Entity Framework Core is a complete rewrite from the “classic” Entity Framework, building on the new multiplatform .NET Core framework and adding the ability to connect to nonrelational data sources while keeping the features that made Entity Framework Code First so popular. In Entity Framework Core Succinctly, join Ricardo Peres to explore this new version of the O/RM, from getting set up to avoiding common traps.

در صورتی که با همین یوزر من به سیستم مدیریت MSSQL لاگین میکنم
یک نکته دیگه اینکه من با همین رشته اتصالی دارم به یک دیتابیس دیگه هم لاگین میکنم
