If you are working with project or solution in visual studio 2015, then you will not see the “Show All Files” button in the solution explorer. Here we will see where we can see the button.
You can refer to the fig below that if you will select the solution explorer you will not be able to see the Show All Files button.
By default, the Show All Files button will not appear if you will select the solution explorer. You can see the button when you will select the Project, or any files or folder or any item inside the project.
So select the project and you will be able to see the Show All Files button like below.
Hope this will be helpful.
