Testing: GC Sanity Checks in Whidbey

Bringing an end to the posts on decompositions of numeric ranges into validating regular expressions.

I've posted quite a few items covering the process of decomposition. Most of the examinations are textual only and cover the process of generating decompositions by hand. I've since issued a challenge for the creation of an algorithm that would automatically...

Asynchronous Regular Expressions using the ThreadPool and a cancellation model.

There are probably numerous ways to shoot holes in this class, but this is a 30 minute attempt at providing an asynchronous framework for running regular expressions. The crux of the model is to allow for cancellation of long-running expressions that...
