When i make an automatic Property what happen's in the background?

Question

edit : a completely different question than this i'm asking how auto-properties work internally

When i make an automatic Property what happen's in the background ?

This Equals to

public int SomeProperty {get; set;}

This

 private int _someField;
 public int SomeProperty 
 {
    get { return _someField;}
    set { _someField = value;}
 }

Is this what literally happens ( i.e a private field is created ) or is it only presented to just explain things and it works differently

Answer 1

Yes, it is exactly what happens, this:

public int SomeProperty {get; set;}

Is a syntactic sugar for this:

private int _someField;
public int SomeProperty 
{
   get { return _someField;}
   set { _someField = value;}
}

And it is a syntactic sugar for:

private int _someField;

public int get_SomeProperty()
{
    return _someField;
}

public void set_SomeProperty(int value)
{
    _someField = value;
} 

You can see the implementation yourself using ildasm.exe:

There are two methods generated to get and set the value of the private field. The only difference is that the name of generated field.
