Entity Framework vs Nhibernate

NHibernate vs. ADO.NET Entity Framework

NHibernate may be more mature. That does not necessarily mean it is a "better" solution. Having used it at my job for some time, I would personally prefer to use almost anything than NHibernate (even straight SQL, if migration were remotely feasible). The number of error messages thrown by NHibernate that don't mean anything (or that do mean someth...

NHibernate vs. Entity Framework 4

A lot has been talked about Entity Framework first version on the web (also on stackoverflow) and it is clear that it was not a good choice when we already have better alternative like NHibernate.

EF vs NHibernate vs Drapper ORM

The problem with "big" ORM tools such as EF or NHibernate, is that (exagerating?) 99% of developers are overwhelmed with mastering simply how to make it work; they don't have time to figure out how to make it perform. Worse, making these tools perform properly usually boils down to having competent SQL/Database design and tuning skills - which wea...
