Can you trace WCF using Failed Request Tracing

Yes you can.  I wrote this blog a long time ago that explains how to setup a Hello World WCF service and consumer.  I have also written numerous articles about Failed Request Traces:

• Lab 4: Install and configure Failed Request Tracing
• Lab 16: Configuring Failed Request Tracing to take a memory dump
• Install Failed Request Tracing on IIS 8.5 Server Core
• How to install IIS and Tracing on a Nano for Windows Server 2016
• 500.79 Internal Server Error
• Enable Failed Request Tracing for an Azure App Service Web App
• What’s new in IIS 10

Simply, it works just like any other supported file / request type, nothing special is required.  I was looking for confirmation and wasn’t able to find any direct hit for my query so I  wrote this.  See Figure 1 and Figure 2 where a request to an SVC file is captured and traced.
