Using VS Express 2013 for Web on Windows 7 Professional, the Design, Split and Source views only appear when I first start VS, and vanish after awhile of coding. I tried right-clicking on Default.aspx (View Designer, View Markup, etc.), doing a refresh, closing and reopening the solution, but the only way I can see the design tabs again is to restart VS.
I don't use Design that much, but I definitely need to see Source.
Anyone know of a fix for this?
