I never start a plugin from the beginning. I always copy a similar plugin and edit it.

I want to add new table and data access

Thank you

Best to look at Nop.Plugin.Tax.FixedOrByCountryStateZip

This not working with 4.30 ?

The database interface has now changed to use Linq2db and Fluent Migrator so it is different to v4.2 which used Entity Framework

unfortunately I get Error and no new entity in database
"FileNotFoundException: Could not load file or assembly 'System.Configuration.ConfigurationManager, Version=4.0.3.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'. The system cannot find the file specified.
Unknown location"

Any tutorial for "Plugin with data access"

Thank you

I don't think this is related to your data access question.  Did you try to load a plugin from another version of nopCommerce?

As Yidna suggested, it's best to look at the source code for an existing plugin.

The error happened after installed the plugin.
But there is no new entity in database..
Is there any step after install the plugin or external code out the plugin ?

Thank you
