Summary: Cannot implement interface when interface already
implemented on base class
Description:
The following code produces error: no interface implemented by `Something2'
contains method named `DoSomething' (looking for `ISomething.DoSomething')
using System;
public interface ISomething
{
DoSomething() : void;
}
public class Something: ISomething
{
ISomething_DoSomething() : void implements ISomething.DoSomething
{
Console.WriteLine("Something.DoSomething");
}
}
public class Something2: Something, ISomething
{
ISomething_DoSomething() : void implements ISomething.DoSomething
{
Console.WriteLine("Something2.DoSomething");
}
}
public static class Program
{
public static Main() : void
{
((Something() : ISomething)).DoSomething();
((Something2() : ISomething)).DoSomething();
}
}

It can be worked around when you write:
public class Something2: ISomething, Something
However, it is surprising that it works one way but not the other, besides
C# teaches that base class should always come first and then the
interfaces.
