Data Annotations Table Attribute in EF Core

We use the Table Attribute or Table Name Attribute to specify the table name and schema to the Entity Framework Core.

Table Name Convention

The Default EF Core conventions use the DbSet Property name as the table name or name of the class if DbSet property is not available

Consider the following model.

entity framework core table name convention

The above entity model creates the table with the name Customer in EF Core as shown in the image above. You can override this behavior using the Table attribute. This attribute resides in System.ComponentModel.DataAnnotations.Schema namespace

Table Attribute

Table attribute overrides the default EF Core Conventions, which creates the table with the name same as the Class Name. We apply the attribute to the class and not on the Property.  The EF Core will create a table with the name specified in this attribute.
