Is Entity Framework the best performing option for PostgreSQL and .NET applications?

Updated on Monday, April 15, 2017
Abstract
Object-relational mapping (ORM) solutions provide a virtual layer between actual application code and backend database (DB) being used in an application via create, read, update and delete (CRUD) operations. PostgreSQL has been one of the top notch backend DB being deployed with Microsoft .NET applications worldwide. This experiment will be targeting various ORM solutions which may perform well with Microsoft .NET platform and PostgreSQL as backend. The list of ORM solutions that will be evaluated includes NHibernate (NH), OrmLite, MicroLite, Entity Framework (EF), LINQ to PostgreSQL, I-Nercya EntityLite Core, Symbiotic Micro ORM x64, LLBLGen Pro, Uni.ORM, and FluentData. It’s very much true that one may be easy to setup and consume than the other, but scope of this experiment will be limited to analyzing these ORM solutions based on how fast they are able to perform CRUD operations with PostgreSQL and .NET.

  1. one more contender - http://vita.codeplex.com. Supports Postgres, full LINQ, and will certainly beat EF and NH in performance - especially update/insert - it has batch mode, executing all changes in one roundtrip

  4. Hi, you mentioned that "PostgreSQL has been one of the top notch backend DB being deployed with Microsoft .NET applications worldwide." Do you have any examples of companies or projects using this tech stack?

    1. Please refer to no of downloads on NuGet for related stuff. e.g, as of 11/6/15 , no of downloads for nuget packages realte to this combination:

      Neverthless, purpose of this article is not to convince you: go and use PostGreSQL with .Net,but one step further : if you choose this combination then what ORM to choose of the two most popular.

      Thanks
