Entity Framework Core and SQL Server 2016 temporal tables

Question

We are using EF Core and SQL Server 2016 for our .NET Core Web API. I am evaluating use of temporal tables and its impact on EF Core code. When I generate the EF model using cmdline then it generates model with appstart, append and mappings in dbcontext. When I do insert/update they fail saying these columns cannot be updated. I had to remove appstart, end from model and dbcontext mapping to make it work. I read there is no interception capability yet in EF Core like EF 6.x.

Please advise about any better solutions for this.

Answer 1

I tried below options and they are working.

1. option 1: removed appstart, append fields from entities and dbcontext mappings and updates/insert started working properly.

2. option 2: decorate period columns with attributes as below.

public DateTime EndTime { get; set; }
