Hi,

If I define a Complex Type in an abstract class in Code First, values from this complex type are never saved to the database.

Below a project test :

Hi Walid,
 
You did not decorate the Creation property with the [DataMember] tag.
Doing so will persist the data.

Hi,
 
Thank silvio, you were right.
 
Although it's not really clear for me when I should or not put the DataMember attribute with Devforce.
Reading the documentation, I understood I don't have to put the DataMember atttribute all the time, only when at least one property has reduced access in the class.
 
In this exemple, I don't see why it is required. Is it because it's a complex type ?

Hi Walid,
 
It's not because the property is a complex type, but it's because you are using the [DataContratc] tag in the BaseEntity class itself.
For this reason, you will need to decorate the property with [DataMember].
