Hi Sal,
Could you please let me know the Essential studio version you are using? This will help us to reproduce the issue here.
The 5.2 version is not fully compatible with VS2008. If you are using prior 5.2, please upgrade to the latest version v6.1 which is fully compatible with VS2008. Please refer to the below link for more information.
