Writing a LINQ provider is a required skill for framework developers in the next few years. In the future, all. Net class libraries that expose data storage will require the support of LINQ. With the recent release of. Net 3.5, this issue will be put on the agenda.
To give developers, especially those who write providers, a simpler understanding of how LINQ works, Bart De Smet creates a standard query operator called linqsqo (LINQ standard query operator). The description is as follows:
This is my first LINQ-related project since the first release of LINQ at the PDC 2005 conference. This project includes a customized Implementation of linqsqo used in LINQ. More specifically, it is a clone of the enumerated static class. You can find all its extension methods in the system. LINQ namespace in system. Core. dll. In this way, you can think of it as the equivalent of a LINQ to objects. The initial goal of this project is to allow developers to better understand how LINQ works. AndSource codeTogether, we also provide 148 unit tests to process basic tests for all query operators.
Bart released the RTM version of linqsqo on codeplex.
