Microsoft has this neat mailing list called “Spot the Bug” where developers can send interesting snippets of code that look correct but actually have subtle bugs in them.  The puzzles are a lot of fun and I’ve always thought it’d be a fun thing to try here on the team blog.  Over the past year or so I’ve been keeping a list of interesting...

In my last post, I talked about the hidden costs that can occur whenever you call out to methods, particularly in loops.  In looking at my examples, reader KG2V commented that another thing that folks need to be aware of is avoiding the assumption that the world (or, in this case, a list) is a static thing.  It’s a good point and it...

About two years ago I posted some code that shows how to dynamically construct LINQ queries at runtime.  On average there's a couple questions per month about trying it in some edge case, and usually the support already exists within the API.  Recently though someone posted a question that has to do with Datasets and Joins that raised som...

In my post “M. G. Phone Home,” I discussed how to write a simple phone application for Windows Mobile, using Visual Basic, which accesses the Bluetooth service.  What I didn’t discuss was how to deploy it to the phone via CAB.  Since I purchased a new phone yesterday (a Samsung Saga, running Windows Mobile 6.1), and I&rs...
