1|0 .NET ORM Preface
Why write this article?
I hope to optimize the search engine for SEO so that more Chinese people can know and use it. At present, Baidu search .NET ORM is all sqlsugar. I am speechless. The first thing everyone enters into the group is to compare them. They have to answer, answer and persuade them every day. It is very difficult to convince the tags to be the same type of .NET ORM with great reputation and many users. FreeSql does not want to be its own shining gold. I hope to write this complete .NET ORM comparison in 2020. For those who are ready to use FreeSql, it would be great to be ranked on the Baidu search engine.
I would like to invite friends who are using CSRedisCore and FreeSql to forward this article with their fingers, and add a link to the original text to point to this article, thank you! QQ group: 4336577 (full), 8585575 (online), 52508226 (online)

FreeSql .NET ORM supports MySql/SqlServer/PostgreSQL/Oracle/Sqlite/Firebird/Dameng/Renda Jincang/Shenzhou General/Access.
.NET ORM has its own housekeeping skills. This article mainly lists and compares the functions provided by FreeSql. If you offend, please forgive me, and you are welcome to make functional suggestions to FreeSql.
The depth level of each function implementation is different (for example, EFCore supports SqlServer 2012, FreeSql supports SqlServer 2005), it is difficult to compare thoroughly. Tips:
- The functions compared in this article FreeSql are basically provided for each database, unlike EFCore which favors SqlServer
- This article only compares the official functions (not including third-party extensions)
