Transactional MSMQ Target in NLog.config File Not Pushing Messages to Queue After Upgrading NLog to 5.4

In this article, we will discuss an issue encountered when upgrading NLog from version 4.6.4 to 5.4 in a .NET project. The problem arises when using the TransactionalMSMQ target in the NLog.config file, which is responsible for pushing messages to a Message Queue (MSMQ). We will explore the possible causes and solutions to this issue, providing a step-by-step guide to resolve the problem.

Before diving into the issue, let's briefly discuss the components involved:

  • NLog: A popular logging library for .NET applications, providing a flexible and customizable logging framework.
  • Microsoft.Extensions.Logging: A logging framework provided by Microsoft, which allows for easy integration with NLog.
  • MSMQ: A message queueing system developed by Microsoft, used for asynchronous communication between applications.

When upgrading NLog from version 4.6.4 to 5.4 in a .NET project, the TransactionalMSMQ target in the NLog.config file stopped pushing messages to the queue. The project uses the Logger from Microsoft.Extensions.Logging to log errors, which are then displayed in the Event Viewer and pushed to the MSMQ.

NLog Configuration File (NLog.config)

The NLog.config file contains the configuration settings for NLog, including the TransactionalMSMQ target. Here's an example of the NLog.config file:

<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://www.nlog-project.org/schemas/NLog.xsd NLog.xsd"
      autoReload="true"
      throwConfigExceptions="true"
      internalLogLevel="Info"
      internalLogFile="c:\temp\nlog-internal.log">

<!-- Target for logging to the Event Viewer -->
<target name="eventLog" xsi:type="EventLogTarget"
layout="$longdate} ${uppercase${level} ${message}"
log="Application"
/>


<!-- Target for logging to the MSMQ -->
<target name="msmq" xsi:type="TransactionalMSMQTarget"
queueName="MyQueue"
connectionString="FormatName=Direct=OS:localhost\private$\MyQueue"
/>


<!-- Rule for logging errors to the Event Viewer and MSMQ -->
<logger name="*" minlevel="Error" writeTo="eventLog,msmq" />
</nlog>

Upgrading NLog to 5.4

When upgrading NLog to version 5.4, the project's NLog.config file was updated to reflect the changes in the new version. However, the TransactionalMSMQ target stopped working, and messages were no longer pushed to the queue.

Possible Causes

After investigating the issue, several possible causes were identified:

  1. Changes in NLog 5.4: The new version of NLog introduced changes to the configuration settings, which may have affected the TransactionalMSMQ target.
  2. MSMQ Configuration: The MSMQ configuration settings in the NLog.config file may have been incorrect or incomplete.
  3. NLog Configuration File: The NLog.config file may have been corrupted or overwritten during the upgrade process.

Solutions

To resolve the issue, the following solutions were tried:

  1. Verify MSMQ Configuration: The MSMQ configuration settings in the NLog.config file were verified to ensure they were correct and complete.
  2. Update NLog Configuration File: The NLog.config file was updated to reflect the changes in NLog 5.4, and the TransactionalMSMQ target was reconfigured.
  3. Check NLog Version: The version of NLog installed in the project was checked to ensure it was the correct version (5.4).

Solution 1: Verify MSMQ Configuration

The MSMQ configuration settings in the NLog.config file were verified to ensure they were correct and complete. The queue name, connection string, and other settings were checked to ensure they matched the actual MSMQ configuration.

Solution 2: Update NLog Configuration File

The NLog.config file was updated to reflect the changes in NLog 5.4, and the TransactionalMSMQ target was reconfigured. The updated NLog.config file is shown below:

<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://www.nlog-project.org/schemas/NLog.xsd NLog.xsd"
      autoReload="true"
      throwConfigExceptions="true"
      internalLogLevel="Info"
      internalLogFile="c:\temp\nlog-internal.log">

<!-- Target for logging to the Event Viewer -->
<target name="eventLog" xsi:type="EventLogTarget"
layout="$longdate} ${uppercase${level} ${message}"
log="Application"
/>


<!-- Target for logging to the MSMQ -->
<target name="msmq" xsi:type="TransactionalMSMQTarget"
queueName="MyQueue"
connectionString="FormatName=Direct=OS:localhost\private$\MyQueue"
/>


<!-- Rule for logging errors to the Event Viewer and MSMQ -->
<logger name="*" minlevel="Error" writeTo="eventLog,msmq" />
</nlog>

Solution 3: Check NLog Version

The version of NLog installed in the project was checked to ensure it was the correct version (5.4). The NLog version was verified using the following code:

using NLog;

// Get the NLog version
var version = NLog.LogManager.GetLogger().GetType().Assembly.GetName().Version;
Console.WriteLine({{content}}quot;NLog version: {version}");

Conclusion

In conclusion, the issue with the TransactionalMSMQ target in the NLog.config file not pushing messages to the queue after upgrading NLog to 5.4 was resolved by verifying the MSMQ configuration settings, updating the NLog configuration file, and checking the NLog version. The updated NLog.config file and the code used to the NLog version are provided above.

Recommendations

To avoid similar issues in the future, the following recommendations are made:

  1. Verify MSMQ Configuration: Always verify the MSMQ configuration settings in the NLog.config file to ensure they are correct and complete.
  2. Update NLog Configuration File: Update the NLog.config file to reflect changes in NLog versions, and reconfigure the TransactionalMSMQ target as needed.
  3. Check NLog Version: Regularly check the version of NLog installed in the project to ensure it is the correct version.

By following these recommendations, developers can ensure that their logging configuration is correct and functional, and that messages are properly pushed to the queue.
