There are drawbacks to scaffolding that we can avoid by starting with a Code-First approach. NET applications that are designed to perform a niche task. Targeting tables are useful when building microservices or. We can also selectively scaffold parts of an existing database by specifying table names. We must specify the appropriate database provider when scaffolding so that the scaffolding can respect the SQL syntax of our database. dotnet ef dbcontext scaffold "Data Source=(localdb)\MSSQLLocalDB Initial Catalog=Chinook" We can ask the CLI to scaffold entities and relationships from an existing database using the scaffold command. Developers should first look at the scaffolding features built into the EF Core CLI tools. When working with a legacy database or complicated organizational power dynamics, we may be tempted to handcraft each entity and define every relationship within the DbContext.OnModelCreating method. If it’s impossible to do so due to organizational reasons, consider the next section as a possible solution. Database administrators and developers should work towards delivering value for users. Developers should embrace EF Core defaults as much as possible to avoid strange edge cases and exceptions.ĭepending on your organization and responsibility delegation, it may be best to have a conversation about EF Core naming conventions and adopt them as an understood methodology to design and evolve schema. Still, modifications to the naming conventions within EF Core come with significant maintenance costs and the potential to introduce mapping bugs. EF Core allows developers to work with organizational units to adapt to different naming styles.
Adopting non-conventional namingĮF Core 5 runtime packages contain conventions around schema naming, which are typically considered best practices. Installing the tools to the solution helps us avoid drift and conflicts when working on multiple solutions with varying versions. The latest versions are 5.0.1 for both the CLI and EF Core packages, as of the publication of article. The EF Core documentation recommends that developers use the tools package that matches the runtime packages’ major version.

From here, we can install the EF Core CLI tools. We can then install the CLI tools to our solution locally.
config directory with a dotnet-tools.json file. From the solution folder, we can run the following dotnet command. To install the tool locally for each solution, we first need to create a tool manifest. While we can install the tooling globally, it’s best to version the CLI tooling and EF Core together in your solution.
DBCONTEXT SQLITE SCHEMA SUPPORT UPGRADE
The upgrade from previous versions might tempt us to install the EF Core CLI tooling globally on our development environments.
Though this post is packed with important information, it is by no means conclusive.ĮF Core has gone through several iterations to deliver a repeatable command-line interface. I’ve compiled and consolidated this information to help you get a general overview of potential mistakes you may encounter. Knowing that EF Core is different, I took some time to explore the EF Core documentation and determine the existing pitfalls you might encounter when starting your EF Core journey.

While some conceptual pitfalls have made it from previous versions of EF, the EF Core team’s care in addressing previous problems was evident to me as I read through the EF Core documentation and worked on this post’s code samples. Getting started with EF Core is relatively straightforward, but mastering it can take an entire career.Īs a long-time user of earlier Entity Framework versions, I started writing this post with many preconceived notions about pitfalls from that experience. In this post, we’ll look at some pitfalls and ideas EF Core users like yourself may want to consider when developing an application.Įntity Framework Core (EF Core) is a ground-up rewrite of Microsoft’s object-database mapping framework.
