尝试使用代码生成器在aspnet core 3中生成控制器时出错

Question

我正在使用MYSQL数据库在asp net core 3.1.1]中启动一个新项目。我可以使用以下命令来搭建模型]

dotnet ef dbcontext scaffold "Server=localhost;User=root;Password=123456;Database=proyecto;TreatTinyAsBoolean=true;" Pomelo.EntityFrameworkCore.MySql -o Models

但是当我尝试使用aspnet-codegenerator生成任何控制器时，它会产生以下错误：不支持选项'数据服务器'。

这是模型

        public virtual TipoIdentificacion TipoIdentificacion { get; set; }
        public virtual ICollection<EntidadFiscalContacto> EntidadFiscalContacto { get; set; }
    }
}
这是startup.cs
文件中的我的服务配置

public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllersWithViews();

             // other service configurations go here
            // replace "YourDbContext" with the class name of your DbContext
            services.AddDbContextPool<LCoreContext>(options => options
                // replace with your connection string
                .UseMySql(Configuration.GetConnectionString("LCoreConnection"), mySqlOptions => mySqlOptions
                    // replace with your Server Version and Type
                    .ServerVersion(new Version(10, 3, 14), ServerType.MySql)
            ));
        }
数据库连接错误不能是因为我可以生成模型。另一方面，我尝试创建一个没有关联模型的控制器，并且没有问题。这是我使用的命令。
dotnet aspnet-codegenerator  controller -name ContactosController  -dc LCoreContext -outDir Controllers -actions
任何帮助或暗示您可以提供给我，我将不胜感激。

我正在使用MYSQL数据库在ASP Net Core 3.1.1中启动一个新项目。我可以使用以下命令来搭建模型：dotnet ef dbcontext scaffold“ Server = localhost; User = root; ...

错误消息Option 'data server' not supported.告诉您，您正在data server连接字符串中使用名为LCoreConnection的选项。

Pomelo不支持此选项（有关支持的选项，请参见MySQL .NET Connection String Options。
