All Catel.Fody options are configured in FodyWeavers.xml by adding attributes to the <Catel /> element.

<Weavers>
  <Catel WeaveArguments="false" WeaveLogging="false" />
</Weavers>

The sections below describe every available option together with its default value.

WeaveProperties

Weave all regular auto-properties on classes that inherit (directly or indirectly) from Catel.Data.ModelBase into full Catel properties.

Default value: true

<Catel WeaveProperties="false" />

See Weaving properties for details and examples.

WeaveExposedProperties

Weave all Catel properties decorated with both [Model] and [Expose] as automatic ViewModelToModel mappings.

Default value: true

<Catel WeaveExposedProperties="false" />

See Exposing properties on view models for details.

WeaveCalculatedProperties

Automatically raise PropertyChanged notifications for computed (calculated) properties when one of the source properties they reference changes.

For example, given:

public string FirstName { get; set; }
public string LastName { get; set; }
public string FullName => $"{FirstName} {LastName}".Trim();

Catel.Fody will automatically hook up change notifications so that FullName raises PropertyChanged whenever FirstName or LastName changes.

Default value: true

<Catel WeaveCalculatedProperties="false" />

See Computed properties for more information.

WeaveArguments

Weave argument-check attributes on method parameters into actual guard calls at the beginning of the method body.

Default value: true

<Catel WeaveArguments="false" />

See Weaving argument checks for details.

WeaveLogging

Replace calls to LogManager.GetCurrentClassLogger() with the slightly faster LogManager.GetLogger(typeof(ClassName)) form.

Default value: true

<Catel WeaveLogging="false" />

GeneratedPropertyDataAccessibility

Controls the accessibility modifier of the PropertyData fields that Catel.Fody generates. Accepted values are Public, Internal, and Private.

Default value: Public

<!-- Make all generated PropertyData fields internal -->
<Catel GeneratedPropertyDataAccessibility="Internal" />

Example — with the default (Public) accessibility a weaved property looks like:

public static readonly PropertyData NameProperty = RegisterProperty("Name", typeof(string));

With Internal:

internal static readonly PropertyData NameProperty = RegisterProperty("Name", typeof(string));

DisableWarningsForAutoPropertyInitializers

When a property uses a C# auto-property initializer (introduced in C# 6), Catel.Fody emits a warning because the initializer value is moved into the constructor rather than used as the registered default value. Set this to true to suppress those warnings if you are aware of and comfortable with this behavior.

Default value: false

<Catel DisableWarningsForAutoPropertyInitializers="true" />

See Auto-property initializers for an explanation of how this feature works.

GenerateXmlSchemas

Note: XML schema generation has been removed in Catel 7 along with the serialization engine. This option has no effect in projects targeting Catel 7 or later.

Generates XmlSchemaProvider attributes and the required static schema methods on all classes that inherit from ModelBase. Disabled by default because it is only needed for WCF-based serialization scenarios.

Default value: false

<Catel GenerateXmlSchemas="true" />
