Problem
How to use Entity Framework Core migrations in ASP.NET Core project.
Solution
This is a continuation of the previous post on creating CRUD with ASP.NET Core and EF Core.
To utilize the EF migrations, add NuGet package to ASP.NET Core Web Application project: Microsoft.EntityFrameworkCore.Design
Add CLI tools by editing .csproj file.
- <ItemGroup>
- <DotNetCliToolReference
- Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="2.0.0" />
- </ItemGroup>
Here is a list of .NET CLI commands relating to EF migrations.
NOTE
You’ll need to run CLI commands from within ASP.NET Core Web Application project, however, point to the project containingDbContext and Entities using -p option (for add and remove commands).
