This is the fourth release of the LINQ IQueryable Toolkit available on CodePlex. It is a reasource kit for developers building LINQ IQueryable providers. You'll find useful techniques for manipulating general LINQ expression trees, implementing IQueryable providers, and a host of extensible components for building providers that target translation of LINQ expressions into SQL like languages.
This release adds bug fixes, additional providers (MySql and SQLite) and Sessions (that include identity caching, change tracking and SubmitChanges).
The download contains the toolkit both as multiple pre-built DLLs and the source code for building the toolkit and supplied tests. The source code originated from a tutorial series on building LINQ providers located here: http://blogs.msdn.com/mattwar/pages/linq-links.aspx
There is currently no documentation available. Future releases may not retain backward compatibility with what is released here.
If you are downloading this toolkit from any place other than http://www.codeplex.com/IQToolkit you may not be getting the official release.
