Using SQL 2017 LocalDB as Shadow Database

We have a project using SQL Change Automation, building and deploying via VSTS. One of our projects needs to use some SQL 2017-specific functionality; we're targeting Azure SQL. We've set up a private agent with the SQL 2017 LocalDB tools installed and set the build to run on this agent. The "Set Target Database" step works fine and starts the localdb, but the "Build" step fails:

To create it, open a Command Prompt window and execute the following: SqlLocalDb create ReadyRollShadow

Is there a specific parameter we need to set or something we need to update to get LocalDB 2017 to work?

    Hello Eric,

    I do confirm that LocalDB 2017 is supported by SQL Change Automation projects and doesn't require any additional configuration.
    However, there is a known issue regarding LocalDB itself. It should be enough just to delete the instance by running: 
    SqlLocalDB.exe delete ReadyRollShadow
    For a more detailed guidance, see https://www.red-gate.com/sca/localdb-instance-troubleshooting .

    Please also note, that in case you encounter an error similar to:
    CREATE FILE encountered operating system error 5(Access is denied.) while attempting to open or create the physical file 'C:\Users\usernameDatabaseName.mdf'
    you just need to update the LocalDB with the Cumulative Update >= 6. For more details see https://dba.stackexchange.com/a/191748/161450 .

    I also recommend updating the legacy ReadyRoll VSTS pipeline to a recent one that uses SQL Change Automation PowerShell.

    Also, I'm pretty sure that you've done this already, but for the future reference, it's recommended to target a proper database version in a sqlproj file. You can do this either using the project properties page or by directly editing the sqlproj file and setting the below value (in this case for SQL Server 2017):
    <DSP>Microsoft.Data.Tools.Schema.Sql.Sql140DatabaseSchemaProvider</DSP>

    Hi All,

    The error ended up being "LocalDB parent instance version is invalid: MSSQL11E.LOCALDB" which was resolved by deleting the GUID entry located at HKEY_CURRENT_USER\SOFTWARE\Microsoft\Microsoft SQL Server\UserInstances (this may have just needed the data for the ParentInstance value modified to MSSQL14E.LOCALDB).

    Kind regards,
    Alex
