DbUp Migration is a free tool for .NET that simplifies the process of deploying and upgrading databases for SQL Server, MySQL, PostgreSQL, Oracle, and SQLite. It automates the management of database schema and data changes by applying scripts to your target database. Code First Migration and DbUp Migration are both tools used for managing database schema and data changes in .NET applications, but they have different approaches and features. Code First Migration is a feature of Entity Framework, an ORM tool for .NET. It enables you to define database changes using C# code, which can then be used to generate SQL scripts. This approach is helpful for developers who prefer working with C# code and want to use Entity Framework's features, such as data modeling and querying. Learn Beginners: Code First Database Migration in Entity Framework from the previous article. DbUp Migration is a standalone migration tool that allows you to define database changes using SQL scripts. It's a more flexible tool that supports multiple database platforms and allows you to write plain SQL scripts to define database changes. Additionally, DbUp Migration offers advanced features such as transactional migrations, conditional scripts, and pre-processing scripts. The source code for this article can be found on GitHub. This article is based on .Net Core 6 Program.cs SchoolDbContext.cs All Make sure to enable DbUp Migration also offers the ability to run migrations from a command line or from within a CI/CD pipeline, which can streamline the deployment process. DbUp Migration is an excellent tool for managing database schema and data changes in .NET applications. It offers many benefits, including: The source code for this article can be found on GitHub. In summary, DbUp Migration is a free and open-source tool for .NET that simplifies the process of deploying and upgrading databases. It allows you to define database changes using plain SQL scripts and supports multiple database platforms. DbUp Migration offers advanced features such as transactional migrations, conditional scripts, post-deployment scripts, and pre-processing scripts. It is highly extensible and customizable and can be run from the command line or within a CI/CD pipeline. Overall, DbUp Migration can streamline the database deployment process and make it easier to manage schema and data changes.What is Dbup Migration?

. See the following snapshot.
one-time scripts
should include checking for existing data and resources and making sure data or resource is not duplicated on the SQL Server side. These scripts are run exactly once per database, and never again. Think of things like creating table... statements. You can't create a table twice so any attempt to run the script second-time results in an error. Embedded resource

from file properties, see the snapshot below.Output Window - Notice all scripts ran successfully with no issues.
SQL Server View - Tables are created through automatic migration
SchemaVersions
is a table that DBUp uses to keep track of the version of the database schema as it changes over time through migrations. It helps to ensure that the database schema is up-to-date and provides a history of the changes made to the schema.
