TLDR: here is the URL to download the English (en-US) MSI installer for SQL Server 2022 LocalDb:
For (my) future reference: here’s how I found it
- Download the SQL Server 2022 Express Installer
SQL2022-SSEI-Expr.exefrom the the SQL Server downloads page.
- Open it in ILSpy.
- Save the Microsoft.Sql.Installer.UI.Externals.InstallerEngine.dll embedded resource to a new file.
- Open this file in ILSpy also and locate the
Manifest_Media_Express_en-US.xmlembedded resource, in which you will find a reference to
SqlLocalDB.msi, which combined with the
DownloadRootURL just above it gives you the required location.
If you want the installer for other languages (e.g. German (de-DE), Spanish (es-ES)) then look in the
Manifest_Media_Express XML file for that language.
