What's New in PostSharp 6.1

In PostSharp 6.1, we primarily focused on two directions: the logging API so that we can cope with distributed systems, and the debugging experience. Additionally, we fixed gapped in .NET Standard and C# 7.3 support.


Despite being a minor version, PostSharp 6.1 contains some low-impact breaking changes in the logging API. The chances that you would be negatively affected are minor. See Breaking Changes in PostSharp 6.1 for details.

Logging: major improvements in the front-end API

We've worked hard to improve the scenario of logging high-load distributed systems (such microservices) into a structured database (such as Elastic Search), and enable statistical processing of the log records.

To achieve this goal, we had to bring several improvements to PostSharp Logging:

  • Semantic-First Logging, suitable for statistical processing of messages and machine learning. See semantic for details.

  • Custom Properties on custom messages and activities, including cross-process properties (aka baggage). See Adding Properties to Messages and Activities for details.

  • Hierarchical and Cross-Process Activity ID that can be easily filtered and sorted on to get a logical view of a request in a distributed system. See Logging in a Distributed System for details.

  • Sampled Logging: Instead of hoarding gigabytes of useless logs, you can now enable logging for selected requests only. See Adjusting Logging Verbosity for details.

  • Execution time measurement for custom activities. See execution-time for details.

  • Serilog backend improvements: You now have more control over generated Serilog properties. See IncludedSpecialProperties and LogEventEnricher properties for details.

  • Application Insights backend improvements: the backend now supports custom properties. See ApplicationInsightsLoggingBackendOptions class for details.

Additionally, PostSharp 6.1 brings the following improvements to logging:

  • We are now using the type name instead of the role name by default to read the logging level from the backend.

  • Simplified API to set up verbosity. See DefaultVerbosity for details.

  • Exception logging is now again implemented in a catch block instead of an exception filter block.

  • Exception formatting can now be customized by setting the ExceptionFormatter property.

Visual Studio debugger: better support for async methods

We are releasing a complete refactoring of our add-in to the Visual Studio debugger. It solves a dozen of issues and finally fixes the debugging behavior of intercepted async methods.

Support for C# 7.3

PostSharp was affected by the following features of C# 7.3:

Fixing gaps in platform support

  • PostSharp.Patterns.Caching now supports .NET Standard 2.0 and .NET Framework 4.5.

  • PostSharp.Patterns.Diagnostics.Backends.CommonLogging now supports .NET Standard 2.0.
