How to Trace SOAP XML as a Web Service Client in .NET Core

Working with SOAP web services in .NET Core can sometimes feel challenging, especially when trying to track the messages sent and received. Without proper tracing, debugging issues can become time-consuming and frustrating. In this post, we will explore how to trace SOAP XML as a web service client in .NET Core, providing you with a structured approach to implement logging of request and response messages.

The Challenge

When working with SOAP services, it’s essential to have visibility into the XML messages being exchanged. In the .NET Framework, this could be easily handled using the SoapExtensionAttribute, which is not available in .NET Core. This raises the question:

How can we trace SOAP XML messages in .NET Core?

The Solution

To solve this problem in .NET Core, we will create two custom classes that implement interfaces for endpoint behavior and message inspection.

Step 1: Create the Inspector Behavior Class

The first class, InspectorBehavior, will implement the IEndpointBehavior interface, allowing us to modify the behavior of the service endpoint. Below is the implementation:

Step 2: Create the Message Inspector Class

The second class, MyMessageInspector, will implement the IClientMessageInspector interface. This class will handle the actual tracing of the request and response messages:

Step 3: Integrate Tracing in Your Client Call

Once you have these classes implemented, you can integrate the tracing behavior with your SOAP client as follows:

Conclusion

Using the custom classes we created—InspectorBehavior and MyMessageInspector—you can effectively trace the SOAP XML messages being sent and received by your web service client in .NET Core. This approach enhances your ability to debug and understand communication with SOAP services, ultimately leading to more robust applications.

By following these steps, you can implement your own tracing mechanism, ensuring that you always have access to the request and response XML for analysis. Happy coding!
