Is your feature request related to a problem?

We should be able to combine these:

[NodeResolver]
public static Task<Draft?> Get(
    OrganisationWorkflowDraftId id,
    QueryContext<Draft> queryContext,
    IDraftByIdDataLoader draftByIdDataLoader,
    CancellationToken cancellationToken) =>
    GetDraft(id, queryContext, draftByIdDataLoader, cancellationToken);

[Query]
public static Task<Draft?> GetDraft(
    [ID(TypeName)] OrganisationWorkflowDraftId id,
    QueryContext<Draft> queryContext,
    IDraftByIdDataLoader draftByIdDataLoader,
    CancellationToken cancellationToken) =>
    draftByIdDataLoader
        .With(queryContext)
        .LoadAsync(id.WorkflowId, cancellationToken);

The solution you'd like

[NodeResolver]
[Query]
public static Task<Draft?> GetDraft(
    OrganisationWorkflowDraftId id,
    QueryContext<Draft> queryContext,
    IDraftByIdDataLoader draftByIdDataLoader,
    CancellationToken cancellationToken) =>
    GetDraft(id, queryContext, draftByIdDataLoader, cancellationToken);

You can.

@michaelstaib we tried. When they are separate (as shown in the example above) it works, but when trying:

[NodeResolver]
[Query]
public static Task<Entity?> GetDraft(
    OrganisationWorkflowDraftId id,
    IResolverContext resolver,
    WorkflowByIdDataLoader workflowById,
    CancellationToken cancellationToken) =>
    Shared.Find(id.WorkflowDraftId, selection: resolver.Select(), workflowById, cancellationToken);

we get

InputObject `OrganisationWorkflowDraftIdInput` has no fields declared. (HotChocolate.Types.InputObjectType<X.Domain.Core.Workflows.Drafts.OrganisationWorkflowDraftId>)

OR

[NodeResolver]
[Query]
public static Task<Entity?> GetDraft(
    [ID(TypeName)] OrganisationWorkflowDraftId id,
    IResolverContext resolver,
    WorkflowByIdDataLoader workflowById,
    CancellationToken cancellationToken) =>
    Shared.Find(id.WorkflowDraftId, selection: resolver.Select(), workflowById, cancellationToken);

we get

The object type `OrganisationWorkflowDraftId` has to at least define one field in order to be valid. (HotChocolate.Types.ObjectType<X.Domain.Core.Workflows.Drafts.OrganisationWorkflowDraftId>)

PS: Also, from my investigation it seems that the source generator does not work for [NodeResolver] when combined with [Query].
