❔ xunit field scope

lets say i have a class for unit testing below:

class Tests
{
  Dependency dep1;
  
  public Tests()
  {
    dep1 = new Dependency();
  }

  [Fact]
  public void test1()
  {
    Service s1 = new Service(dep1);
    ...
  }

  [Fact]
  public void test2()
  {
    Service s2 = new Service(dep1);
    ...
  }
}

class Tests
{
  Dependency dep1;
  
  public Tests()
  {
    dep1 = new Dependency();
  }

  [Fact]
  public void test1()
  {
    Service s1 = new Service(dep1);
    ...
  }

  [Fact]
  public void test2()
  {
    Service s2 = new Service(dep1);
    ...
  }
}

will s1 and s2 have the same dep1 instance or will they get different ones? thanks

Also you could verify this just by logging GetHashCode method
