Fixing 'Managed Debugging Assistant LoaderLock' Error
Getting error while developing a software with DirectX API using latest Visual Studio? This might be the solution
Recently I’ve been doing some tasks that require me to build OpenDental from source code. It is a Dental Practice software with some graphical features. They are developing those graphical features by using using DirectX API.
This software have been developed since a long time ago so I expect that there will be some incompatibility if I’m using latest Visual Studio. In my case, I use Visual Studio 2017 v15.8.4 to compile and run the program.
I already followed their documentation on how to build the software from source like checking out svn repository, copying
NHunspell to binary folder, etc.
I open the solution file and try to build it.
And then I got an error after I hit the build button.
Here is the error message I received.
Managed Debugging Assistant ‘LoaderLock’ : ‘DLL ‘C:\WINDOWS\assembly\GAC\Microsoft.DirectX.Direct3D\1.0.2902.0__31bf3856ad364e35\Microsoft.DirectX.Direct3D.dll’ is attempting managed execution inside OS Loader lock. Do not attempt to run managed code inside a DllMain or image initialization function since doing so can cause the application to hang.’
If you also have similar error message like this, then you’re in a right place.
Luckily, it’s easy to fix this problem. You just need to uncheck an option in Exception Settings.
To do that, open your Visual Studio window.
Exception Settings ( or with keyboard shortcut Ctrl + Alt + E ).
Managed Debugging Assistants, find and uncheck
That’s it, now you can build and run the project normally. Hopefully it’ll also solve your problems.
Thanks for reading and happy coding!
