Domain

Baked introduces a model generation mechanism to reflect the business domain of a project. The generated model instance can be used directly in layers or in features while configuring configuration targets.

app.Layers.AddDomain();

Configuration Targets

This layer provides IDomainTypeCollection and DomainModelBuilderOptions configuration targets for building DomainModel in Generate mode. It also provides DomainServiceCollection configuration target for features to add DomainServiceDescriptor for domain types which then be used to generate an IServiceAdder implementation. The generated IServiceAdder is then used in Start mode for auto registering domain types to service collection.

IDomainTypeCollection

This target is provided in AddDomainTypes phase. To configure it in a feature;

configurator.ConfigureDomainTypeCollection(types =>
{
    ...
});

DomainModelBuilderOptions

This target exposes options for configuring built-in DomainModelBuilder and is provided in AddDomainTypes phase. To configure it in a feature;

configurator.ConfigureDomainModelBuilder(builder =>
{
    ...
});

DomainServiceCollection

This target is provided in GenerateCode phase and it is used to generated IServiceAdder to add domain services during AddService phase in Start mode. To configure it in a feature;

configurator.ConfigureDomainServiceCollection((services, domain) =>
{
    // use domain metadata to register services at generate time
    ...
});

Phases

This layer introduces following Generate phases to the application it is added;

• AddDomainTypes: This phase adds an IDomainTypeCollection instance to the application context
• BuildDomainModel: This phase uses domain types to build and add a DomainModel instance to the application context

To access the domain model from a feature use below extension method;

configurator.UsingDomainModel(domain =>
{
    // use domain metadata to configure any configuration target
    ...
});

Proxifying Entities

It is possible to avoid adding protected virtual and default constructors to classes (such as entity classes) to enable lazy loading and dynamic proxy.

Please add below references to your projects that contain your domain objects (projects that depend only to Baked.Abstractions).

<ItemGroup>
  <PackageReference Include="EmptyConstructor.Fody" PrivateAssets="All" />
  <PackageReference Include="Fody" PrivateAssets="All" />
  <PackageReference Include="Publicize.Fody" PrivateAssets="All" />
  <PackageReference Include="Virtuosity.Fody" PrivateAssets="All" />
</ItemGroup>

Add versions to Directory.Packages.props;

<PackageVersion Include="EmptyConstructor.Fody" Version="..." />
<PackageVersion Include="Fody" Version="..." />
<PackageVersion Include="Publicize.Fody" Version="..." />
<PackageVersion Include="Virtuosity.Fody" Version="..." />

Build your project now. Expect a build fail on your first build after you add fody. This fail adds FodyWeavers.xml to your project. Following builds will success.
