We are working on pipeline agent migration to .NET 6. One of the side effect of this migration is that the legacy HTTP handler will be no longer available for use due to changes in the .NET runtime itself.
Thus the related agent knob will not work once the migration will be completed. We recommend stopping using the AZP_AGENT_USE_LEGACY_HTTP knob.
The cross-platform build and release agent for Azure Pipelines and Team Foundation Server 2015 and beyond. This replaced the deprecated closed source windows build agent and the previous cross-platform agent.
Supported on Windows, macOS, and several Linux flavors. Written for .NET Core in C#.

This agent can be used for both Azure Pipelines and Azure DevOps Server (Team Foundation Server). Support is extended to all on-premise solutions based on their lifecycle (including extended support).
The only exception is the Windows version of the agent for TFS 2015 since it is distributed along with a separate Node-based agent.
Releases have labels Latest and Pre-release. Please make a note that the labels mean:
- Latest - release process of the agent version is fully completed and it's available for all users;
- Pre-release - release process of the agent version was started and it's already available for using by part of users.
Each new version of agent is released for users by groups during several days. And usually it becomes available for all users within 6-8 days after start of release. The release has label "Pre-release" during all these days. So it's expected behavior if specific release is used by builds in pipelines but it's marked as "Pre-release".
