After installing latest patch 3 version, upon launch login connection to Azure SQL database with Entra ID throws this error:
This is a Microsoft.Data.SqlClient + MSAL/WAM issue.
Your data layer is opening a SQL connection whose connection string uses Authentication=Active Directory Interactive. On that first DB call (get_GlobalSettingsBaseItem), Microsoft.Data.SqlClient hands the interactive auth off to MSAL. In recent versions (Microsoft.Data.SqlClient 5.0+, and .NET on Windows) MSAL routes interactive login through the WAM broker, which needs a parent window handle (HWND) so it can anchor the account picker. Your code never supplies one, so MSAL throws window_handle_required.
This almost certainly appeared after a NuGet upgrade of Microsoft.Data.SqlClient (or a runtime bump) — older versions fell back to an embedded/system browser and didn't require the handle.
Code:
