.NET Agent (legacy) Release Notes
AppOptics agents are no longer receiving updates. The new SolarWinds Observability Libraries can send APM data to AppOptics and are regularly updated with new features and improvements. If your components are supported by the new libraries, consider transitioning to the SolarWinds Observability Libraries for your APM needs. Alternatively, you can also consider using SolarWinds Observability as your primary APM monitoring solution.
SolarWinds Observability Libraries are not compatible with AppOptics agents. Do not use a mix of SolarWinds Observability Libraries and AppOptics agents to instrument applications that are part of a distributed trace.
