Since moving to Visual Studio 2012 I keep getting loaderlock was detected visual studio 2013 the following error (not every time, but frequently) LoaderLock was detected 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. The error does not occur if I go back to using VS 2010, which makes me fairly certain it is an issue with Visual Studio rather than my code, but I would like someone to confirm that for me! Edit The problem
Loaderlock Was Detected Visual Studio 2008
always seems to occur when the Dispose() method of the dbcontext is called. Here is a screenshot of the Exception Assistant: visual-studio-2012 share|improve this question edited Oct 16 '12 at 12:07 asked Oct 15 '12 at 16:44 Darren 1,65321630 Or, VS2012 is being more careful than VS2010 about unsafe constructs. –nneonneo Oct 15 '12 at 16:52 2 No call stack to look at so hard to help you. In general, LoaderLock tends to produce false warnings. You can turn it off with Debug + Exceptions, MDAs, LoaderLock checkbox. –Hans Passant Oct 15 '12 at 17:17 1 @Hans, there doesn't seem to be a call stack (I've added a screenshot of the Exception Assistant to my post). I assume the problem is in unmanaged code. –Darren Oct 16 '12 at 12:09 1 This also happens with Microsoft Visual Studio Express 2013 for Web using MVC projects which use SQL CE 4.0 and Entity Framework. I have been continuing (F5) and the application still works. I have not found the option to turn the message off in Express yet. –Jeremy Larter May 5 '14 at 13:04 add a comment| 2 Answers 2 active oldest votes up vote 8 down vote accepted I switch this off. As it is warning that the application could hang, if your program doesn't hang, then you're probably fine. share|improve this answer answered Dec 20 '13 at 13:18 harriyott 7,84274787 add a comment| up vote 4 down vote
