I have been paying attention to three open-source Orm. One is nhib.pdf, the other is gentle. net, and the other is ibatis.net.
Nhib.pdfIt's a pity that it is too complicated to use and has a high threshold.
Gentle. netIt is a persistence layer based on the. NET reflection mechanism. It is relatively simple to use, and the current version (1.2.5) is relatively stable.Ibatis.netIt is called a semi-automated Orm. SQL statements are directly configured in XML instead of generated at the persistent layer. This method should be very flexible, and the user's control is relatively strong. After all, SQL statements are self-written and do not need to worry about the performance of SQL statements generated by Orm. However, when I see the configuration file, it seems useless to write a lot of extra XML.CodeIt is not as straightforward as using data access block.
