Entity Framework error: Cannot insert explicit value for identity column in table

Question

I\'m getting this error on EF.

Cannot insert explicit value for identity column in table \'GroupMembers_New\' when IDENTITY_INSERT is set to OFF.

Answer 1

I encountered the same problem and error message in my AspNetCore 2.x application. The only way I could solve it was by removing this line in the ModelBuilder.Entity method of the DbContext class:

// remove: entity.Property(e => e.Id).ValueGeneratedNever();
