This repository has code samples for working with SQL-Server LocalDb databases using C# 9 (or higher), .NET Core 5 (or higher). Each code sample will have a readme file explaining purpose and details on how to use plus any caveats.
Expected developer experience level, has a decent understanding for working with SQL and Entity Framework Core.
Microsoft SQL Server Express LocalDB is a feature of SQL Server Express targeted to developers.
LocalDB is a special, low impact version of the SQL Server engine, that is not installed as a Windows Service, but launched (made to run) on demand by the ADO.NET client opening a connection to it. It is intended for single user scenarios, and not for any production use - for production you should use SQL Server Express (or higher)
- 12/05/2021 Only one code sample, how to create a localDb in code.
- 12/14/2021 Added code in LocalDbLibraryConsoleApp to create a LocalDb version of NorthWind database
- 12/14/2021 Added Entity Framework Core 5 class project which relies on LocalDbLibraryConsoleApp to first create the database.
| Project | Description |
|---|---|
| LocalDbLibrary | Code to create a localDb in code |
| NorthWindLibrary | Uses NorthWind database created in project LocalDbLibraryConsoleApp |
| LocalDbLibraryConsoleApp | Test project for LocalDbLibrary |
Creating the database in the console app then attempting to in the windows form app or reverse will cause a runtime exception as the database can not be duplicated. So after running one of the projects and want to run the other detach/delete the first database which is easy in SSMS.
- SQL Server Express LocalDB installed
- Visual Studio 2019 or higher
- In some cases proper permissions to SQL-Server
Have SSMS (SQL-Server Management Studio) installed
Command-Line Management Tool: SqlLocalDB.exe
SqlLocalDB.exe is a simple tool that enables the user to easily manage LocalDB instances from the command line. It is implemented as a simple wrapper around the LocalDB instance API. As in many similar SQL Server tools (for example, SQLCMD), parameters are passed to SqlLocalDB as command-line arguments and output is sent to the console.
Use the SqlLocalDB utility to create an instance of MicrosoftSQL Server 2016 Express LocalDB. The SqlLocalDB utility (SqlLocalDB.exe) is a simple command line tool to enable users and developers to create and manage an instance of SQL Server Express LocalDB. For information about how to use LocalDB.
