@MaxWang-MS Here is what I am using   I tried re-importing the package again, but didn't helped.

@RogPodge My scenario was little different. I was upgrading the project from MRTK v2.5.3 to v2.8.0 steps by step. The upgrade went smooth till version v2.7.3 but got the error...

@Hendy Is there any temporary fix for this problem? What if I change save to another format instead of CSV. Does that solve this issue?

@valfrid-ly I have gone through the test case explaining [reference map](https://github.com/tmsmith/Dapper-Extensions/blob/master/DapperExtensions.Test/Data/Common/Inheritance.cs). However, I am unable to make it working. Do you have any thoughts on why it's not working?

Thank you @valfrid-ly. Much appreciated for the reply. Let me try the same and will keep you posted.
