title: ctrl+shift+space Not Working in Visual Studio
body: <p>Starting about a week ago (11/30/2017) I noticed that ctrl+shift+space was no longer working in visual studio (any version) to show the parameter info of a method invocation. I did quite a bit of searching to figure out the problem, especially here on SO, and I couldn't find a solution. I also double-checked my VS settings and even reverted back to an old settings file.</p>
