> Currently we invoke native platform using "Marshal.GetDelegateForFunctionPointer". 
> This is the least efficient way to call external code. What can be done to improve it:
> 1) Add [SuppressUnmanagedCodeSecurity] attribute.
> 2) Use P/Invoke instead. We do not use it now because we unpack native library in runtime into some temp folder, while PInvoke searches for libraries in predefined file system places. Need to evaluate whether we can switch back to P/Invoke somehow.
