This means that the database columns, tables and data will be defined by code and will thus be created from scratch when the application runs. This one starts with an already existing database and generates code from it. Please note that this post is about Entity Framework Core and not Entity Frameowrk 6. Prerequisites: Visual Studio Code c extensions: and.net Core DB Browser for SQLite to check then content of the database, Initializing the project: P l ease follow these simple steps to get started Start visual studio code (easy ) Create an empty folder on your hard drive. Open that folder in visual studio code Next, open a terminal ( on mac). The working directory should be our project directory since it is the current folder on visual studio code. Otherwise, just cd to that folder using the terminal commands. Run the following commands to start a new.Net Core project at the current location dotnet new console; this will create a project file and a code file. You can use the vscode-nuget-package-manager extension to help you install it. Can You Get Visual Studio Update The ProjectRun again dotnew restore to update the project with the new package. Lets write some code Lets code some: Okay, we are doing great. We are ready to start writing a code first Entity Framework Core application. Lets develop an application that allows me to store in a SQLite database my video game collection (so that I wont buy the same game twice ). In order to achieve that, we will perform the following tasks: Create a C class that represents a video game Crete a class that inherits from DbContext which represent a database session. Can You Get Visual Studio Free To AddWrite CRUD code Starting with the VideoGame class, we are going to define it like this: Right click on the folder view to quickly create a Class You are free to add colums and annotations: Next, we will define a DbContext sublass. Its roles are to specify the path of the sqlite file and that we are mapping the VideoGame class to a table. Here is the code allowing to achieve this: Finally, we will add some CRUD code. ![]() Please read the comments for more information: You should see the following text on the output view: You can check that sqlite file is created in the binnetcoreapp folder (which is the default working directory). DB Browser for SQLite allows to check the content of the database We have successfully created a console app without writing a single SQL command. Of course, we can write SQL commands if we want or if you like them.
