How to use browser Incognito Mode in visual studio when Run a web project

Not the answer, but in case someone stumbles upon this question, looking for the Visual Studio Code solution, this worked for me:

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "chrome",
            "request": "launch",
            "name": "Chrome: localhost",
            "url": "http://localhost:8080",
            "webRoot": "${workspaceRoot}/app"
        },
        {
            "type": "chrome",
            "request": "launch",
            "runtimeArgs": [
                "--incognito"
            ],
            "name": "Incog Chrome: localhost",
            "url": "http://localhost:8080",
            "webRoot": "${workspaceRoot}/app"
        }
    ]
}

However, this does not currently work using the Firefox debugging extension with the -private-window argument. Hope it helps.

For Visual Studio 2017

1. Select button that usually says IIS Express
2. Click the down arrow
3. Select Browse With...

4. Click Add...

5. Next to Program write the path to Google Chrome, eg. C:\Program Files (x86)\Google\Chrome\Application\chrome.exe
6. Next to Arguments write --incognito
7. Next to Friendly name write Google Chrome (Incognito) (or whatever suits your needs)

8. Click OK
9. Select your friendly name from before (eg. Google Chrome (Incognito)) and click Set as Default

Now when you click the play button next to IIS Express, Google Chrome starts in Incognito mode.

It is very simple using visual studio 2015 / 2017 / 2019. You just need to add --incognito as command line switch and name the browser something like Google Chrome - Incognito.

That you can do using Browse With.. option in visual Studio.

Step-1:

Step-2:


Note: You can do the same thing with Firefox and Internet Explorer. Here I'm adding Internet Explorer with the -private option.

For
Google Chrome : "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --incognito
Firefox : "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -private-window
Internet Explorer/Microsoft Edge : "C:\Program Files\Internet Explorer\iexplore.exe" -private
