Answer 1

The default constructor which is generated by the O/R-Designer, calls a partial function called OnCreated - so the best practice is not to override the default constructor, but instead implement the partial function OnCreated in MyDataClasses.cs to initialize items:

partial void OnCreated()
{
  Name = "";
}

If you are implementing other constructors, always take care to call the default constructor so the classes will be initialized properly - for example entitysets (relations) are constructed in the default constructor.
