[Problem/Bug]: WebView2 process not disposing

What happened?

I get this error:

System.IO.IOException: The process cannot access the file 'AssistanceHomeSQLite' because it is being used by another process.

Importance

Moderate. My app's user experience is affected, but still usable.

Runtime Channel

Stable release (WebView2 Runtime)

Runtime Version

No response

SDK Version

1.0.2535.41

Framework

WPF

Operating System

Windows 11

Repro steps

I am trying to execute this code:

string webViewUserDataFolder = WebView.CoreWebView2.Environment.UserDataFolder;

int webViewProcessId = Convert.ToInt32(WebView.CoreWebView2.BrowserProcessId);

Process webViewProcess = Process.GetProcessById(webViewProcessId);

WebView.Dispose();

using CancellationTokenSource cts = new(5000);

try
{
   // Never ends
    await webViewProcess.WaitForExitAsync(cts.Token);
}
catch (OperationCanceledException e)
{
}

// This line fails
Directory.Delete(webViewUserDataFolder, recursive: true);

Repros in Edge Browser

No, issue does not reproduce in the corresponding Edge version

Regression

Don't know

Last working version (if regression)

No response

Start with the WPF reproduction using WebView.Dispose, CoreWebView2.Environment.UserDataFolder, BrowserProcessId, and WaitForExitAsync. Reproduce the failure on Windows 11 with SDK 1.0.2535.41 and determine why the process remains active; done means the user data folder can be deleted after disposal without the file-in-use error.
