SqlClient error when getting IsSqlDw property from a Fabric DW

Repro:

using Microsoft.Data.SqlClient;
using Microsoft.SqlServer.Management.Common;
using Microsoft.SqlServer.Management.Smo;

var sqlConnection = new SqlConnection("<Fabric_DW_connection_string>");
sqlConnection.Open();

ServerConnection serverConnection = new ServerConnection(sqlConnection);
Server server = new Server(serverConnection);
Database db = new Database(server, "testDwName");
db.Refresh();

Console.WriteLine(db.IsSqlDw);

The last line fails with this error:

Unhandled exception. Microsoft.SqlServer.Management.Common.ExecutionFailureException: An exception occurred while executing a Transact-SQL statement or batch.
 ---> Microsoft.Data.SqlClient.SqlException (0x80131904): Warning: Fatal error 615 occurred at May 31 2024  7:23PM. Note the error and time, and contact your system administrator.

Comienza en Database.IsSqlDw y sigue la ruta de inicialización y consulta mostrada en el stack trace, especialmente DatabaseLevel.GetData y la inicialización de SqlSmoObject. Reproduce el acceso a la propiedad contra un Fabric DW e identifica por qué la consulta generada provoca el error SQL informado; el trabajo estará terminado cuando db.IsSqlDw pueda leerse sin lanzar una excepción.
