Extend ASP.NET MVC for Asynchronous Action
Numerous new features come into people’s eyes since ASP.NET 2.0 and asynchronous request handling is one of the most important parts. It reduces the working thread number by the async mechanism based on IO completion port when processing IO bound request and improves throughput of web sites significantly (please refer to the theory analyzing and benchmarks if you can read Chinese :P). But the current version of ASP.NET MVC doesn’t support async actions and that’s just ‘the missing key feature’ I mentioned before. I gave a so-called solution that introduced the async action to ASP.NET MVC in my session of TechED 2008 China but it’s full of limitations and inappropriate for production use.

LINQ to SQL Extension: Batch Deletion with Lambda Expression
Batch deletion in the O/R Mapping frameworks is always depressing. We need to query all the entities we want to delete from the database, pass them to the DeleteOnSubmit or DeleteAllOnSubmit methods of DataContext, and finally invoke SubmitChanges to delete the records form database. In this case, we will cost an additional query and send lots of "DELETE" commands to database. How wasteful!
