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?

Answer 1

Another interesting thing I found is that the ReSharper error can be 'satisfied' by doing something like below which is dumb to me. However, as mentioned by many earlier, it still is not a good idea to call virtual properties/methods in constructor.

public class ConfigManager
{
   public virtual int MyPropOne { get; private set; }
   public virtual string MyPropTwo { get; private set; }

   public ConfigManager()
   {
    Setup();
   }

   private void Setup()
   {
    MyPropOne = 1;
    MyPropTwo = "test";
   }
}
