Hey, here is my class code
namespace WcfServicepractice
{
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class WebDataService1 : IMyclass
{
public int add(int a, int b)
{
return a + b;
}
public int multi(int a, int b)
{
return a * b;
}
}
}
this is my Interface code,
namespace WcfServicepractice
{
[ServiceContract]
public interface IMyclass
{
[OperationContract]
int add(int a,int b);
[OperationContract]
int multi(int a, int b);
}
}
this is my web.config for my service
<behavior name="WcfServicepractice.WebDataService1Behavior">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
<service name="WcfServicepractice.WebDataService1" behaviorConfiguration="WcfServicepractice.WebDataService1Behavior" >
<endpoint address="" binding="wsHttpBinding" contract="WcfServicepractice.IMyclass" >
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
When i run the code i get this error
The webpage cannot be found
Can someone help ?
Thanks..
From your error I assume you're trying to host the service in IIS (in this case probably using the Cassini server)
Do you have a svc file in your project?
What address are you browsing to?
You should be browsing to something like: http://localhost:someport/service.svc

I'm having some difficulties getting SwaggerWCF to load my documentation page, and I'm not sure why. I get no errors, but I also get no Swagger docs either, just a 404 when I visit http://localhost:8733/docs per the endpoint configuration. What am I doing wrong here? I have everything decorated up, using Framework 4.8. Service works fine and the mex and js endpoints will return data, just no swaggerUI.
Here is my App.Config:

Add an endpoint to your App.config file.
<services>
<service name="SwaggerWcf.SwaggerWcfEndpoint">
<endpoint address="http://localhost/docs" binding="webHttpBinding" contract="SwaggerWcf.ISwaggerWcfEndpoint" />

Create a WebServiceHost
var swaggerHost = new WebServiceHost(typeof(SwaggerWcfEndpoint));
swaggerHost.Open();
You can refer to the steps provided in the link for details.

How do I view my Swagger docs when using SwaggerWcf?
I have a service contract defined as:
[System.ServiceModel.ServiceContractAttribute(Namespace = "http://www.ans.gov.br/tiss/ws/tipos/tisscancelaguia/v30001", ConfigurationName = "ItissCancelaGuia")]
public interface ItissCancelaGuia
{
[System.ServiceModel.OperationContractAttribute(Action = "tissCancelaGuia", ReplyAction = "*")]
[System.ServiceModel.FaultContractAttribute(typeof(tissFaultWS), Action = "", Name = "tissFaultWS", Namespace = "http://www.ans.gov.br/padroes/tiss/schemas")]
[System.ServiceModel.XmlSerializerFormatAttribute(SupportFaults = true)]
[System.ServiceModel.ServiceKnownTypeAttribute(typeof(SignatureType))]
mensagemTISS tissCancelaGuia_Operation(string mensagem);
}
And the implementation:
[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Single, ConfigurationName = "CancelaGuiaTS")]
public sealed class tissCancelaGuia : ItissCancelaGuia
{...}
and also the relevant parts of the web.config:
<service behaviorConfiguration="tissCancelaGuiaStringServiceBehavior"
name="CancelaGuiaTS">
<endpoint address="" behaviorConfiguration="EndPointValidation"
binding="basicHttpBinding" bindingConfiguration="TISSv3_binding"
name="CancelaGuiaTs" contract="ItissCancelaGuia" />
<endpoint address="mex" binding="mexHttpBinding" name="CancelaGuiaTsMetadata"
contract="IMetadataExchange" />
</service>
and
<behavior name="tissCancelaGuiaStringServiceBehavior">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
The service compiles correctly but the wsdl exposed contains no operations.
The only solution I can think of is to write the wsdl manually and expose it through the externalMetadataLocation attibute of the serviceMetadata, but it just don't feel right to me.
Edit 1
Here the definition of the mensagemTISS class
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "4.0.30319.1")]

[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]

public partial class mensagemTISS

Don't know if it is important but the class have this property:
[System.Xml.Serialization.XmlElementAttribute("operadoraParaPrestador", typeof(operadoraPrestador), Order=1)]
[System.Xml.Serialization.XmlElementAttribute("prestadorParaOperadora", typeof(prestadorOperadora), Order=1)]
public object Item
{
get

set

defined as a choice in the originating schema.
I am hosting WCF as Windows Service using net.tcp. After installing the windows service when I start the service, I get that service was started and stopped.
The error says in order to In order to add an endpoint to the service 'MYService', a non-empty contract name must be specified.
at System.ServiceModel.Description.ConfigLoader.LookupContract(String contractName, String serviceName)
My OnStart function is as follows
protected override void OnStart(string[] args)
{
try
{
if (myServiceHost != null)
{
myServiceHost.Close();
}
myServiceHost = new ServiceHost(typeof(MYservice));
myServiceHost.Open();
}
catch (Exception ex)
{
log.Error("ONStart", ex);
throw;
}
}
The config file is as follows:
<serviceHostingEnvironment minFreeMemoryPercentageToActivateService="10" />
<services>
<service behaviorConfiguration="myServiceBehavior"
name="myNamespace.myTestService">
<endpoint binding="netTcpBinding" bindingConfiguration="netTCPBindingConfig" contract="myNamespace.ServiceInterface.ImyTestService" />
<endpoint binding="mexTcpBinding" bindingConfiguration="" />
<host>
<baseAddresses>
<add baseAddress="net.tcp://10.1.3.69:8523/TestService" />
</baseAddresses>
<timeouts closeTimeout="10:00:10" openTimeout="10:01:00" />
</host>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="myServiceBehavior">
<serviceMetadata httpGetEnabled="false" httpsGetEnabled="false" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
In your config file, there is:
<endpoint binding="netTcpBinding" bindingConfiguration="netTCPBindingConfig" contract="myNamespace.ServiceInterface.ISomeService" /> `
Instead of ISomeService, you must specify whichever interface is implemented by MYService.
EDIT
Additionally, mex binding must have a contract specified, i.e. contract="IMetadataExchange"
EDIT AGAIN
For your convenience, this is how your mex binding should look like:
<endpoint binding="mexTcpBinding" address="mex" bindingConfiguration="" contract="IMetadataExchange" />
Please try this:
protected override void OnStart(string[] args)
{
try
{
myServiceHost = new ServiceHost(typeof(MYservice));
myServiceHost.Open();
Console.ReadKey();
}
catch (Exception ex)
{
log.Error("ONStart", ex); throw;
}
finally
{
myServiceHost.Close();
}
}
Hi a have WCF service libary with this configuration:
<?xml version="1.0"?>
<configuration>
<system.serviceModel>
<services>
<service behaviorConfiguration="Default" name="ComDocs.ControlServerServiceLibary.Concrete.TokenService">
<host>

<add baseAddress="http://localhost:8080/TokenService" />
</baseAddresses>
</host>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />

If I build it in debug, everything works fine on localhost. But if I make a Windows Service library with the same configuration:
public partial class TokenService : ServiceBase
{
ServiceHost _host = null;
public TokenService()
{
InitializeComponent();
}
protected override void OnStart(string[] args)
{
Trace.WriteLine("Starting Token Service...");
_host = new ServiceHost(typeof(TokenService));
_host.Open();
}
protected override void OnStop()
{
Trace.WriteLine("Shutting down Token Service...");
if (_host != null)
{
_host.Close();
_host = null;
}
}
}
Install it with InstallUtil and start it:
but error:
I suspect this line is the culprit.
_host = new ServiceHost(typeof(TokenService));
TokenService is your Windows service class, not your WCF service class.
This is my first WCF service and I am getting an error:

I think your contract may need to point to the interface and not the concrete implementation
