After installing the solution:

• added refrence of "Smartstore.Data.SqlServer" to "Smartstore.Web" project
• initated the DB.

I wanted to make some changes and update the DB.

I have selected in package manager console the "Smartstore.Core" as default project and run "add-migration [name of the migration]"

 

I have received following error:

 

An error occurred while accessing the Microsoft.Extensions.Hosting services. Continuing without the application service provider. Error: Could not load file or assembly 'C:\Users\shira\.nuget\packages\microsoft.entityframeworkcore.tools\7.0.8\tools\netcoreapp2.0\any\Smartstore.Data.SqlServer.dll'. The system cannot find the file specified.

Unable to create an object of type 'SmartDbContext'. For the different patterns supported at design time, see https://go.microsoft.../?linkid=851728

 

Any Advice?

"added refrence of "Smartstore.Data.SqlServer" to "Smartstore.Web" project"

 

This is neither necessary nor recommended.

 

"initated the DB."

 

Whatever is meant by this, the database is created automatically during the Smartstore installation. This includes schema changes that are initiated by modules. It is neither necessary nor recommended to interfere there.

 

"I wanted to make some changes and update the DB."

 

Read and follow the instructions in the developer guide:

https://smartstore.g...ed-with-modules

https://smartstore.g...a-domain-entity

https://smartstore.g...base-migrations

 

Take a look at sample modules and their data migration, e.g. here.
