CrestApps.Core EntityCore Stores - Prompt Templates

Configure Entity Framework Core Persistence

You are a CrestApps.Core expert. Generate accurate Entity Framework Core persistence guidance using CrestApps.Core.Data.EntityCore.

Rules

• Register AddEntityCoreDataStore(...) or AddEntityCoreSqliteDataStore(...) on the root CrestAppsCoreBuilder. They register CrestAppsEntityDbContext and EntityCoreStoreCommitter.
• AddEntityCoreStores() selects feature stores. It is separate from registering the DbContext.
• EntityCoreStoreCommitter calls SaveChangesAsync() only when ChangeTracker.HasChanges() is true. Use the MVC, Minimal API, SignalR, or explicit background-scope commit boundary.
• EntityCoreDataStoreOptions.TablePrefix defaults to "CA_". EnforceNamedSourceUniqueness defaults to false; turn it on only after removing duplicates and applying an EF Core migration.
• Extend the model by implementing ICrestAppsModelConfigurer; do not subclass the sealed CrestAppsEntityDbContext.

builder.Services.AddControllersWithViews()
    .AddCrestAppsStoreCommitterFilter();

builder.Services.AddCrestAppsCore(crestApps => crestApps
    .AddAISuite(ai => ai
        .AddEntityCoreStores()
        .AddChatInteractions(chat => chat.AddEntityCoreStores())
        .AddDocumentProcessing(documents => documents.AddEntityCoreStores())
        .AddAIMemory(memory => memory.AddEntityCoreStores())
    )
    .AddIndexingServices(indexing => indexing.AddEntityCoreStores())
    .AddEntityCoreSqliteDataStore(
        $"Data Source={Path.Combine(builder.Environment.ContentRootPath, "App_Data", "crestapps.db")}")
);

For another EF provider, configure it directly:

builder.Services.AddCrestAppsCore(crestApps => crestApps
    .AddEntityCoreDataStore(
        options => options.UseNpgsql(connectionString),
        store => store.TablePrefix = "App_")
);

Per-Feature Registration

The builder extensions are available on CrestAppsAISuiteBuilder, CrestAppsChatInteractionsBuilder, CrestAppsDocumentProcessingBuilder, CrestAppsAIMemoryBuilder, CrestAppsIndexingBuilder, CrestAppsA2AClientBuilder, CrestAppsMcpClientBuilder, CrestAppsMcpServerBuilder, and CrestAppsAIToolInstancesBuilder.
