Summary

  • Update AppLens public-cloud conversational diagnostics SignalR URL from https://diagnosticschat.azure.com/chatHub to https://diagnosticschatnext.azure.com/chathub (Update AppLens Tool endpoint #3164).
  • Leave China and US Government cloud endpoints unchanged.
  • Add changelog entry under Bugs Fixed.

Test plan

  • dotnet build tools/Azure.Mcp.Tools.AppLens/src
  • dotnet test AppLens unit tests (27 passed)
  • Manual/live smoke: azmcp applens resource diagnose against a diagnosable Azure resource to confirm SignalR connects via the new hub

Fixes #3164

Made with Cursor

Point public-cloud conversational diagnostics at the replacement hub so diagnose continues to work after the old chatHub retirement (microsoft#3164).
