Model names should use recommended suffixes for C# SDKs.

C# SDK model names should use these recommended suffixes:

• Use Config instead of Options, except for client options.
• Use Content instead of Request.
• Use Result instead of Response.

The rule checks the C#-resolved model name and respects @clientName overrides.

❌ Incorrect

model SearchOptions {
  filter: string;
}

model CreateWidgetRequest {
  name: string;
}

model CreateWidgetResponse {
  id: string;
}

✅ Correct

model SearchConfig {
  filter: string;
}

model CreateWidgetContent {
  name: string;
}

model CreateWidgetResult {
  id: string;
}

Or using @@clientName in client.tsp to override just the C# name:

client.tsp

@@clientName(SearchOptions, "SearchConfig", "csharp");
@@clientName(CreateWidgetRequest, "CreateWidgetContent", "csharp");
@@clientName(CreateWidgetResponse, "CreateWidgetResult", "csharp");
