I\'m looking for an ORM that offers complete or near-complete LINQ support.

LINQ to SQL
- Supports about everything inside of LINQ (.Contains, Math.Log, etc)
- C

    Genome.

    Genome O/RM uses LINQ to generate data access layers connecting relational database systems such as Microsoft SQL Server, Oracle and IBM DB2 to your .NET enterprise applications.

  • Llblgen seems to have pretty good linq support. Frans has a whole series of blogs posts on his development of it http://weblogs.asp.net/fbouma/archive/2007/09/11/developing-linq-to-llblgen-pro-day-0.aspx

  • Try DataObjects.NET. I'm one of the DO developers. And my latest activity within that project is to implement LINQ for DataObjects. So I could describe it briefly:

    • Supports almost all LINQ methods except Last/LastOrDefault/Aggregate/Reverse/TakeWhile/SkipWhile etc. and methods that has .NET specific arguments - such as IComparer (nobody supports them).
    • Almost all string and Math methods supported (and you have ability to write your own function mappings!).
    • Complex scenarios with GroupBy\SelectMany\Contains\Single\etc. in subqueries and correlated subqueries are supported.

    We have about 1000 tests of LINQ implementation and 99% of them are passed. So I can say that current implementation is close to EF. Some methods do not work with EF, some with our framework. Check this brief description http://www.x-tensive.com/Products/DO/.
