Update "propdp" snippet to use nameof

[vsfeedback]

This issue has been moved from a ticket on Developer Community.

---

The propdp C# code snippet creates the following code:

public int MyProperty
{
    get { return (int)GetValue(MyPropertyProperty); }
    set { SetValue(MyPropertyProperty, value); }
}

// Using a DependencyProperty as the backing store for MyProperty.  This enables animation, styling, binding, etc...
public static readonly DependencyProperty MyPropertyProperty =
    DependencyProperty.Register("MyProperty", typeof(int), typeof(ownerclass), new PropertyMetadata(0));

Notice the "MyProperty" string literal, which points to the backing property for the dependency property. This is not ideal, because renaming the property will not change this string and will cause unexpected problems at runtime. Instead, the code snippet could generate the following:

...
public static readonly DependencyProperty MyPropertyProperty =
    DependencyProperty.Register(nameof(MyProperty), typeof(int), typeof(ownerclass), new PropertyMetadata(0));

Using the nameof operator, the code would gain compile time safety and would automatically update the reference whenever the property name changes.

I'm curious why this got filed under the roslyn project? Isn't' that the compiler engine? This just seems like a Visual Studio feature.

Roslyn supplies the VS IDE side of thing for C#/VB and portions of F#/TS/JS/Xaml.

FWIW there is a StackOverflow post which gets some notice about this same issue. It proposes a local workaround for developers to modify the snippet file.

Is this a dupe of #5574 ?

(@sharwell I suggest closing this as a dupe of that one?)
