In addition to enabling workflows to call methods on the host process, WF enables you to handle events that are raised in the host process, inside the workflow instance.
WF enables you to generate strictly bound activities to interact with methods on the host process in the same way that you create strictly bound controls. Strictly bound activities enable you to add activities to your workflow that are already configured to a specific host process event.
Windows Workflow Foundation (WF) enables you to integrate your workflow solutions seamlessly into applications that are based on the Windows operating system. The ability of the workflow to call methods in the host process and then to handle events from the host process to control execution flow is functionality that is often required.
When you monitor activities in a distributed application, it can be difficult to correlate events on various machines, such as the correct sequence in which activities occurred and which activity caused a subsequent one to occur. WCF provides a solution that has a built-in correlation mechanism, which you can enable by doing the following:
You can define your own application-specific or service-specific activities that you want to trace. To do this, you define a TraceSource in your code and pass a name for the source. You can then use this source name in your WCF configuration file and add a trace listener to it.
WCF provides functionality that enables you to monitor the activities that your services and client applications perform when they run. Tracing is not enabled by default. To activate tracing, you must create a trace listener and set a trace level other than Off for the selected trace source in your configuration

To generate useful diagnostic information to debug a problem in your WCF solution, you must match the level of detail and the amount of coverage to the problem at hand.
To enable your WCF service or WCF client application to log messages, you must add the necessary configuration elements to the WCF configuration of your application. The following WCF configuration example shows how you can configure message logging in its simplest form
