Property class Length Annotation PersistedResolvableAnnotation

I found the issue myself. I will document it in case anyone else is facing the issue in future.

The following user definition:

CREATE USER [Angela] WITHOUT LOGIN
    WITH DEFAULT_SCHEMA = [Angela];

created the following code in the model.xml that avoids publishing, maybe because the schema (Angela) used there is invalid because it simply does not exist:

<Element Type="SqlUser" Name="[Angela]">
            <Property Name="IsWithoutLogin" Value="True" />
            <Relationship Name="DefaultSchema">
                <Entry>
                    <Annotation Type="PersistedResolvableAnnotation" Name="[Angela]">
                        <Property Name="TargetTypeStorage" Value="SqlSchema" />
                        <Property Name="Length" Value="9" />
                        <Property Name="Offset" Value="63" />
                    </Annotation>
                </Entry>
            </Relationship>
        </Element>

After changing the user definition to:

CREATE USER [Angela] WITHOUT LOGIN
    WITH DEFAULT_SCHEMA = [dbo];

the model lookes as followes and could be published:

<Element Type="SqlUser" Name="[Angela]">
        <Property Name="IsWithoutLogin" Value="True" />
    </Element>

I have a feeling that this strange behavior is kind of a follow-up of another misbehavior because I would expect the not existing schema to raise a compiler error.

For me, the solution was that I was using an outdated version of SqlPackage.exe.

Old version path:

C:\Program Files (x86)\Microsoft SQL Server\110\DAC\bin\SqlPackage.exe

New version path:

C:\Program Files (x86)\Microsoft SQL Server\130\DAC\bin\SqlPackage.exe

It is installed by Microsoft SQL Server Data Tools (SSDT).
