New Features

CancellationToken Support

  • All async methods now accept optional CancellationToken parameters (fully backwards-compatible)

Targeted Messages (Preview) - ExperimentalTeamsTargeted

  • Send messages visible only to specific recipients: activity.WithRecipient(account, isTargeted: true)

Reactions (Preview) - ExperimentalTeamsReactions

  • New ReactionClient for bot-to-user reactions with expanded reaction types

Sign-in Failure Handling

  • New signin/failure invoke handling with actionable logging via app.OnSignInFailure()

Breaking Changes

  1. GetParticipantAsync - Now requires tenantId parameter
  2. MeetingParticipant - Model restructured (removed Id, Role, IsOrganizer, JoinTime; added Meeting, Conversation)
  3. App.Id - Now nullable
  4. Activity.Value - Refactored for proper type hierarchy access

Deprecations

  • Teams Controllers - Marked [Obsolete], migrate to Minimal APIs (see Deprecated.Controllers sample)
  • Handlers without CancellationToken - Marked [Obsolete], update handler signatures
  • MessageReactionActivity.AddReaction()/.RemoveReaction() - Marked [Obsolete], use ReactionClient instead

Fixes

  • Meeting activity deserialization for Teams PascalCase payloads
  • UserAgent version accuracy
  • GetParticipantAsync signature and data structure

Updates

  • Package: System.IdentityModel.Tokens.Jwt v8.16.0
  • Samples: Updated to Minimal APIs and Local environment
  • New Samples: Reactions, TargetedMessages, Deprecated.Controllers

Before (Obsolete):

teams.OnMessage(async (context) => { ... });

After:

teams.OnMessage(async (context, cancellationToken) => { ... });

Targeted Messages:

Before:

activity.WithTargetedRecipient(userId);

After:

activity.WithRecipient(account, isTargeted: true);

Reactions:
