One day, I tried to create a new WCF Service Application and when I opened the Visual studio and clicked on Add new project, I found that this project option is missing from my Visual studio templates. To add the missing templates to your current installed templates, you need to run the following command on Visual studio command prompt after closing all the instances of the Visual studio.
devenv/installvstemplates
and then Press Enter.
Let the processing to be completed and then open visual studio. Now all the missing templates would be visible under Visual Studio installed templates.
