Аксиома с тоской вспоминала то время, когда она была еще теоремой…

Mike, in your example, you’re specifying the type when you call the generic method. That forces it to match the correct signature. I was trying to show that when you don’t specify the type, and you simply use type inference, it chooses the other signature.

So to modify your example, change this line:
DoSomething(i);
to this:
DoSomething(i);

I should have made it more clear how I was calling the generic method.

Did you try this? Or just post the example wrong? There is no way this could be correct. Just fill in the blanks and you can see it:

List i = new List();

DoSomething(i);

static void DoSomething(IEnumerable o)
{
Console.WriteLine(“IEnumerable”);
}

static void DoSomething(T o)
{
Console.WriteLine(“Nope”);
}
