Want Source Server to Work with Managed Minidumps in Visual Studio? Here’s How!

So you have an awesome minidump your IT guys grabbed with ProcDump. You’ve followed all the rules and have a Symbol Server and Source Server all set up. You open that dump with Visual Studio and BOOM, none of your indexed sources show up. You pull your hair out trying to get your public build sources appear but they never do and it’s just “SRCSRV: The module ‘<<path to the exe file>>’ does not contain source server information.” for everything in the Output window.

Fortunately, a smiling bald guy, Andy Hopper, figured out how to make it all work. Turns out when opening a minidump, the “managed debugging engine tries to verify that each source server enabled assembly is running as a fully trusted assembly from the CLR’s perspective.” Ahh, nothing like security to turn off a feature. The great news is that you can tell the managed debugging engine to stop doing the checks so the Source Server works with the managed minidumps. It’s as simple as setting a registry key. Swipe the registry script below and you are good to go.
