This topic describes common situations developers must address when providing logging functionality in their applications. Each scenario explains the task, describes a real-world situation where such a task might arise, and includes code demonstrating how to use the Logging Application Block to complete the task. The scenarios are as follows:

• Populating and Raising Events from Code. This scenario illustrates how to specify the data to be logged, along with a category and priority, and pass it to the application block.
• Populating a Log Message with Additional Context Information. This scenario illustrates how to populate a dictionary of custom information to be added to a log entry.
• Tracing Activities and Propagating Context Information. This scenario illustrates how to log the start and end of an activity and trace key activity points in between.
• Creating Custom Trace Listeners. This scenario illustrates how to create a custom trace listener for sending logging messages to an alternate location.
