# Orchard Core Content Fields - Prompt Templates

## Add and Configure Content Fields

You are an Orchard Core expert. Generate migration code and recipes for adding content fields with all available settings.

### Guidelines

- Fields are added to content parts using `AlterPartDefinitionAsync` in a migration.
- Each field has a `FieldSettings` base with `Hint` (string) and `Required` (bool).
- Each field type has its own specific settings class (e.g., `TextFieldSettings`, `NumericFieldSettings`).
- Fields also have `ContentPartFieldSettings` controlling `DisplayName`, `Description`, `Editor`, `DisplayMode`, and `Position`.
- Use `.WithEditor("EditorName")` to select an editor variant.
- Use `.WithDisplayMode("DisplayModeName")` to select a display variant.
- Third-party modules providing fields (CrestApps, Lombiq, community modules, etc.) must be installed as NuGet packages in the web project (the startup project of the solution), not just in the module project.
- Always seal classes.

### General Pattern for Adding a Field

```csharp
await _contentDefinitionManager.AlterPartDefinitionAsync("{{PartName}}", part => part
    .WithField("{{FieldName}}", field => field
        .OfType("{{FieldType}}")
        .WithDisplayName("{{DisplayName}}")
        .WithDescription("{{Description}}")
        .WithPosition("{{Position}}")
        .WithSettings(new {{FieldType}}Settings
        {
            // Field-specific settings
        })
    )
);
```

## Installing Third-Party Field Modules

Modules that provide custom fields from external sources (community or third-party modules) must be installed as NuGet packages in the **web project** (the startup project of the solution):

```xml
<Project Sdk="Microsoft.NET.Sdk.Web">
  <ItemGroup>
    <!-- Orchard Core base -->
    <PackageReference Include="OrchardCore.Application.Cms.Targets" Version="2.*" />

    <!-- Third-party modules must be added to the web project -->
    <PackageReference Include="Lombiq.HelpfulExtensions.OrchardCore" Version="1.*" />
  </ItemGroup>
</Project>
```

For local project references to third-party modules:

```xml
<ItemGroup>
  <!-- Local third-party module project reference in the web project -->
  <ProjectReference Include="../ThirdParty.Module/ThirdParty.Module.csproj" />
</ItemGroup>
```
