get_AdditionalBrowserArguments

AdditionalBrowserArguments can be specified to change the behavior of the WebView.

public HRESULT get_AdditionalBrowserArguments(LPWSTR * value)

These will be passed to the browser process as part of the command line. See Run Chromium with Flags for more information about command line switches to browser process. If the app is launched with a command line switch --edge-webview-switches=xxx the value of that switch (xxx in the above example) will also be appended to the browser process command line. Certain switches like --user-data-dir are internal and important to WebView. Those switches will be ignored even if specified. If the same switches are specified multiple times, the last one wins. There is no attempt to merge the different values of the same switch, except for disabled and enabled features. The features specified by --enable-features and --disable-features will be merged with simple logic: the features will be the union of the specified features and built-in features, and if a feature is disabled, it will be removed from the enabled features list. App process's command line --edge-webview-switches value are processed after the additionalBrowserArguments parameter is processed. Certain features are disabled internally and can't be enabled. If parsing failed for the specified switches, they will be ignored. Default is to run browser process with no extra flags.

get_AllowSingleSignOnUsingOSPrimaryAccount

The AllowSingleSignOnUsingOSPrimaryAccount property is used to enable single sign on with Azure Active Directory (AAD) resources inside WebView using the logged in Windows account and single sign on with web sites using Microsoft account associated with the login in Windows account.

public HRESULT get_AllowSingleSignOnUsingOSPrimaryAccount(BOOL * allow)

Default is disabled. Universal Windows Platform apps must also declare enterpriseCloudSSO restricted capability for the single sign on to work.

get_Language

The default language that WebView will run with.

public HRESULT get_Language(LPWSTR * value)

It applies to browser UIs like context menu and dialogs. It also applies to the accept-languages HTTP header that WebView sends to web sites. It is in the format of language[-country] where language is the 2 letter code from ISO 639 and country is the 2 letter code from ISO 3166.

get_TargetCompatibleBrowserVersion

The version of the Edge WebView2 Runtime binaries required to be compatible with the calling application.

public HRESULT get_TargetCompatibleBrowserVersion(LPWSTR * value)

This defaults to the Edge WebView2 Runtime version that corresponds with the version of the SDK the application is using. The format of this value is the same as the format of the BrowserVersionString property and other BrowserVersion values. Only the version part of the BrowserVersion value is respected. The channel suffix, if it exists, is ignored. The version of the Edge WebView2 Runtime binaries actually used may be different from the specified TargetCompatibleBrowserVersion. They are only guaranteed to be compatible. You can check the actual version on the BrowserVersionString property on the ICoreWebView2Environment.

put_AdditionalBrowserArguments

Set the AdditionalBrowserArguments property.

public HRESULT put_AdditionalBrowserArguments(LPCWSTR value)

put_AllowSingleSignOnUsingOSPrimaryAccount

Set the AllowSingleSignOnUsingOSPrimaryAccount property.

public HRESULT put_AllowSingleSignOnUsingOSPrimaryAccount(BOOL allow)

put_Language

Set the Language property.

public HRESULT put_Language(LPCWSTR value)

put_TargetCompatibleBrowserVersion

Set the TargetCompatibleBrowserVersion property.

public HRESULT put_TargetCompatibleBrowserVersion(LPCWSTR value)
