VB -> C#: Assignment operators of parameterized properties are not resolved

[gaschd]

Shorthand assignment operators like "+=" or "-=" are not resolved for parameterized properties.

VB.Net input code

Public Class TestClass
    Private _items As Integer() = New Integer() {1}
    Public Property Item(index As Integer) As Integer
        Get
            Return _items(index)
        End Get
        Set(value As Integer)
            _items(index) = value
        End Set
    End Property

    Private _strItems As String() = New String() {""Hello""}
    Public Property StrItem(index As Integer) As String
        Get
            Return _strItems(index)
        End Get
        Set(value As String)
            _strItems(index) = value
        End Set
    End Property

    Public Sub AllAssignmentOperators()
        Item(0) += 2        
        Item(0) *= 2         
        Item(0) ^= 2     
        Item(0) /= 2        
        Item(0) -= 2        
        Item(0) \= 2        
        Item(0) <<= 2
        Item(0) >>= 2
        StrItem(0) &= "" World""
    End Sub
End Class

Erroneous output

using System;

public partial class TestClass
{
    private int[] _items = new int[] { 1 };
    public int get_Item(int index)
    {
        return _items[index];
    }
    public void set_Item(int index, int value)
    {
        _items[index] = value;
    }

    private string[] _strItems = new string[] { ""Hello"" };
    public string get_StrItem(int index)
    {
        return _strItems[index];
    }
    public void set_StrItem(int index, string value)
    {
        _strItems[index] = value;
    }

    public void AllAssignmentOperators()
    {
        get_Item(0);
        get_Item(0);
        get_Item(0);
        get_Item(0);
        get_Item(0);
        get_Item(0);
        get_Item(0);
        get_Item(0);
        get_StrItem(0);
    }
}

Expected output

using System;

public partial class TestClass
{
    private int[] _items = new int[] { 1 };
    public int get_Item(int index)
    {
        return _items[index];
    }
    public void set_Item(int index, int value)
    {
        _items[index] = value;
    }

    private string[] _strItems = new string[] { ""Hello"" };
    public string get_StrItem(int index)
    {
        return _strItems[index];
    }
    public void set_StrItem(int index, string value)
    {
        _strItems[index] = value;
    }

    public void AllAssignmentOperators()
    {
        set_Item(0, get_Item(0) + 2);
        set_Item(0, get_Item(0) * 2);
        set_Item(0, (int)Math.Round(Math.Pow(get_Item(0), 2d)));
        set_Item(0, (int)Math.Round(get_Item(0) / 2d));
        set_Item(0, get_Item(0) - 2);
        set_Item(0, get_Item(0) / 2);
        set_Item(0, get_Item(0) << 2);
        set_Item(0, get_Item(0) >> 2);
        set_StrItem(0, get_StrItem(0) + "" World"");
    }
}
