C# feature request: implement interfaces on anonymous types

Question

I am wondering what it would take to make something like this work:

using System;

class Program
{
    static void Main()
    {
        var f = new IFoo { 
              


        

Answer 1

I have used in Java the Amonimous Class through the "new IFoo(){...}" sintax and it's practical and easy when you have to quick implement a simple interface.

As a sample it would be nice to implement IDisposable this way on a legacy object used just one time instead of deriving a new class to implement it.
