how to replace replace IObjectContextAdapter with IInfrastructure<IServiceProvider> using entity framework core 6

Question

Hi Team,

since IObjectContextAdapter is not supported by entity framework core 6 please suggest the replacement code which supports the below code -

 using (var db = new BloggingContext())
            {
                var blogs = ((IObjectContextAdapter)db)
                    .ObjectContext
                    .Translate<Blog>("pass reader object here", "pass ur dbset/table name here", "MergeOption.AppendOnly");
            }

@Firke, Yogesh (Cognizant), based on my research, it seems that there is no fully equivalent method of the Translate method.

However, you could look at the following workaround to check if it works for you.

            EfContext context = new EfContext();
            var sql = "SELECT * FROM Members WHERE Name = @p0";
            var parameters = new[] { new SqlParameter("@p0", "Test") };
            var result = context.Members.FromSqlRaw(sql, parameters).ToList();

You could use sqlcommand parameters directly, MergeOption.AppendOnly is the default behavior and you don't need to set it.

If you think the workaround does help you, you also could submit the issue in GitHub.

Hope my wordaround could help you.

Best Regards,

Jack
