Should I Install LocalDB Separately if I Already Have SQL Server Express and .NET?

LocalDB Installation: Separate Installation or Integrated with SQL Server Express?

Question:

Is a separate installation required for LocalDB if SQL Server 2008 R2 Management Studio, SQL Server 2012, and .NET 4.0.2 are already installed?

Answer:

Yes, installing LocalDB separately may be necessary if it is not selected during the installation of SQL Server Express.

Primary Installation Method:

• Integrated with SQL Server Express: LocalDB is typically installed with SQL Server Express by selecting it on the Feature Selection page during installation.

Standalone Installation:

If you wish to install LocalDB separately, you can download the standalone SqlLocalDB.msi file from the SQL Express download page.

Locating LocalDB Instance:

To ensure LocalDB is installed on your system, you can try connecting to (localdb)Projects using Management Studio.

Additional Notes:

• There can be only one installation of LocalDB binary files for each major SQL Server Database Engine version.
• Multiple Database Engine processes use the same binaries.
• LocalDB instances have the same limitations as SQL Server Express.
