how-to-host-and-run-a-basic-wcf-service
which is a great place to start. Nonetheless ... it is still unclear what needs to be added in code to make the app.config content below redundant:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
</appSettings>
<system.web>
<compilation debug="true" />
</system.web>
<!-- When deploying the service library project, the content of the config file must be added to the host's

<system.serviceModel>
<services>

How to use HTTPS with WCF SessionMode.Required - simplest possible example

UPDATE (8/7/2014) - The solution to this problem was that I needed to add a class that derived from "UserNamePasswordValidator" and register it in Web.Config.
I have created a simple test WCF service and test console client application (see below for code). I am using .NET 4.5.1. I have already searched for duplicates on StackOverflow (found similar posts here and here) - however I feel that the referenced posts are potentially outdated, and also feel that my post is more limited in scope.
OK now for the example:
The solution currently uses sessions (in ITestService.cs):
[ServiceContract(SessionMode = SessionMode.Required)]
... and uses wsHttpBinding (see below app.config and web.config).
When I deploy this to a server, I am successfully able to access it via a web browser using HTTPS like this: https://myserver.com/test/testservice.svc
However, when I change the endpoint in the client app.config from:
http://localhost:20616/TestService.svc/TestService.svc
to:
https://myserver.com/test/testservice.svc
and run the console application again, I receive the error: "The provided URI scheme 'https' is invalid; expected 'http'. Parameter name: via"
My question is, what is the minimum changes I need to make for this to work, without changing SessionMode.Required?
Here is the client console application code. Please be sure to change the App.Config value for "mycomputer\Matt" to the correct value for your machine.
Program.cs
using System;
namespace TestClient
{
class Program
{
static void Main(string[] args)
{
Console.Clear();
Console.WriteLine("Attempting to log in...");
try
{
TestServiceReference.TestServiceClient client = new TestServiceReference.TestServiceClient();
bool loginSuccess = client.LogIn("admin", "password");
if (loginSuccess)
{
Console.WriteLine("Successfully logged in.");
string secretMessage = client.GetSecretData();
Console.WriteLine("Retrieved secret message: " + secretMessage);
}
else
{
Console.WriteLine("Log in failed!");
}
}
catch (Exception exc)
{
Console.WriteLine("Exception occurred: " + exc.Message);
}
Console.WriteLine("Press ENTER to quit.");
Console.ReadLine();
}

UNABLE to POST data to WCF from Android

I'm trying to send data to WCF service from an Android Application but somehow the service doesn't seems to be call through the android. I received a STATUSCODE value = 500 through adnroid in LOGCAT (which means the Internal Server Error) I go through the source code 100 times but didn't figure out the Bug. and almost checked all the posts related to my problem but still didn't get any solution.
HERE IS THS CODE
Android Code:
private class sendPostData extends AsyncTask<String, Void, String>
{
#Override
protected String doInBackground(String... params) {
// TODO Auto-generated method stub
HttpPost request = new HttpPost( LOGIN_SERVICE_URL + "/MyCar");
request.setHeader("Accept", "application/json");
request.setHeader("Content-type", "application/json");
JSONStringer getCarInfo;
try {
getCarInfo = new JSONStringer()
.object()
.key("myCar")
.object()
.key("Name").value(edt_carName.getText().toString())
.key("Make").value(edt_carMake.getText().toString())
.key("Model").value(edt_carModel.getText().toString())
.endObject()
.endObject();
StringEntity entity = new StringEntity(getCarInfo.toString());
request.setEntity(entity);
// Send request to WCF service
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpResponse response = httpClient.execute(request);
Log.d("WebInvoke", "Saving : " + response.getStatusLine().getStatusCode());
}
catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(String result) {
txt_verif.setText("Success");
}
}
everything is working fine in android code except calling the WCF service. I Debug the code several times and received statuscode = 500
HERE is the WCF Service
Service.cs
public class Service1 : IService1
{
public void UpdateMyCar(myCar myCar) {
string strConnectionString = ConfigurationManager.ConnectionStrings["Database1"].ConnectionString;
SqlConnection conn = new SqlConnection(strConnectionString);
conn.Open();
using (SqlCommand cmd = new SqlCommand("Insert into TestingTable (Name,Make,Model) Values (#Name,#Make,#Model)", conn)) {
cmd.Parameters.AddWithValue("#Name", myCar.Name);
cmd.Parameters.AddWithValue("#Make", myCar.Make);
cmd.Parameters.AddWithValue("#Model", myCar.Model);
int queryResult = cmd.ExecuteNonQuery();
} conn.Close();
}

this service is also publish on IIS. and I also checked that service with google chrome extension SIMPLE REST CLIENT and received an internal server error

The problem is your host name doesn't match what you are using from the phone.
You can turn off address filter to fix this temporarily:
[ServiceBehavior(AddressFilterMode=AddressFilterMode.Any)]
public class Service1 : IService1
{
....
}
But you should fix the hostname when you release to production

Create a domain in your machine with proper port number and make sure you are able to call the service using the Google's Rest client.If it works,then you won't find any issue if you call the same using your android phone.
Following article will help to setup virtual directory with proper port number.[http://www.hosting.com/support/iis7/create-new-sites-in-iis-7/]
Note you can't call localhost directly from your mobile.atleast try to call the service with ipaddress.[http://localhost/service/mycar] =>[http://DemoService/service/mycar]

The following code will help you to debug your code a little bit deep.
catch (Exception ex)
{
WebException webexception = (WebException)ex;
var responseresult = webexception.Response as HttpWebResponse;
//Code to debug Http Response
var responseStream = webexception.Response.GetResponseStream();
string fault_message = string.Empty;
int lastNum = 0;
do
{
lastNum = responseStream.ReadByte();
fault_message += (char)lastNum;
} while (lastNum != -1);
responseStream.Close();
}

Never mind, I have made several changes in web.config file and got the solution. <endpointBehaviors> tag was missing in my case and several other things. here is the updated code of web.config file.
