This is the first 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.
The download contains the toolkit both as a pre-built DLL 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/archive/2007/07/30/linq-building-an-iqueryable-provider-part-i.aspx
There is currently no documentation available. Future releases may not retain backward compatibility with what is released here.
