尝试在与 Pomelo.EntityFrameworkCore.MySql 相关的 dotnet core 3.1 中添加迁移时出错

我收到此错误时,

dotnet ef migrations add InitialMigration
Run Code Online (Sandbox Code Playgroud)

来自程序集“Pomelo.EntityFrameworkCore.MySql,版本=3.2.3.0,Culture=neutral,PublicKeyToken=2cc498582444921b”的“Pomelo.EntityFrameworkCore.MySql.Query.ExpressionVisitors.Internal.MySqlSqlTranslatingExpressionVisitorFactory”类型中的方法“Create”没有实现。

Entity Framework Core .NET 命令行工具 5.0.0-rc.2.20475.6

完全错误 -
