ASP.NET 核心反向工程 model 与 MySql 现有数据库

Question

Im try to made a ASP.NET Core project with EF Codefirst and existing MySql database When I try to make the Reverse engineer ( following the article: Getting Started with EF Core on ASP.NET Core with an Existing Database )

I have a error. My MySql package is: MySql.Data.EntityFrameworkCore -Version 8.0.11

My Database is: TEST MY TABLE IS

CREATE TABLE USER (
  ID               BIGINT(20)  NOT NULL AUTO_INCREMENT,
  USERNAME         VARCHAR(50) NOT NULL,
  FIRSTNAME        VARCHAR(50) NOT NULL
) ENGINE=InnoDB; 

Im using the command:

Scaffold-DbContext "server=localhost;port=3306;user=root;password=123;database=TEST" MySql.Data.EntityFrameworkCore -OutputDir Models

The error:

System.NotImplementedException: The method or operation is not implemented.

   at Microsoft.EntityFrameworkCore.Scaffolding.Internal.ReverseEngineerScaffolder.ScaffoldModel(String connectionString, IEnumerable`1 tables, IEnumerable`1 schemas, String namespace, String language, String contextDir, String contextName, ModelReverseEngineerOptions modelOptions, ModelCodeGenerationOptions codeOptions)

   at Microsoft.EntityFrameworkCore.Design.OperationExecutor.OperationBase.Execute(Action action)
The method or operation is not implemented. 

Dos someone know how can I sold this? Is there any way to make the models if a Wizard like ASP.NET Web API in .NET Framework?

Answer 1

Try this its work for me. This is also NET Core-compatible MySQL connector + EF Core MySQL provider:

Pomelo.Data.MySql      
Pomelo.EntityFrameworkCore.MySql   
Pomelo.EntityFrameworkCore.MySql.Design

Answer 2

Scaffold-DbContext "server=localhost;user=root;password=1234;database=test1;" Pomelo.EntityFrameworkCore.MySql
