.NET agent release notesRSS

New Features

• Async Mode: Added automatic Browser Monitoring support.

Fixes

• Async mode: Fixed a bug where using HttpClient with a BaseAddress would result in transactions being lost or corrupted.

Upgrading

• For upgrade instructions, see Upgrade the .NET agent.
• If you are upgrading from a particularly old agent, see Upgrading legacy .NET agents for a list of major changes to the .NET agent.

New Features

• Async mode: The .NET agent now has an optional async mode which provides a look at the agent's asynchronous framework instrumentation as it becomes available. As of this release, asynchronous instrumentation for System.Net.Http.HttpClient and System.Net.HttpWebRequest are available when the agent is in async mode. Please note that activating async mode disables some functionality within the .NET agent. More details and instructions are available here: https://docs.newrelic.com/docs/agents/net-agent/features/async-mode-net

Improvements

• Added new log for cases where the .NET Agent cannot inject Browser Agent

Fixes

• Fixes an issue where intermittent connection issues would cause the Agent to shut down until the process was restarted.

Upgrading

• For upgrade instructions, see Upgrade the .NET agent.
• If you are upgrading from a particularly old agent, see Upgrading legacy .NET agents for a list of major changes to the .NET agent.

Fixes

• Fixed a bug where IIS applications using a classic pipeline app pool would sometimes not report transactions.
• Fixed a bug where clicking on the transaction name from an error trace would not take you to the correct transaction page.
• Fixed an Agent API bug that caused the IgnoreApdex to not actually ignore a transaction for apdex calculations.
• Fixed a bug that would sometimes cause transaction data to be lost if the Cross Application Tracing feature was enabled.
• Fixed a bug that sometimes caused agent environment info to be incomplete.
• Fixed a bug where configuring the agent to ignore HTTP sub-status codes (such as 403.1) would result in an exception.

Upgrading

• If you are upgrading from a particularly old agent, see Upgrading legacy .NET agents for a list of major changes to the .NET agent.

Fixes

• Fixes an issue where if a customer was using the default proxy and not specifying one in the New Relic configuration for the Agent the default would not be used potentially causing HTTP status code 504 to be thrown when communicating with the New Relic collectors.
• Fixes an issue where cross application tracing would slow down in environments using WFC with extremely high throughput.

Upgrading

• For upgrade instructions, see Upgrade the .NET agent.
• If you are upgrading from a particularly old agent, see Upgrading legacy .NET agents for a list of major changes to the .NET agent.

Fixes

• Fixes a bug where the .NET Agent was not handling exceptions coming from HttpRequest.Path and HttpRequest.Url properties. Because the exception was unhandled users would see a System.Web.HttprequestValidationException in their log files and in some cases could miss transactions being reported.
• Fixes a bug where the .NET Agent was throwing null reference exceptions when tracing some SQL commands where there was no transaction available.
• Fixes a bug where the .NET Agent was reporting StackExchange.Redis call times incorrectly. Now, the agent reports the correct call times for apps that use StackExchange.Redis synchronously.

Upgrading

• For upgrade instructions, see Upgrade the .NET agent.
• If you are upgrading from a particularly old agent, see Upgrading legacy .NET agents for a list of major changes to the .NET agent.

Fixes

• Fixed a bug that caused certain frameworks (such as EpiServer CMS) to throw exceptions when trying to resolve a reference to JetBrains.
• Fixed a bug that caused ASMX web service exceptions to not be noticed. This would result in missing some error details, such as stack traces.
• Fixed a bug where sometimes transactions will not be reported if the HttpClient class is used during that transaction.

Upgrading

• For upgrade instructions, see Upgrade the .NET agent.
• If you are upgrading from a particularly old agent, see Upgrading legacy .NET agents for a list of major changes to the .NET agent.

Fixes

• Fixed a bug that prevented self-hosted WCF applications from automatically creating Traced Errors.

Upgrading

• For upgrade instructions, see Upgrade the .NET agent.
• If you are upgrading from a particularly old agent, see Upgrading legacy .NET agents for a list of major changes to the .NET agent.

New Features

• Added StackExchange.Redis framework support. The .Net agent now records time spent making StackExchange.Redis API calls, which will appear as Datastore metrics and Transaction Trace segments in New Relic APM.

Fixes

• Fixed a bug that cause Automatic Browser Monitoring to cause problems on web pages that have no HEAD tag and also contain the text "<BODY" inside of an inline script.
• Improved agent error reporting for applications using WebAPI v1 in unsupported configurations. A warning will be displayed in the agent log (during agent startup) if an application is using an unsupported configuration.
• Azure KUDU (scm) sites were being instrumented by the .NET Agent due to a change in the way Azure is naming application pools. We have updated our logic to match the new application pool naming so these sites will be ignored by the agent.

Upgrading

• For upgrade instructions, see Upgrade the .NET agent.
• If you are upgrading from a particularly old agent, see Upgrading legacy .NET agents for a list of major changes to the .NET agent.

New Features

• Added ServiceStack.Redis v3.x and v4.x framework support. The .Net agent now wraps time spent making ServiceStack.Redis API calls, which will appear as Datastore metrics and Transaction Trace segments in New Relic APM.

Fixes

• Fixed a bug that caused web transaction data to be lost if the request contained an invalid "Referer" HTTP header.
