.NET agent release notesRSS

New Features

• Async mode: Custom instrumentation is now supported for both synchronous and asynchronous methods when async mode is enabled, however; the metricName and transactionNamePriority elements will not be respected. This is coming in a future release. Please see our custom instrumentation documentation for details.

Fixes

• Changes the log messages for when a wrapper / method combination needs to be shut down. The new message provides more information and clarity around the shutdown event.

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: Added support for SqlCommand method ExecuteReaderAsync, ExecuteScalarAsync, ExecuteNonQueryAsync, and ExecuteXmlReaderAsync.
• Async Mode: Added support for SQL Traces on slow SQL commands when the agent is in async mode.
• Async mode: Adds support for synthetic transaction tracing when the agent is in async mode.
• Async Mode: Added instrumentation for System.Data.SqlClient.SqlDataReader ReadAsync and NextResultAsync methods. Note that, for performance reasons, this instrumentation is disabled by default in the SqlAsync instrumentation xml file.

Fixes

• Fixed a bug where the agent erroneously treated HTTP headers as being case-sensitive, causing CAT to not work under certain conditions.
• Fixed a bug where the agent rejected custom events if any attribute had a null value.
• Async mode: Fixed a bug that caused some datastore activity to be missed.

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

• 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 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.
