Public Property AdditionalBrowserArguments As String

Property Value

String

Remarks

The arguments are passed to the browser process as part of the command. For more information about using command-line switches with Chromium browser processes, navigate to [Run Chromium with Flags](https://aka.ms/RunChromiumWithFlags). The value appended to a switch is appended to the browser process, for example, in --edge-webview-switches=xxx the value is xxx. If you specify a switch that is important to WebView functionality, it is ignore, for example, --user-data-dir. Specific features are disabled internally and blocked from being enabled. If a switch is specified multiple times, only the last instance is used.

A merge of the different values of the same switch is not attempted, except for disabled and enabled features. The features specified by --enable-features and --disable-features will be merged with simple logic:

  • The features are the union of the specified features and built-in features. If a feature is disabled, it is removed from the enabled features list.

If you specify command-line switches and sets this property, the --edge-webview-switches value takes precedence and is processed last. If a switch fails to parse, the switch is ignored. The default state for the operation is to run the browser process with no extra flags.
