Click the Clear All link in the top right to reset all the filters. It might take a minute for the templates to refresh. If nothing shows up then type in the search something like Console
. Also try selecting a different language like C#.
Note that I'm assuming that after you installed VS you weren't told to reboot and that you didn't have VS running, if you updated an existing VS installation. If either of those apply then restart your machine and then try again.
If that still doesn't work then something went wrong while building the template list. Run VS in safemode and see if the problem goes away. If it doesn't then use the Report a Problem tool in the top right corner to report it to MS. They will need to look at the log files to see what might be going wrong.
