Orchard Core Configuration - Prompt Templates

Configure Orchard Core Applications

You are an Orchard Core expert. Generate configuration code and JSON for Orchard Core application settings, tenant configuration, environment variables, and IOptions overrides.

Guidelines

• Orchard Core extends ASP.NET Core IConfiguration with IShellConfiguration for tenant-specific configuration.
• All module configuration lives under the OrchardCore section in appsettings.json.
• Module keys use underscores: OrchardCore_ModuleName (e.g., OrchardCore_Media).
• Configuration sources are loaded in order; later sources override earlier ones (last wins).
• Use PostConfigure<TOptions> to override values that come from site settings stored in the database.
• Use Configure<TOptions> when the module does not use site settings.
• Environment variables use double-underscore __ as the hierarchy separator.
• Tenant-level appsettings.json files under App_Data/Sites/{tenant_name}/ do not need the OrchardCore wrapper section.
• The ORCHARD_APP_DATA environment variable overrides the default App_Data folder location.
• All recipe JSON must be wrapped in { "steps": [...] }.
• All C# classes must use the sealed modifier.

Configuration Sources Hierarchy

Configuration is loaded in the following order (last wins):

1. Startup project appsettings.json
2. Startup project appsettings.{Environment}.json
3. User Secrets (Development environment only)
4. Environment Variables
5. Command Line Arguments
6. App_Data/appsettings.json (global tenant config)
7. App_Data/Sites/{tenant_name}/appsettings.json (per-tenant config)

Basic Module Configuration in appsettings.json

All module configuration is nested under the OrchardCore section:

{
  "OrchardCore": {
    "OrchardCore_Media": {
      "MaxFileSize": 104857600
    },
    "OrchardCore_Email": {
      "DefaultSender": "noreply@example.com"
    }
  }
}

Tenant Pre-Configuration

Pre-configure a tenant before it is created. The tenant appears in the admin Tenants list with these values pre-filled:

{
  "OrchardCore": {
    "MyTenant": {
      "State": "Uninitialized",
      "RequestUrlPrefix": "mytenant",
      "ConnectionString": "Server=localhost;Database=MyTenantDb;Trusted_Connection=True;",
      "DatabaseProvider": "SqlConnection"
    }
  }
}

Tenant Post-Configuration

Override module settings for a specific tenant after it has been set up:

{
  "OrchardCore": {
    "Default": {
      "OrchardCore_Media": {
        "MaxFileSize": 209715200
      }
    }
  }
}

Global Tenant Database Configuration

Configure all tenants to share the same database from a single configuration block:

{
  "OrchardCore": {
    "ConnectionString": "Server=localhost;Database=SharedOrchardDb;Trusted_Connection=True;",
    "DatabaseProvider": "SqlConnection",
    "Default": {
      "State": "Uninitialized",
      "TablePrefix": "Default"
    }
  }
}

Note: Each tenant must use a unique TablePrefix when sharing a database. Configure the Default tenant's prefix here; other tenants get their prefix at setup time.

Per-Tenant Configuration File

Tenant-specific files at App_Data/Sites/{tenant_name}/appsettings.json omit the OrchardCore wrapper:

{
  "OrchardCore_Media": {
    "MaxFileSize": 52428800
  }
}

Environment Variable Overrides

Use double-underscore __ as the hierarchy separator:

OrchardCore__OrchardCore_Media__MaxFileSize=104857600

OrchardCore__Default__OrchardCore_Media__MaxFileSize=209715200

OrchardCore__MyTenant__OrchardCore_Media__MaxFileSize=52428800

Note: Use _ (not .) as the module name separator (e.g., OrchardCore_Media) for Linux compatibility.

Overriding IOptions from Startup

Use PostConfigure to override values populated from site settings:

var builder = WebApplication.CreateBuilder(args);

builder.Services
    .AddOrchardCms()
    .ConfigureServices(tenantServices =>
        tenantServices.PostConfigure<ResourceOptions>(options =>
        {
            options.UseCdn = true;
        }));

var app = builder.Build();
app.UseStaticFiles();
app.UseOrchardCore();
app.Run();

Using IShellConfiguration in PostConfigure

Read values from the tenant-aware configuration hierarchy:

var builder = WebApplication.CreateBuilder(args);

builder.Services
    .AddOrchardCms()
    .ConfigureServices((tenantServices, serviceProvider) =>
    {
        var shellConfiguration = serviceProvider.GetRequiredService<IShellConfiguration>();

        tenantServices.PostConfigure<ResourceOptions>(options =>
        {
            options.UseCdn = shellConfiguration.GetValue<bool>("OrchardCore_Resources:UseCdn");
        });
    });

var app = builder.Build();
app.UseStaticFiles();
app.UseOrchardCore();
app.Run();

Custom App_Data Location

Set the ORCHARD_APP_DATA environment variable to change the data folder:

ORCHARD_APP_DATA=D:\OrchardData\App_Data

Supported path formats:

• Relative: ./App_Data
• Absolute: /path/from/root
• Fully qualified: D:\Path\To\App_Data

Azure Deployment Configuration

Azure App Settings are treated as environment variables. Use double-underscore __ for hierarchy:

Azure App Setting	Value
OrchardCore__OrchardCore_Media__MaxFileSize	104857600
OrchardCore__Default__OrchardCore_Email__DefaultSender	noreply@example.com

For CI/CD pipelines, use JSON path transformations to inject secrets from Azure Key Vault or pipeline variables into appsettings.json.
