推荐答案

实施OnCreated事件实体是我已经找到了解决方案。我有一个GUID属性，我想填充。默认情况下它被填充全零（00000-0000-00000-等）。通过添加下面的实体是我部分类，我能够处理这一问题。

Implementing the OnCreated event for the entity is the solution I have found. I had a Guid property that I wanted to be populated. By default it was being populated with all zeros (00000-0000-00000-etc). By adding the following to my partial class of the entity I was able to deal with the issue.

partial void OnCreated()
{
    Guid = Guid.NewGuid();
}
