Dto suffix casing (ARCH005)

Key dotnet.naming.dto-suffix-casing · Severity warning · Category naming

The DTO suffix should be written as PascalCase Dto in type and variable names; variants like DTO or dto should be avoided.

Incorrect

public class OrderDTO
{
    public int Id { get; set; }
}

Correct

public class OrderDto
{
    public int Id { get; set; }
}

Fix

Rename so the suffix is PascalCase Dto. If needed, suppress the rule per project/workspace via except/ignore.
