Attempting managed execution inside OS Loader lock

I am trying to link my VB.NET / C# application with Tally using RTSlink DLL. But I get this error while calling Open() function :-

"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. "

Solution 1
1. Go to Debug/Exceptions
2. Open up the Managed Debugging Assistants node on the tree and scroll down till you find LoaderLock and uncheck it.

After this recompile the project.
