Corrected grammar from "for which route" to "to which to route".

Suggested change

# Determine which team for which route the ticket.

# Determine to which team to route the ticket.

dotnet/src/Microsoft.Agents.AI.Workflows.Declarative.AzureAI/AzureAgentProvider.cs

 /// <param name="projectCredentials">The credentials used to authenticate with the Foundry project. This must be a valid instance of <see cref="TokenCredential"/>.</param>
-/// <param name="httpClient">An optional <see cref="HttpClient"/> instance to be used for making HTTP requests. If not provided, a default client will be used.</param>
-public sealed class AzureAgentProvider(Uri projectEndpoint, TokenCredential projectCredentials, HttpClient? httpClient = null) : WorkflowAgentProvider
+public sealed class AzureAgentProvider(Uri projectEndpoint, TokenCredential projectCredentials) : WorkflowAgentProvider


Removing the httpClient parameter from the constructor is a breaking change. Consider keeping the parameter with a default value of null to maintain backward compatibility while also supporting the new property-based approach. The current change would break existing code that passes HttpClient through the constructor.
