Asp.net core MVC 6.Program.cs中如何禁用scope验证

Question

when I try to run the line:

ApplicationDbContext context = app.ApplicationServices.GetRequiredService<ApplicationDbContext>()

I get presented with an error: "System.InvalidOperationException: 'Cannot resolve scoped service 'SportsStore.Models.ApplicationDbContext' from root provider.'"

I saw an answer to a similar question( Cannot resolve scoped service from root provider - solution to error? ), but idk how to do it in asp.net core mvc 6.0.

Have you tried:

using (var scope = app.ApplicationServices.CreateScope())
{
    var context = scope.ServiceProvider.GetRequiredService<ApplicationDbContext>();
    // Do something...
}
