Update 1 April 2020: VS 2019 V16.5.2 has been released, and it does appear to fix both problems reported in this post. TL;DR DO NOT update VS 2019 beyond 16.4.0, or you risk breaking the WDK, to the point that it won’t compile anything when Code Analysis is enabled (and you can’t subsequently turn off […]

Three-Plus Years Later… Driver Signing Still Baffles

When I was first named a Microsoft Most Valuable Professional, back in the early 2000’s, I was very proud. Really, I was. There was a cohort of smart, generous, and engaged engineers who were named “DDK MVPs” at the same time that I was appointed. And I am pleased to say that I personally recommended […]
It’s 1809… A New WDK Awaits You… Don’t Be Afraid!
Well, OK… It’s not really 1809 anymore. It’s actually 1810 when I’m writing this. But whatever. There’s a new WDK among us. Before you can install WDK 1809, you’ll need to be running Visual Studio 15.8 and you’ll need to manually install the latest SDK (the version is Windows 10.0.17763.1, which is the 1809 SDK). […]

It’s Baaack: Just My Code, Part II, Breaks Driver Debug Builds (with ANOTHER Workaround)
It’s been two whole weeks since a bug in Visual Studio and the Windows Driver Kit has caused all forward progress on a project to stop. So, it must be time for another bug. Remember this error from VS 15.8: When you try to build a driver with the new “Just My Code” debugging feature […]
