Another question is how the samle data is populated to database ? 

Appreciate any help ?

I'm talking about Store source code not the Community 

Hello,

I'd like to help you, but your posts are a little confused.

If Smartstore.NET was installed correctly, a settings.txt exists under \app-data\tenants\default. The content will be correct because the file was just created by Smartstore.NET during the installation.

You can specify whether to create sample data before the installation.

Ohh. Thanx.. 

Tell me please which approach do you use in the solution :
Model First, Database First or Code First ? 

really appreciate help 

you have to set Smartstore.Web as the startup project.

model first

Code First.

Correction

With all due respect, I think the answer to OP's question regarding the EF approach should be Code First on. This is based on my limited review of your projects, so sorry if I missed something.

A valid connection string in the settings.txt file is a prerequisite. Furthermore, during initialization, our custom DbContext checks the existence of some important tables.
