我遵循了this link中提供的Entity Framework Core数据库第一种方法的官方Microsoft教程。
当我尝试执行以下命令从数据库生成模型时：
Scaffold-DbContext "Server=Data Source=DESKTOP-COJD62N;Initial Catalog=TrainGameDB;Integrated Security=True" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models -context TrainGameContext -Verbose
我得到以下输出：
Build started...
Build succeeded.
dotnet exec needs a managed .dll or .exe extension. The application specified was 'F:_IIT Level 6\UX\CW2 Backend\App2\TrainGameAPI\src\TrainGameAPI\bin\Debug\netcoreapp1.0\TrainGameAPI.runtimeconfig.json'
Process finished with non-zero exit code
