WCF Servislerinde Unity Kullanımı

WCF servislerinizde Unity veya farklı bir Dependency Injection Framework’u kullanmak istiyorsanız aşağıdaki makale oldukça yardımcı.

Kendimize özel ServiceHostFactory oluşturup register işlemlerini istediğimiz gibi yapabiliyoruz.

 

http://msdn.microsoft.com/en-us/library/vstudio/hh273093(v=vs.100).aspx

 

Dikkat edilmesi gereken önemli bir not:

** WcfHostClient.exe üzerinden host işlemi yapıyorsanız (development ortamında) kendinize özel ServiceHostFactory’i kullanamıyorsunuz. Bunu aşmak için WebHost isimli bir proje yaratın ve svc dosyanızı yaratın.

Svc dosyada aşağıdaki gibi Factory tanımı yapın. Bu projeyi hem development ortamında, hem de devreye alımlarda kullanabilirsiniz.

 

<%@ ServiceHost Service="Service.Wcf.Service1" Factory="Service.Wcf.MyServiceHostFactory"%>

IIS'e WCF Servis Deploy'unda BaseAddress

Selamlar,

Bildiğiniz gibi WCF servislerini farklı ortamlarda host edebilirsiniz.

Biz şirket içinde yazdığımız wcf servisleri genelde IIS sunucularında yayınlıyoruz.

Hemen hemen her devreye alımda da endpoint’lerin URI’ları konusunda sorunlar yaşıyoruz J

Burada bilinmesi ve dikkat edilmesi gereken en önemli nokta; IIS servisin svc dosyasını base olarak kabul etmektedir.

Dolayısıyla web.config dosyasına baseaddress eklememeliyiz.

Örnek servis ve client configleri ile konu daha iyi anlaşılacaktır.

Hem netTcp hem de basicHttp binding destekleyen bir servisimiz olsun.

IIS’te basicHttp için 8018, netTcp için 8019 portlarını ayarladık. Svc dosyamızın ismi DistributedService.Wcf.ScheduledJobsService.svc şeklinde ve herhangi bir sub folder’ın altında değil.

Birden fazla endPoint tanımladığımız için bunların relative adreslerini de belirtmemiz gerekiyor. netTcp için address kısmına netTcpAdres diye bir giriş yaptım. Servis referans olarak eklenebilmesi için mexTcpBinding eklendi ve ona da özel bir adres atandı (mexTcpAdres).

<system.serviceModel>

    <services>

      <service behaviorConfiguration="Basic_Service_Behavior" name="DistributedService.Wcf.ScheduledJobsService">

        <endpoint address="netTcpAdres" binding="netTcpBinding" bindingConfiguration="ScheduledJobsServiceBinding" contract="DistributedService.Contracts.Interfaces.IScheduledJobsService"/>

        <endpoint address="mexTcpAdres" binding="mexTcpBinding" bindingConfiguration="" contract="IMetadataExchange"/>

        <endpoint address="" binding="basicHttpBinding" bindingConfiguration="ScheduledJobsServiceBindingHttp" contract="DistributedService.Contracts.Interfaces.IScheduledJobsService"/>

        <endpoint address="mex" binding="mexHttpBinding" bindingConfiguration="" contract="IMetadataExchange"/>

      </service>

    </services>

    <behaviors>

      <serviceBehaviors>

        <behavior name="Basic_Service_Behavior">

          <serviceDebug includeExceptionDetailInFaults="true"/>

          <serviceMetadata/>

        </behavior>

      </serviceBehaviors>

    </behaviors>

    <bindings>

      <netTcpBinding>

        <binding name="ScheduledJobsServiceBinding" maxReceivedMessageSize="900000000" receiveTimeout="00:15:00" sendTimeout="00:15:00">

          <reliableSession inactivityTimeout="15:00:00"/>

        </binding>

      </netTcpBinding>

      <basicHttpBinding>

        <binding name="ScheduledJobsServiceBindingHttp" maxReceivedMessageSize="900000000" receiveTimeout="00:15:00" sendTimeout="00:15:00"/>

      </basicHttpBinding>

    </bindings>

</system.serviceModel>

Visual Studio’da bir test projesi yarattık ve service referans olarak ekleme yaptık.

Oluşan config dosyası şu şekilde:

<system.serviceModel>

    <bindings>

      <basicHttpBinding>

        <binding name="BasicHttpBinding_IScheduledJobsService" closeTimeout="00:01:00"

          openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"

          allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"

          maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"

          messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"

          useDefaultWebProxy="true">

          <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"

            maxBytesPerRead="4096" maxNameTableCharCount="16384" />

          <security mode="None">

            <transport clientCredentialType="None" proxyCredentialType="None"

              realm="" />

            <message clientCredentialType="UserName" algorithmSuite="Default" />

          </security>

        </binding>

      </basicHttpBinding>

      <netTcpBinding>

        <binding name="NetTcpBinding_IScheduledJobsService" closeTimeout="00:01:00"

          openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"

          transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions"

          hostNameComparisonMode="StrongWildcard" listenBacklog="10" maxBufferPoolSize="524288"

          maxBufferSize="65536" maxConnections="10" maxReceivedMessageSize="65536">

          <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"

            maxBytesPerRead="4096" maxNameTableCharCount="16384" />

          <reliableSession ordered="true" inactivityTimeout="00:10:00"

            enabled="false" />

          <security mode="Transport">

            <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" />

            <message clientCredentialType="Windows" />

          </security>

        </binding>

      </netTcpBinding>

    </bindings>

    <client>

      <endpoint address="net.tcp://testapp.bimar.com:8019/DistributedService.Wcf.ScheduledJobsService.svc/netTcpAdres"

        binding="netTcpBinding" bindingConfiguration="NetTcpBinding_IScheduledJobsService"

        contract="ServiceReference1.IScheduledJobsService" name="NetTcpBinding_IScheduledJobsService">

        <identity>

          <servicePrincipalName value="host/ testapp.bimar.com" />

        </identity>

      </endpoint>

      <endpoint address="http:// testapp.bimar.com:8018/DistributedService.Wcf.ScheduledJobsService.svc"

        binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IScheduledJobsService"

        contract="ServiceReference1.IScheduledJobsService" name="BasicHttpBinding_IScheduledJobsService" />

    </client>

  </system.serviceModel>

Renkli kısımlarda gördüğünüz gibi;

Baseadress olarak svc dosyası görünüyor. BasicHttp için özel bir adres vermemiştik. netTcp için verdiğimiz özel adres (netTcpAdres) base adrese eklenmiş durumda.

Calling WCF Service with Service Reference

Doğru Kullanım

ServiceReference1.ArdTarifeServiceClient obj = new ServiceReference1.ArdTarifeServiceClient();

                    using (obj)

                    {

                        string s = (obj.Increment().ToString());

                    }

Daha Doğru Kullanım

bool mSuccess = false;

            ServiceReference1.ArdTarifeServiceClient obj = new ServiceReference1.ArdTarifeServiceClient();

            try

            {

                string s = obj.Increment().ToString();

                obj.Close();

                mSuccess = true;

            }

            finally

            {

                if (!mSuccess)

                    obj.Abort();

wcf servisi ( WcfSvcHost ) / LLBLGenPro 64 Bit Problem - wcf service ( WcfSvcHost ) / LLBLGenPro 64 bit problem workaround

64 bit bilgisayarlarda wcf projesi yapiyorsaniz, wcfsvchost.exe kullanarak wcf servisini host ediyorsaniz, 32bit derlenmis dll lerin kullaniminda sıkıntı yasayabilirsiniz.

Sorun MS’un bir bug’indan kaynaklaniyor. Uygulama 32 bit calissa bile host.exe yi 64 bit calistiriyor. Workaround var. Corflags.exe kullanilarak wcfsvchost.exe ye her zaman 32 bit calis denilebiliyor.
