inside a DllMain or image initialization function since doing so can cause the application to hang. I tried seraching what this error exactly means, but I am drawing pointless articles, mostly saying that it's just a warning, and I should switch that off in Visual Studio. The other solutions seem to be due to ITunes, or this problem occurring when programming with DirectX. My problem is connected to neither. Can anybody explain, what this actually means? c# loaderlock share|improve this question asked Sep 11 '08 at loaderlock visual studio 2015 14:12 Devdatta Tengshe 1,12942141 I feel with you, I got the same problem, and what surprises me most: my dll is not even managed code, so why/how is it supposed to use managed code on the (non-existent) DllMain?? –Sam Mar 5 '10 at 14:04 I got this warning while attempting to view the contents of a dataset in debug mode.

Posted on November 22, 2010 by Pranav While working with Redemption library, we usually get the following error while debugging the project. Attempting managed execution inside OS https://easyvsto.wordpress.com/2010/11/22/troubleshooting-error-loader-lock-was-detected/ Loader lock. Do not attempt to run managed code inside a http://forums.asp.net/t/1243189.aspx?Managed+Debugging+Assistant+LoaderLock+has+detected+a+problem DllMain or image initialization function since doing so can cause the application to hang. As per Dmitry Streblechenko (Redemption Team), this exception is raised when .NET thinks that a dll that it is loading is doing something that can potentially lock the loader (like circularly loading visual studio dlls etc). Redemption does load the MAPI libraries at the startup, but that is about it. That warning can be safely ignored. Work-Around: We can skip this error by clearing the LoaderLock checkbox in Debug -> Exceptions -> Managed Debud Assistants. Debug | Exceptions | Managed Debug Assistants > LoaderLock (Uncheck this!) Redemption Library is really wonderful loaderlock was detected creation. It helps the developers a lot in handling and accessing some attributes of Outlook Items which cannot be accessed using the API given by Microsoft.
