SmartStore.SmartException: 'Guests' role could not be loaded

Hi, 

After I had added few new entitties into EDMX designer I expirience this exception  

SmartStore.SmartException: 'Guests' role could not be loaded

Second question is anywhere any kind of docs available in place to solve following things

1. how to add new entities to solution's DB ?
2. how to add the domain model into the Solution 

Is it model first miogrations ? why in this case the modeller SmartStore.Data.SmartObjectContext.edmx file is excluded from the project smartstore.web. ? 

Really appreciate ASAP response, mission critical

We never tested with the EDMX designer, therefore we do not support it officially. Use Code First approach please.
