A user turn produced by the chat input: the typed text plus any images the user attached (roadmap \#13 — multimodal input). Used as the payload of `ChatInput.OnSend` so text-only and multimodal turns travel through the same callback.

## Definition

Namespace: `Novior.MentorAgent.Abstractions.Models`. Package: `Novior.MentorAgent.Abstractions`.

`public sealed record MentorUserMessage : IEquatable<MentorUserMessage>`

```shell
dotnet add package Novior.MentorAgent.Abstractions
```

## Constructors

`public MentorUserMessage(string Text, IReadOnlyList<MentorAttachment>? Attachments = null)`

A user turn produced by the chat input: the typed text plus any images the user attached (roadmap \#13 — multimodal input). Used as the payload of `ChatInput.OnSend` so text-only and multimodal turns travel through the same callback.

**Parameters**

- `Text`: The typed message. Never null; may be whitespace only when images are attached.
- `Attachments`: Attached images, or `null` for a text-only turn.

## Properties

### `Attachments`

`public IReadOnlyList<MentorAttachment>? Attachments { get; init; }`

Attached images, or `null` for a text-only turn.

### `HasAttachments`

`public bool HasAttachments { get; }`

True when at least one image is attached.

### `Language`

`public MentorLanguage? Language { get; init; }`

The language of this turn: what the assistant answers in, and the language of the texts the server writes for it. `null` means `MentorOptions.Language`, read again on every turn. `ChatWidget` sets it from its `Language` parameter.

On the wire it is the name (`"Italian"`) or the ISO code (`"it"`), in any case. Any other value — a number, a name that is not a [`MentorLanguage`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentorlanguage), an empty string — is read as `null`.

### `Text`

`public string Text { get; init; }`

The typed message. Never null; may be whitespace only when images are attached.
