Since ReaderWriterLockSlim is a .net 3.5 addition (in System.Core), building on .net 3.5 is required to fix this issue

> ReaderWriterLock should be replaced with ReaderWriterLockSlim according to Microsoft for performance and simplification reasons.
> MSDN: http://msdn.microsoft.com/en-us/library/system.threading.readerwriterlock.aspx
> The .NET Framework has two reader-writer locks, ReaderWriterLockSlim and ReaderWriterLock. ReaderWriterLockSlim is recommended for all new development. ReaderWriterLockSlim is similar to ReaderWriterLock, but it has simplified rules for recursion and for upgrading and downgrading lock state. ReaderWriterLockSlim avoids many cases of potential deadlock. In addition, the performance of ReaderWriterLockSlim is significantly better than ReaderWriterLock.
