I am unable to resolve below error An unhandled exception of type 'System.TypeInitializationException' occurred in System.ServiceModel.dll
any suggestions?

    using (ServiceHost host=new ServiceHost(typeof(HelloService.HelloService)))

    {

        host.Open();

        Console.WriteLine("host started @" + DateTime.Now);

        Console.ReadLine();

    }

    stack trace for the error is mentioned below

I have made a demo and found there is no problem in the code snippet, I suggest you post more details about your project.

Here is my Console project, wish it is useful to you.
Server.

class Program

{

    static void Main(string args)

    {



        using (ServiceHost sh=new ServiceHost(typeof(MyService)))

        {

            sh.Open();

            Console.WriteLine("Service is ready....");



            Console.ReadLine();

            sh.Close();

        }

    }

}

[ServiceContract]

public interface IService

{

    [OperationContract]

    int Mult(int x, int y);

}

public class MyService : IService

{



    public int Mult(int x, int y)

    {

        OperationContext oc = OperationContext.Current;



        Console.WriteLine(oc.Channel.LocalAddress.Uri);

        return x * y;

    }       

 }

App.config

<system.serviceModel>

    <services>

      <service name="WCFServer1.MyService" behaviorConfiguration="mybehavior">

        <endpoint address="HelloService" binding="basicHttpBinding" contract="WCFServer1.IService"></endpoint>

        <endpoint address="HelloService" binding="netTcpBinding" contract="WCFServer1.IService"></endpoint>

        <host>

        <baseAddresses>

          <add baseAddress="http://localhost:5110"/>

          <add baseAddress="net.tcp://localhost:5120"/>

        </baseAddresses>

        </host>

      </service>

    </services>

    <behaviors>

      <serviceBehaviors>

        <behavior name="mybehavior">

          <serviceMetadata httpGetEnabled="true"/>

        </behavior>

      </serviceBehaviors>

    </behaviors>

  </system.serviceModel>

Result.

Feel free to let me know if there is anything I can help with.
