We should avoid passing a concatenated or interpolated invalid strings values into a FromSqlRaw or ExecuteSqlRaw method. Since our Version field is of byte array type. Typically you will use AutoMapper map your entity to a DTO model in ASP.NET MVC WebAPI and from DTO to entity when data is submitted. Now you also need to ensure that Version field value is transfered across all layers in your application. OWASP Recommendation: Always use parametrization with raw SQL queries. EF Core will simply throw exception if concurrency happens. NET Core up to 2.2 had a single extension method FromSQL(), which allowed both parametrized and un-parametrized queries.
NET Core 3.1 which allow use to use raw SQL in our EF Core data context. EF Core 6.0 now scaffolds an EF model and entity types that use C nullable reference types (NRTs). There are some key extension methods that are provided in. NET Core Web service APIs using EF Core DTO.īearing this in mind, it would be beneficial to port the raw SQL to using EF Core raw queries until there is an opportunity to upgrade the hard-coded queries to ORM models. Convert the raw queries and stored procedures to logic within backend.Convert the backend from ADO.NET to EF Core and use raw queries.In this case, converting the application to use an EF Core backend can be done in two stages: NET Framework 4.x and ADO.NET libraries that access data directly using raw SQL. There will however be systems and projects written in legacy. The purpose behind using am ORM tool is to provide a layer of abstraction for the developer to be able to access backend data through data context DTOs without using SQL directly. NET Core to allow access to a backend database such as SQL server.

In today’s post I will be discussing how to use raw queries in EF Core and how to use them safely.ĮF Core is the ORM middleware that is used within.
