.NET agent v8.6.45.0

Download URLs

Download the appropriate release for your New Relic .NET agent:

https://download.newrelic.com/dot_net_agent/latest_release

New Features

  • Distributed tracing lets you see the path that a request takes as it travels through your distributed system. By showing the distributed activity through a unified view, you can troubleshoot and understand a complex system better than ever before. Distributed tracing is available with an APM Pro or equivalent subscription. To see a complete distributed trace, you need to enable the feature on a set of neighboring services. Enabling distributed tracing changes the behavior of some New Relic features, so carefully consult the transition guide before you enable this feature.
  • To enable distributed tracing, see .NET Agent configuration.

New Features

  • SQL query parameter values can now be captured on Slow SQL Traces. This feature can be enabled with the new configuration option datastoreTracer.queryParameters. The transactionTracer.record_sql configuration option must also be set to raw. See documentation here. This feature should be used with caution as it can lead to the capture of sensitive data. High-security mode prevents the use of this feature. Windows support only. Linux support coming soon.
  • [.NET Framework] Adds support for tracking async transactions when .ConfigureAwait(false) is used from async controller actions in ASP.NET MVC applications.
  • [.NET Core] Adds support for .NET Core 2.1. Support for .NET Core 2.1 requires at least CLR version 2.1.3 and tiered compilation must not be enabled.

Fixes

  • [.NET Core] Fixes issue where status code based errors would be reported instead of the actual noticed Exception. This most commonly occurred with errors noticed in the ExceptionHandlerMiddleware (app.UseExceptionHandler(...)).
  • Fixes an issue where only the first request parameter is captured when request.parameters.* attributes are added to an include list.
