P On this page: I’ve been working on Markdown Monster which is a 64 bit application. I found out the hard way today that when you fire up the debugger in Visual Studio it will launch in 32 bit mode by default even if the application would run 64 bit when run directly. In the process I discovered quite a few things of the debugger I wasn’t aware of along with a few suggestions from Kirill Osenkov that were illuminating and that I’ll share here. Before we get into this I want to clarify that in most cases it’s probably OK to be debugging in 32 bit mode when running what otherwise is a 64 bit application.

One of the beauties of a runtime environment like. The framework masks most of those differences for us. That it’s so easy in. NET is actually big deal. I ran into the 32 bit issue while debugging some start up configuration check logic in Markdown Monster.

The application checks whether certain values have been set and if not attempts to set them. As you probably know, system folders and registry paths can vary depending on whether you are running 32 bit or 64 bit.

Folders in particular can be different. Specifically I am using this code to retrieve the program files folder install path in my app: Combine Environment. GetFolderPath Environment.

ProgramFiles , “Markdown Monster” ; which when running on a 64 bit machine should return or whatever localized version thereof: However, when running under the debugger in Visual Studio I’m getting: Both are the same Any Cpu Visual Studio target as the runtime application, but very different results. Uncheck prefer 32 bit The key setting that affects the debugger behavior is the Prefer 32 bit flag which should be disabled if you want to run in 64 bit mode using Any CPU.

If you’re running the ‘raw’ debugger against your process that’s all that needs to happen to ensure your app runs as you’d expect it to run from Explorer or the command window. Even more straight forward though is to force the debug application entirely to 64bit by changing the platform target to x We don’t need you But wait there’s more. The VsHost process acts as a wrapper around the actual application or assembly you are debugging. For the most part the behavior between native and hosted are the same but there are a few differences.

One of them is that the host process will default and stick to 32 bit even if the Prefer 32 bit option is not checked. The only way I could get the host process to work in 64 bit is to explicitly change my project build target to x64 instead of Any CPU which is silly. After a lengthy Twitter conversation with Kirill Osenkeov from the Visual Studio team, I walked away with the impression that it’s best to turn off the VSHost Debugging features in most cases: As Kirill mentions, the host container is a throw back to older Visual Studio days, and there’s actually very little functionality it provides to the debugging process , so you are better off not using it at all unless you need the specific features it provides.

I gladly bypass this extra step. Summary Now with both Prefer 32 bit and Enable the Visual Studio hosting process off, debugging works as expected in 64 bit mode. In most cases the differences between 32 bit and 64 bit are not important in your applications, but regardless I think it’s a good idea to ensure that you are debugging in the same environment you’re expecting to run the application in. It’s easy to overlook some odd behavior that only occurs due to the OS differences.

My case of checking for the Program Files is just one example of that. It took me a while to figure out why the application was not updating the path the way I was expecting to. Especially if you are dealing with the file system and special folder paths, or the registry be very sure that you’re getting data to and from the right places.
