DacFx .NET Core generate .dacpac without Origin.xml

[lucas-mv]

I managed to generate a .dacpac file programmatically from a model on Ubuntu 18.04 with .NET core 2.2 but the file came without the Origin.xml file, am I doing something wrong?

using System;
using System.IO;
using Microsoft.SqlServer.Dac.Model;
using Microsoft.SqlServer.Dac;

namespace dacpacPOC
{
    class Program
    {
        static void Main(string[] args)
        {
            var script = "CREATE SCHEMA [Test]\r\nGO\r\n" +
                "CREATE TABLE [Test].[Identity]([TestId] int NOT NULL IDENTITY,\r\n" +
                "CONSTRAINT [PK_Identity] PRIMARY KEY ([TestId]))\r\nGO\r\n";
            var tSqlModelOptions = new TSqlModelOptions
            {
                AnsiNullsOn = true,
                Collation = "Latin1_General_CI_AI",
                CompatibilityLevel = 130,
                QuotedIdentifierOn = true
            };
            var outputFilename = "Identity.dacpac";
            using (var tSqlModel = new TSqlModel(SqlServerVersion.Sql130, tSqlModelOptions))
            {
                tSqlModel.AddObjects(script);
                if (File.Exists(outputFilename))
                {
                    File.Delete(outputFilename);
                }
                DacPackageExtensions.BuildPackage(outputFilename, tSqlModel, new PackageMetadata { Name = outputFilename }, new PackageOptions { });
            }
        }
    }
}

My .csproj file is the following:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp2.2</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.SqlServer.DACFx" Version="150.4384.2-preview" />
  </ItemGroup>

</Project>

There was a bug on .NET Core where writing to a .bacpac file would throw an exception, so the origin.xml file would not be written. This is fixed in the latest nuget packages. I think the above code missed the exception since it's not using a try{} catch{} block to log failures in the catch.
