Public EF6.Book FirstOrDefaultWithEf6() => For this test I will use a simple FirstOrDefault() to grab the top 1 Book record from each database. The first comparison is a very common scenario in Entity Framework: fetching a single record from the database. Protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder) => Integrated Security=True Database=EfCoreBookDB MultipleActiveResultSets=true " I seeded both SQL Server databases with similar sets of data as the previous post. The data model will be the same Books SQL Server database I created previously in my post about Entity Framework performance considerations. If you see a mistake on my part, or have a suggestion, feel free to make a pull request! The Data Entity Framework Core, feel free to visit my Github page for the project here. If you're interested in the source code I used in benchmarking Entity Framework 6 vs. To see my previous blog post that served as an introduction to BenchmarkDotNet, click here. Entity Framework Core, I find it to be the perfect tool. For scenarios such as Entity Framework 6 vs. NET CodeīenchmarkDotNet has become my defacto decision making tool when it comes to performance testing my. It might be worth revisiting these benchmarks soon. Entity Framework Core 3.1, the long term support (LTS) version of Entity Framework Core, will once again target the netstandard2.0. NET Framework, but unfortuntely Entity Framework Core 3 targets the netstandard2.1, which won't work with the full. NET framework seeing how there's probably a lot of Entity Framework 6 applications out there running on the full. Another useful test might be benchmarking on the older. NET Core 3 console app that references both EF6 (6.3.0) and EF Core 3 (3.0.1). Each DbContext will be connecting to its own database on my SQL Server LocalDB instance. Finally, each of these class libraries, which contain a functionally equivalent DbContext and data model, will be tested against each other in a console app using BenchmarkDotNet, a very powerful benchmarking framework that will help us finely measure performance. Each class library will contain a package reference to EF6 and EF Core 3 respectively. To set up this benchmark, I will create two. Using real benchmarks, I will use worked examples to demonstrate whether Entity Framework 6 or Entity Framework Core performs the best. One of the most touted benefits EF Core has over EF6 is improved performance. Entity Framework (EF) Core was a complete rewrite from the tried and tested EF6.
