DefaultMetadataResolver

Methods

GetProvider(Type)

Gets the metadata provider for a type. Returns generated metadata if available, otherwise uses reflection.

[RequiresUnreferencedCode("Falls back to reflection when no generated metadata is available. Use the source generator for AOT compatibility.")]
public ICommandMetadataProvider GetProvider(Type modelType)

Parameters

modelType Type

The model type.

Returns

ICommandMetadataProvider

A metadata provider for the type.

Remarks

This method first checks for source-generated metadata (AOT-friendly). If no generated metadata exists, it falls back to reflection-based metadata extraction. For full AOT compatibility, ensure the CommandLineUtils.Generators package is referenced and the source generator runs during compilation.

GetProvider<TModel>()

Gets the metadata provider for a type. Returns generated metadata if available, otherwise uses reflection.

[RequiresUnreferencedCode("Falls back to reflection when no generated metadata is available. Use the source generator for AOT compatibility.")]
public ICommandMetadataProvider<TModel> GetProvider<TModel>() where TModel : class

Returns

ICommandMetadataProvider<TModel>

A metadata provider for the type.

Type Parameters

TModel

The model type.

Remarks

This method first checks for source-generated metadata (AOT-friendly). If no generated metadata exists, it falls back to reflection-based metadata extraction. For full AOT compatibility, ensure the CommandLineUtils.Generators package is referenced and the source generator runs during compilation.

HasGeneratedMetadata(Type)

Checks if generated metadata is available for a type.

public bool HasGeneratedMetadata(Type modelType)

Parameters

modelType Type

The model type.

Returns

bool

True if generated metadata is available; otherwise, false.
