Webview2 change proxy settings multiple times like a rotating proxy

Question

Hi,

I can make the proxy settings of Webview2 at the first initialize but I need to change them multiple time during runtime, when I try to do it again I get this error

System.ArgumentException: 'WebView2 was already initialized with a different CoreWebView2Environment. Check to see if the Source property was already set or EnsureCoreWebView2Async was previously called with different values.'

How can I do that? My code is:

        Dim options As CoreWebView2EnvironmentOptions = New CoreWebView2EnvironmentOptions With {.Language = "en-GB"}
        options.AdditionalBrowserArguments = "--proxy-server=geo.xxxxx.com:12345"
        Dim webView2Environment As CoreWebView2Environment = Nothing
        webView2Environment = Await CoreWebView2Environment.CreateAsync(Nothing, Nothing, options)
        Await WebView21.EnsureCoreWebView2Async(webView2Environment)

Hi, welcome to Microsoft Q&A.

After initialization, CoreWebView2EnvironmentOptions cannot be modified.

It is recommended that you create a new instance of WebView2 to use the new CoreWebView2EnvironmentOptions.

Best Regards.
