Many Visual Studio users have a solution tree structure with multiple projects and solution folders that are organized as a deep hierarchy. To avoid visual pollution, users want only those projects expanded that are being actively developed (often with many of the project’s child nodes recursively collapsed). To accomplish this task, they have to manually collapse each node recursively – an onerous chore if one has a deeply nested solution tree. The Collapse Selection in Solution Explorer extension addresses this particular issue by enabling the user to recursively collapse multiple nodes with a single click.
Simply select the node or nodes you would like to recursively collapse and press the button on the Solution Explorer toolbar or use the keyboard shortcutCtl + Alt + Num(-) (Num(-) is the "-" key on the numeric keypad). Select the solution node to recursively collapse all nodes in the Solution Explorer.
