[jsquire]

Summary

A new analyzer has been added which detects missing model factory methods. The language libraries are being flagged for:

Azure.AI.Language.Text

• AnalyzeTextResult

Azure.AI.Language.Conversations

• AnalyzeConversationActionResult

Scope of work

• Investigate flagged types and ensure the model factory has the needed methods.
• If a type is being inappropriately flagged, add a local suppression in that type.
• Remove the warning suppression for AZC0035 in the project file.
