              <endpoint address="soap" binding="basicHttpBinding" contract="PipeTest.ICalculatorService" >


                  <identity>
                      <dns value="localhost"/>
                  </identity>
              </endpoint>
              <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
			 
              <endpoint address="net.pipe://localhost" binding="netNamedPipeBinding" contract="PipeTest.ICalculatorService"  />
