Update SQLserver 2012 Data Tool to be an extension
With VS2008 and SQLserver 2008 it was possible to install BIDS as a component of the full VS2008 installation. When VS2010 came along, you had to run VS2010 for most development, but needed a VS2008 shell for BIDS. Now VS2012 is current, SQLserver 2012 uses a VS2010 shell. Since Visial Studio allows extensions, why isn't the BIDS/SSDT compnent developed as an extension - albeit a complex one?
