I'm using LightSpeed, which generates the following classes:

    [System.CodeDom.Compiler.GeneratedCode("LightSpeedModelGenerator",
"1.0.0.0")]
    public static partial class BookCatalogDtoExtensions
    {
      static partial void CopyBookCatalogDtoBase(Entity entity,
BookCatalogDtoBase dto);
      static partial void CopyBookCatalogDtoBase(BookCatalogDtoBase dto, Entity
entity);

      static partial void BeforeCopyAuthor(Author entity, AuthorDto dto);
      static partial void AfterCopyAuthor(Author entity, AuthorDto dto);
      static partial void BeforeCopyAuthor(AuthorDto dto, Author entity);
      static partial void AfterCopyAuthor(AuthorDto dto, Author entity);

      private static void CopyAuthor(Author entity, AuthorDto dto)
      {
        BeforeCopyAuthor(entity, dto);
        CopyBookCatalogDtoBase(entity, dto);
        dto.Name = entity.Name;
        dto.Code = entity.Code;
        AfterCopyAuthor(entity, dto);
      }

      private static void CopyAuthor(AuthorDto dto, Author entity)
      {
        BeforeCopyAuthor(dto, entity);
        CopyBookCatalogDtoBase(dto, entity);
        entity.Name = dto.Name;
        entity.Code = dto.Code;
        AfterCopyAuthor(dto, entity);
      }
      ....
    }

As you can see, the CopyAuthor method calls the empty partial methods
BeofreCopyAuthor and AfterCopyAuthor.
These methods are defined by LightSpeed as:
      static partial void BeforeCopyAuthor(Author entity, AuthorDto dto);
      static partial void AfterCopyAuthor(Author entity, AuthorDto dto);
      static partial void BeforeCopyAuthor(AuthorDto dto, Author entity);
      static partial void AfterCopyAuthor(AuthorDto dto, Author entity);

And are not defined anywhere else in the code.
According to the "specification" for partial methods, these calls should be
removed by the compiler entirely.


Reproducible: Always

Steps to Reproduce:
Try to call an empty partial method
Actual Results:  
Compiler error

Expected Results:  
Should compile cleanly
