This happens in this case:

  • ADO.NET provider inherits netstandard2.0 DbDataReader class
  • and doesn't override GetColumnSchema method which returns only column name in the System.Data.Common.DbColumn (DataType is null)

How to fix: if DataType=null resolve column data type with IDataReader.GetFieldType method.
