How to install extensions in WebView2 prerelease v1.0.2065?

[Nocturna22]

Hello, currently I am trying to install an extension. I try to check if extensions are allowed, but I do not find the function.
So I tried to install the extension:

WebView2_Main.CoreWebView2.Profile.AddBrowserExtensionAsync("C:\Users\xxxx\Desktop\xxxx\chrome\xx-xxt-xxx\xxxxxx_v7.1.zip")

I also tried unzipping the zip file and specified the folder. There is a manifest.json in there.
Also I tried to get a list of all installed extensions:

MsgBox(WebView2_Main.CoreWebView2.Profile.GetBrowserExtensionsAsync.ToString)

But that didn't work either...
So how do you install an extension?
And in which path is the extension installed then?

I'm able to install extensions. First, you must set CoreWebView2EnvironmentOptions.AreBrowserExtensionsEnabled to true. Then, call CoreWebView2.Profile.AddBrowserExtensionAsync("folder containing manifest.json").

Thank you very much. I use the control via the designer. I have some difficulties to set the options of the control.

did you initialize the control via code, or via the designer?

[mikeduglas]

via code, like this:

CoreWebView2EnvironmentOptions options = new CoreWebView2EnvironmentOptions(customSchemeRegistrations: csRegistrations);
options.AreBrowserExtensionsEnabled = true;

CoreWebView2Environment env = await CoreWebView2Environment.CreateAsync(
  cp?.BrowserExecutableFolder,
  cp?.UserDataFolder,
  options);

await webView.EnsureCoreWebView2Async(env);

Yes this looks like my code.

Dim options As CoreWebView2EnvironmentOptions = New CoreWebView2EnvironmentOptions()
options.AreBrowserExtensionsEnabled = True
Dim env As CoreWebView2Environment = Await CoreWebView2Environment.CreateAsync(Nothing, Nothing, options)


        Me.Show()

        Do While Not waitToLoad
            Application.DoEvents()
            ' Do nothing
        Loop

        WebView2_Main.Visible = True
        Await WebView2_Main.EnsureCoreWebView2Async(env)

The problem is that I just dragged and dropped the control onto the form and did not initialize it via code. It must be possible to set the options this way. If I do it as described above, I get an error message that the element has already been initialized. I have looked in the designer. I do not know where I have to insert that there, if it goes at all ^^ I mean, there it must be initialized, however, you can fit there nowhere the env

` Private Sub InitializeComponent()
Dim resources As ComponentModel.ComponentResourceManager = New ComponentModel.ComponentResourceManager(GetType(Form_Main))

  WebView2_Main = New Microsoft.Web.WebView2.WinForms.WebView2()
  Button1 = New Button()
  CType(WebView2_Main, ComponentModel.ISupportInitialize).BeginInit()
  SuspendLayout()
  ' 
  ' WebView2_Main
  ' 


  WebView2_Main.AllowExternalDrop = True
  WebView2_Main.BackColor = Color.Black
  WebView2_Main.BackgroundImageLayout = ImageLayout.Center
  WebView2_Main.CreationProperties = Nothing
  WebView2_Main.DefaultBackgroundColor = Color.Black
  WebView2_Main.Dock = DockStyle.Fill
  WebView2_Main.Location = New Point(0, 0)
  WebView2_Main.Name = "WebView2_Main"
  WebView2_Main.Size = New Size(1484, 861)
  WebView2_Main.Source = New Uri("https://someurl.com", UriKind.Absolute)
  WebView2_Main.TabIndex = 0
  WebView2_Main.Visible = False
  WebView2_Main.ZoomFactor = 1.0R`

Almost looks like I have to create the WebView2 element manually -.-"
