tmsmith / Dapper-Extensions

Dapper Extensions is a small library that complements Dapper by adding basic CRUD operations (Get, Insert, Update, Delete) for your POCOs. For more advanced querying scenarios, Dapper Extensions provides a predicate system. The goal of this library is to keep your POCOs pure by not requiring any attributes or base class inheritance.

Dapperextensions: error mapping datetime (DB) to DateTimeOffset (entity); However, dappercontrib mapping is normal.

System.Exception: Invalid cast from 'System.DateTime' to 'System.DateTimeOffset'.: An error occurred while mapping the value '2021/12/17 3:07:00' of type System.DateTime to the member name 'Birthday' of type System.DateTimeOffset on the MultiTenantDemo.Entity.User class.

Where is the custom field mapping function

Please send your POCO and Mapper to check.
