NDLRGEN061: Record constructor overload conflicts with field-based generation

Cause

The same type combines [RecordConstructorOverloadParameter] with [GenerateConstructor] or a positive field-level generated-constructor trigger.

Rule Description

The two features have different ownership:

  • field-based generation owns an ordinary class constructor and Needlr DI metadata;
  • record-overload generation adds one forwarding constructor to a positional record and remains outside DI metadata.

Needlr does not compose those constructor models implicitly.

How to Fix

// WRONG
[GenerateConstructor]
public partial record Request(string Name)
{
    [RecordConstructorOverloadParameter]
    public int Revision { get; init; }
}

// CORRECT
public partial record Request(string Name)
{
    [RecordConstructorOverloadParameter]
    public int Revision { get; init; }
}

For an ordinary class, remove the record marker and use eligible private readonly fields with [GenerateConstructor].
