在Visual Studio Professional 2017中添加app.config（应用程序配置文件）

Question

I can't get the Application Configuration File template to show up under my Add > New Item > Visual C#. I've run a repair. I've uninstalled and reinstalled. I've deleted and added Cache folders. I've run devenv.exe /InstallVSTemplates. Nothing is working. If anyone can tell me specifically what installation elements I should be including, and specifically what type of Project I need to start that might help. I want to create a simple .Net Web Form in .Net and C# and need to include an app.config file.

Answer 1

When you create a new project (depending on the type of project like a web application for example) it will automatically create a template app.config file.

Worst case just make a txt file in notepad and call it [Appname].config

Answer 2

Another way would be to go in the project properties, then the Settings tab. If there are no settings yet, a link should exist in the middle of the empty tab to create a default setting file. Add one Application or User setting and save. Among other things a config file will be created for you too.
