Entity Framework POCO default constructor

Is it okay to have default constructor which sets some default values like:

publi开发者_运维百科c class BetScreenshot
{
   ...

   public BetScreenshot()
   {
       CreationDateTime = DateTime.UtcNow;
       StatusEnum = BetScreenshotStatus.NotProcessed;
   }
}

My first bad feeling is that these properties might be marked as modified during EF entities instantiation. But may be there is something else?

Yes it's ok to initialize properties. Effectively during construction using a parameterless constructor, the fields of the type are initialized to the default anyway. You're just choosing a different default. It's a pretty common practice to new up child entities and collections, but there's no reason simple properties can't be initialized. I do this for several entities and EF correctly recognizes the object as new/unmodified.
