Where is user.config loaded from during Visual Studio debugging

问题

I have an application that reads from a user settings file, typically stored in Users/{username}/AppData/Local/{publisher}/{app}/{version}/user.config. I want to test making changes directly to the file, not through the Visual Studio properties editor.

I found this answer to a different question that points to where the application is supposedly loading the file from, but it doesn't seem to exist when I check during a debug session in Visual Studio.

For example, when I run the following in the Immediate window when stopped on a breakpoint, it fails to find the file.

System.IO.File.Exists(System.Configuration.ConfigurationManager.OpenExeConfiguration(System.Configuration.ConfigurationUserLevel.PerUserRoamingAndLocal).FilePath) //returns false

My reason for wanting to find this file during debugging is that I have received reports of the config file being corrupted and crashing the application in production. I'm sure that I can return that file to a default state, but I want to actually reproduce the problem in a debug environment.

How can I find the settings file loaded by Visual Studio?

回答1:

I'm not quite sure what changed between when I posted this question and now, but today the code in my question returns true. But to answer the specific question I asked, the user.config file was in a very similar path to a standard installed application.

Standard application:

Users/{username}/AppData/Local/{publisher}/{app}/{version}/user.config

Visual Studio debug application:

Users/{username}/AppData/Local/{publisher}/{app}.vshost.exe{some_hash_value}/{version}/user.config
