c# - WCF Service enable tracing -


after 2 days of try , error , blind debugging, web service still produces error in cases , now, don't know why. therefor, enable tracing service in order have @ least little feedback.

however, tried few addition web.config, none ever produced trace file, if service responded error.

so long, web.config:

    <?xml version="1.0" encoding="utf-8"?>     <configuration>     <configsections>     <section name="entityframework"        type="system.data.entity.internal.configfile.entityframeworksection, entityframework, version=6.0.0.0, culture=neutral, publickeytoken=b77a5c561934e089" requirepermission="false" />      </configsections>      <connectionstrings>      <...removed here... />      </connectionstrings>     <appsettings>     <add key="aspnet:usetaskfriendlysynchronizationcontext" value="true" />     </appsettings>     <system.web>     <customerrors mode="off"></customerrors>     <compilation targetframework="4.5.1" />     <httpruntime targetframework="4.5.1" />     </system.web>     <system.servicemodel>     <services>       <service name="timerechomepage.service.timeservice" behaviorconfiguration="timeservicebehavior">         <endpoint name="webhttpbinding" address="" binding="webhttpbinding" bindingconfiguration="webhttptransportsecurity" contract="timerechomepage.service.itimeservice" behaviorconfiguration="webhttp" />         <endpoint name="mexhttpbinding" address="mex" binding="mexhttpsbinding" contract="imetadataexchange" />       </service>       </services>       <bindings>       <webhttpbinding>         <binding name="webhttptransportsecurity">           <security mode="transport" />         </binding>       </webhttpbinding>     </bindings>     <behaviors>       <servicebehaviors>         <behavior name="timeservicebehavior">           <servicemetadata httpsgetenabled="true" />           <servicedebug includeexceptiondetailinfaults="false" />         </behavior>         <behavior>           <servicemetadata httpgetenabled="false" httpsgetenabled="true" />           <servicedebug includeexceptiondetailinfaults="true" />         </behavior>       </servicebehaviors>       <endpointbehaviors>         <behavior name="webhttp">           <webhttp defaultoutgoingresponseformat="json" automaticformatselectionenabled="true" defaultbodystyle="wrappedrequest" />         </behavior>       </endpointbehaviors>     </behaviors>     <protocolmapping>       <add binding="basichttpsbinding" scheme="https" />     </protocolmapping>     <servicehostingenvironment aspnetcompatibilityenabled="true" multiplesitebindingsenabled="true" />   </system.servicemodel>   <system.webserver>     <modules runallmanagedmodulesforallrequests="true" />     <directorybrowse enabled="false" />   </system.webserver>   <entityframework>     <defaultconnectionfactory type="system.data.entity.infrastructure.localdbconnectionfactory, entityframework">       <parameters>         <parameter value="v13.0" />       </parameters>     </defaultconnectionfactory>     <providers>       <provider invariantname="system.data.sqlclient" type="system.data.entity.sqlserver.sqlproviderservices, entityframework.sqlserver" />     </providers>   </entityframework>   <runtime>     <assemblybinding xmlns="urn:schemas-microsoft-com:asm.v1">       <dependentassembly>         <assemblyidentity name="newtonsoft.json" publickeytoken="30ad4fe6b2a6aeed" culture="neutral" />         <bindingredirect oldversion="0.0.0.0-8.0.0.0" newversion="8.0.0.0" />       </dependentassembly>       <dependentassembly>         <assemblyidentity name="system.web.mvc" publickeytoken="31bf3856ad364e35" culture="neutral" />         <bindingredirect oldversion="0.0.0.0-5.1.0.0" newversion="5.1.0.0" />       </dependentassembly>       <dependentassembly>         <assemblyidentity name="webgrease" publickeytoken="31bf3856ad364e35" culture="neutral" />         <bindingredirect oldversion="0.0.0.0-1.5.2.14234" newversion="1.5.2.14234" />       </dependentassembly>       <dependentassembly>         <assemblyidentity name="antlr3.runtime" publickeytoken="eb42632606e9261f" culture="neutral" />         <bindingredirect oldversion="0.0.0.0-3.5.0.2" newversion="3.5.0.2" />       </dependentassembly>       </assemblybinding>      </runtime>      </configuration>

i looked configuration of tracing , tested entries web.config proposed e.g.here, here , read documentation.

as written in documentation, windows 8 on, need privileged rights in order trace, changed application pool identity, without success though (the service runs on win 2012 r2 server).

what missing in order enable , use tracing? thank in advance efforts!

you need 2 sections in web.config, 1 tracelisteners configured , diagnostics section in system.servicemodel.

system.diagnostics

add following section:

<system.diagnostics>   <sources>       <source name="system.servicemodel.messagelogging">         <listeners>                  <add name="messages"                  type="system.diagnostics.xmlwritertracelistener"                  initializedata="c:\temp\messages.svclog" />           </listeners>       </source>       <source name="system.servicemodel" switchvalue="information,activitytracing"     propagateactivity="true">         <listeners>               <add name="tracing"                  type="system.diagnostics.xmlwritertracelistener"                  initializedata="c:\temp\tracing.svclog" />         </listeners>       </source>     </sources> </system.diagnostics>

notice value of initializedata , make sure add path there application identity can write. system wide tempfolder should option.

system.servicemodel diagniostics

adapt system.servicemodel nd add diagnostics settings

<system.servicemodel>   <diagnostics>     <messagelogging           logentiremessage="true"           logmalformedmessages="true"          logmessagesatservicelevel="true"           logmessagesattransportlevel="true"          maxmessagestolog="3000"          maxsizeofmessagetolog="2000"/>   </diagnostics>   <!-- other stuff here --> </system.servicemodel>

test settings

with above config logifiles should created , tracing.scvlog should show entries when service started or when request wsdl service. holds exceptions , stacktraces occur.

Google AdWords and AdSense - A Dynamic Small Business Marketing Duo

Unless you have been living under a rock for the last year or so, you probably know that Google has become the king of the search engine hill. There are many reasons for this but number one in my opinion is that above all else they put value on content. Today I want to introduce you to two very powerful small business advertising options created by Google. These two ingenious programs have all but revolutionized the way advertising is done on the web. Warning: If you are thinking..."web advertising isn't for me, I just need a few more clients around the block"...you better read this or be prepared to have your competitors eat your lunch. Goolge AdSense - Again content is king at Google. This program allows web site "publishers" to add some code from Google and receive "content relevant" ads on their site from other site owners. Here is an example - those ads in the box on the right of the page are delivered by Google and are matched to the content
