Virtual member call in a constructor

Question

I\'m getting a warning from ReSharper about a call to a virtual member from my objects constructor.

Why would this be something not to do?

Just to add my thoughts. If you always initialize the private field when define it, this problem should be avoid. At least below code works like a charm:

class Parent
{
    public Parent()
    {
        DoSomething();
    }
    protected virtual void DoSomething()
    {
    }
}

class Child : Parent
{
    private string foo = "HELLO";
    public Child() { /*Originally foo initialized here. Removed.*/ }
    protected override void DoSomething()
    {
        Console.WriteLine(foo.ToLower());
    }
}
