![]() We’ll use this class library project to implement EF Core migrations. Install the EF Core NuGet packagesĬreate a class library project in the same ASP.NET Core 7 Web API project we created above. You can work with migrations either from within Visual Studio via the Package Manager Console or by using a command-line tool to run the EF Core CLI commands. Note that migrations are enabled in EF Core by default. ![]() Using migrations, developers can precisely log changes to the database schema, implement those changes in a well-organized manner, and undo any changes or modifications if required. You can take advantage of migrations to enhance or alter your database schema by adding, eliminating, or altering database elements like tables, indexes, columns, and associations. Migrations help you ensure that the database schema and the domain model in your application are in sync. Without migrations, applying these changes to a database would be difficult and error-prone.Ī migration is the process of managing changes to a database schema as they occur over time. These changes could involve adding new tables, modifying existing tables, or deleting tables altogether. In software development, it's common to make changes to the data model as requirements evolve. We’ll use this ASP.NET Core 7 Web API project to work with EF Core migrations in the sections below. Ensure that the check boxes “Enable Open API Support,” “Configure for HTTPS,” and “Enable Docker” are unchecked as we won’t be using these features here.Leave the “Authentication Type” set to “None” (default). In the “Additional Information” window shown next, uncheck the check box that says “Use controllers…” since we’ll be using minimal APIs in this example.Optionally check the “Place solution and project in the same directory” check box, depending on your preferences.In the “Configure your new project” window, specify the name and location for the new project. ![]() In the “Create new project” window, select “ASP.NET Core Web API” from the list of templates displayed.Or Update-Database: > dotnet ef database updateįor ASP.NET Zero Power Tools on Mac, there is no Visual Studio extension, so you need to create the JSON input file it manually, then run: > dotnet AspNetZeroRadTool.dll YourEntity. Then navigate in browser to There is no Package Manager Console in Visual Studio for Mac, so in Terminal you can Add-Migration: > dotnet ef migrations add InitialCreate Then go to base_folder/angular and: > npm start Run the project in Visual Studio for Mac, it should take you to Go to " base_folder/angular/src/assets/" and change port in remoteServiceBaseUrl from " 22742" to " 5000" in appconfig.json file before running the angular application. Open the terminal in the EntityFrameworkCore project folder(eg, The ef cli commands in this article are all executed under this folder): > dotnet add package Ĭheck your dotnet ef install: > dotnet efĪfter that, run the command below to create your database: > dotnet ef database update Go here: and see Installing the Tools section. Set Web.Host project as Startup Project (right click on Web.Host project in Solution Explorer and you will see the option) If you are not going to work on Xamarin app, open the Web solution only, under base_folder/aspnet-core. Open the application in Visual Studio for Mac. Otherwise when you start-up you will see a Connection Refused error in the browser console. ) and in Azure Portal click on your database, then the " Set server firewall" button, then create a rule for your IP address (or range of addresses) and Save. Note: You have to get your IPv4 address (e.g. You can set your SQL Server database up in Azure Portal, and there got connection string like this, into appsettings.json: "ConnectionStrings": , SQL Server database on Azure is used in this example. If you want to use a different database provider, please check. The application is configured to work with SQL Server by default. In the terminal, go to base_folder/angular and run the yarn command: yarn ![]() Do not check the "One solution" option when creating your project.
