WCF

WCF Trace ServiceLevelReceiveReply body is ...

Chilberto — Wed, 09 Jan 2008 18:28:58 GMT

If the WCF binding is using streaming, the body of the trace record will be recorded as "...". This is true for the Oracle LOB Adapters.

For Example:

</System>

<s:Envelope xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope">

<s:Header>

<a:Action s:mustUnderstand="1">http://Microsoft.LobServices.OracleDB/2007/03/ADMIN/Package/Example/response</a:Action>

</s:Header>

<s:Body>...</s:Body>

</s:Envelope>

</MessageLogTraceRecord>

</DataItem>

</TraceData>

</ApplicationData>

</E2ETraceEvent>

Enterprise Library Policy Injection Application Block example

I have created an example using Enterprise Library's Policy Injection application block. In this example, I am applying an event log trace to a WCF host using a named pipe binding.

WCF Trace Viewer: Filtering

The amount of traces generated by WCF (System.ServiceModel and System.ServiceModel.MessageLogging) can be overwhelming at first glance. Here is a short post about some the features. A more detailed description can be viewed at MSDN Service Trace Viewer.

WCF BAM Interceptors and primaryImportConnectionString

Chilberto — Fri, 24 Aug 2007 20:50:05 GMT

When trying to get the example in Instrumenting the WCF Getting Started Sample (BizTalk Server Sample) to run, I encountered the following error:

Server Error in '/servicemodelsamples' Application.

Configuration Error

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: Unrecognized attribute 'primaryImportConnectionString'. Note that attribute names are case-sensitive.

Source Error:


            Line 50:       <endpointBehaviors>
Line 51:         <behavior name="bamBehavior">
Line 52: 			<BamBehaviorExtension primaryImportConnectionString=
"Integrated Security=SSPI;Data Source=.;Initial Catalog=BAMPrimaryImport;" PollingIntervalSec="1500"  >
Line 53: 			 </BamBehaviorExtension>
Line 54:

Source File: f:\inetpub\wwwroot\servicemodelsamples\web.config Line: 52

Version Information: Microsoft .NET Framework Version:2.0.50727.42; ASP.NET Version:2.0.50727.42

After using Lutz Roeder's Reflector, I was able to determine that the configuration should be changed to:

<behavior name="bamBehavior">
    <BamEndpointBehaviorExtension 
        ConnectionString="Integrated Security=SSPI;Data Source=.;Initial Catalog=BAMPrimaryImport;"
        PollingIntervalSec="1500" />
  </behavior>

I could not find a mention of this in Google, so hopefully this will save someone some time out there.

WCF Service Trace Viewer

Chilberto — Tue, 07 Aug 2007 21:29:48 GMT

The Service Trace Viewer provides a way of viewing the activity of WCF hosts and clients. This utility is available in the Windows SDK for Framework 3.0.

If you are not familiar with the SvcTraceViewer application, I created an introduction based on a trace of the Simple Header Example created in an earlier post.
