在以下情况中,由于方法调用而嵌套了两个DbContexts:

public void Method_A() {
    using (var db = new SomeDbContext()) {
        //...do some work here
        Method_B();
        //...do some more work here
    }
}

public void Method_B() {
    using (var db = new SomeDbContext()) {
        //...do some work
    }
}

题:

1. 这种嵌套会导致任何问题吗？(并且正确的DbContext会在正确的时间处理吗？)

2. 如果将Method_A重构为:这种嵌套被认为是不好的做法:

   public void Method_A() {
       using (var db = new SomeDbContext()) {
           //...do some work here
       }
   
       Method_B();
   
       using (var db = new SomeDbContext()) {
           //...do some more work here
       }
   }
