Hi,
My thinclient version is 64 bit, so I have downloaded dev environment of Microsoft edge of 64 bit but it its installed in 32 bit folder. Below is code I used to initialize corewebview2 , there is not error but corewebview2 is still null.
var env = await CoreWebView2Environment.CreateAsync(@"C:\Program Files (x86)\Microsoft\EdgeWebView\Application\87.0.664.52", System.IO.Path.GetTempPath(),new CoreWebView2EnvironmentOptions("-incognito"));
await webBrowser1.EnsureCoreWebView2Async(env);
What could be issue? My dll version is 1.0.674 - prerelease. Dev environment version is 87.0.664.52.
Thanks,
Ajay

I want to confirm some information with you. Can you please inform us what type of project you are developing to run the above code for WebView2? (For example: Windows Forms C# application). Did you try to include the webView2 using Nuget package manager or you are try to reference the webView2 runtime in your project? Please provide the more detailed information may help us to understand the issue in a better way.

I have installed the webview2 version 1.0.664.37 in the Windows Forms application and I just added the webView2 control from the toolbox and set the Source property of it and I am successfully able to run it. Are you adding the above mentioned references for any specific purpose?Also, can you please inform us the purpose of referring to the webView2 like this
var env = await CoreWebView2Environment.CreateAsync(@"C:\Program Files (x86)\Microsoft\EdgeWebView\Application\87.0.664.52"? -

When I pass ebBrowser1.EnsureCoreWebView2Async(null); its gives "Webpath does not exist" error. So I downloaded dev edge and passed its reference. https://learn.microsoft.com/en-us/dotnet/api/microsoft.web.webview2.winforms.webview2?view=WebView2-dotnet-1.0.664.37 link says to initialize corewebview2 we need to do either of 2 steps, I dont want to set source now so using EnsureCoreWebView2Async(env). Is it possible to go on meeting?

Based on my test result, it looks like you do not need to pass the Edge reference.I tested the code below and it works fine.
private void button1_Click(object sender, EventArgs e) { abcAsync(); } async Task abcAsync() { string url = "https://Your_website_here..."; await webView21.EnsureCoreWebView2Async(null); webView21.CoreWebView2.Navigate(url); }Output:
I suggest you make a test on your side and let us know about your test results.

Can you please inform us, how did you assign the webBrowser1 object? It looks like it is NULL.
Is 'webBrowser1' is the name ob the webView2 control?
I suggest directly try to refer to the webview2 control by its name. See whether it works or not.

So I will tell exactly what we are trying to do. Once our form is designed, we are creating object of this from in another code and then access webview2 object. I tried by referring webView2 (Suggested name) but still getting same error.

If possible, please try to provide detailed steps with the sample code. It can help us to reproduce the issue in a similar way as you are doing on your side.
We need to see where and how you are creating the object of the webView2.
It can help us to understand the issue and in this way, we can narrow down the issue.

When I create new project as per suggestions its working, but we have a project where we create object of form and access webview2 reference. See the error we are getting in image attached.
Initially the target framework was 2.0 (refer the image), so we changed to 4.7.2. and created a form and getting error as mentioned.
