Hello @zhanfuzhi ,

What's the column name of your primary key in your database? Could it be possible the case sensitive is not the same?

[zhanfuzhi]

The ABP framework does not support EF BulkInsert ，Help Me

[JonathanMagnan]

Hello @zhanfuzhi ,

Can you provide a runnable project/solution?

Looking at your code here (https://github.com/zzzprojects/EntityFramework-Extensions/issues/227), it looks to support it. So we probably missing something in your question.
