After VS2010 is installed and vb.net compilation is opened for the first time, an error message may appear: "Attempting managed execution inside OS LoaderLock. Do not attempt to run managed code inside a DllMain or image initialization function since doing so can cause the application to hang".The solution is as follows:

Select "Debug "---> Select "Exceptions" ---> Select "Managed Debugging Assistants" ---> Remove the check before "LoaderLock" ---> Click "OK". Recompile the VS2010 and the problem has been solved.
