I try to use EF with MySQL in my project. And I add:
MySql.Data.EntityFrameworkCore
MySql.Data.EntityFrameworkCore.Design
into my project.json
but the tools section of project.json
is empty. When I run:
Scaffold-DbContext "myconnectionstr" MySql.Data.EntityFrameworkCore -OutputDir Models -StartupProject "myproject"
The console shows me an error:
Unable to find expected assembly attribute named DesignTimeProviderServicesAttribute in provider assembly MySql.Data.EntityFrameworkCore
It seems that "official" provider MySql.Data.EntityFrameworkCore 7.0.7-m61
still unsupports scaffolding. However, it works fine with Pomelo.EntityFrameworkCore.MySql
free community provider :
dotnet ef dbcontext scaffold "Host=localhost;Port=3306;Database=foodb;Username=root;Password=mysql" ^
Pomelo.EntityFrameworkCore.MySql ^
--force ^
--context "FooContext" ^
--output-dir "Entities" ^
--verbose
