I use Solutions a lot in SQL Server Management Studio (SSMS), and you should be aware of this simple tip: If you want to open a Solution without having to open SSMS and then jumping through all the menus, just double-click the solution name in the Windows folder. It will automatically open the Solution and SSMS at the same time.

This tip, by the way, also works with any .SQL files, unless you've installed another product that has that file associates with the .SQL extension.
