When I use the "find in files" Window in Visual Studio 2017 and select "entire solution" to search in, the search does not work: the result window opens and the options for the search are listed, but nothing else happens or is listed in the result window.
When I select "all opened files" or "current window" instead of "entire solution", search works without problems.
It does not depend on the solution opened: I tried to search in several different solutions and also in a completely new one.
I already tried the suggestions here: Visual Studio "Find in Files" does not work but nothing worked. Maybe there is something else to try?
In the end, I re-installed Visual Studio 2017 and that solved the problem.
