EF Core column name from mapping api

entity-framework-core

Question

In EF 6.1 the mapping API was introduced where we could finally get access to table names and column names. Getting the table name is a very nice change in EF Core, but I have not yet uncovered how to get the column names.

For anyone interested here is how I got the table name in the latest version (RC1)

context.Model.FindEntityType(typeof(T)).SqlServer().TableName

What is the current method to get column names or is this not available yet?

This version doesn't assume SqlServer and can work as well with Npgsql provider as long as data store is relational.

var columnNames = dbContext.Model.FindEntityType(typeof(T))
                  .GetProperties().Select(x => x.Relational().ColumnName);
