Oops! Custom mapping is currently not supported with self-hierarchy at this moment. about entityframework-extensions HOT 6 CLOSED

Hello @NicoKno ,

I talked with my developer, and you are right. This is a scenario that is currently not yet supported with the new IncludeGraph introduced in the v7.100.0.0.

Our new IncludeGraph greatly improves the performance for self-hierarchy but is still incompatible with custom mapping in this case. That's something we will try to support soon.

You can learn more about the new IncludeGraph here: https://entityframework-extensions.net/v7-100-0-0-include-graph

LegacyIncludeGraph

You can use the LegacyIncludeGraph option, which should work like the IncludeGraph in the v5.1.21.

context.BulkInsert(list, options => {
	options.LegacyIncludeGraph = true;
});

It will be a lot slower but at least will be compatible with self-hierarchy with custom mapping (at this time, commands were generated by EF Core).

Let me know if that solves your issue.

Best Regards,

Hi Jon,

thats nice to hear. I can try and refactor my code to use LegacyIncludeGraph.
As we are interested to also use the new features. What is actually meant by self-hirachy and especially CustomMapping.
I don't remember setting up any column mapping of any kind. The only thing we do is using a ColumnPrimaryKeyExpression.

Would there be some way to simply deactivate CustomMapping so I can see where I use it?

Could you please elaborate?

Hello @NicoKno ,

I will have a meeting with my employee who worked on this next Monday. So I will provide you soon a more accurate answer about it.

Hello @NicoKno ,

I forgot to mention that using the ColumnPrimaryKeyExpression is considered "custom mapping" for us in this case. That is a point we will discuss about the challenge (if any) to support at least a custom key.

I implemented LegacyIncludeGraph in my codebase and it works now. Thanks for the heads up.

Hello @NicoKno ,

Just to let you know, starting with the v7.100.0.4, it's now possible to use the EF Core Bulk Insert to set custom key properties as long as you do not use the Foreign Key such as BossID in an Employee table.
