Regression
Was this working before but has regressed? 　＞No.
If yes, what version did this last work on?

Repro Steps

1. Clone this repository.
   https://github.com/MicrosoftEdge/WebView2Samples/
2. Resolve compilation errors
   • Do "Restore Features" in Mixed Reality Feature Tool.
   • remove this line from package.json

     "com.unity.collab-proxy": "2.0.3",
     

3. Open this sample in UnityEditor.
   https://github.com/MicrosoftEdge/WebView2Samples/tree/main/GettingStartedGuides/HoloLens2_GettingStarted/HoloLens2GetStartedApp
4. Attach this script to "WebView"

using Microsoft.MixedReality.WebView;
using UnityEngine;

public class WebViewExample : MonoBehaviour
{
    private void Start()
    {
        var webViewComponent = gameObject.GetComponent<WebView>();

        webViewComponent.GetWebViewWhenReady((IWebView webView) =>
        {
            webView.Resize(webView.Width * 2, webView.Height * 2);
        });
    }
}

5. When I run it, it crashes. (Only Hololens.)

Thanks for reaching out and seems you are running into multiple issues on WebView2 Hololens: #3654 #3652. We will take a further look into them.

@ydev0927 Sorry you are hitting this issue. Do you have a crash dump or stack trace for when this crash happens?

Looks like the "Resize" function is part of the Unity plugin - @michaelfarnsworth

[michaelfarnsworth]

@ydev0927 the resizing issues should be addressed with the latest version of the plugin. Please, try version 0.17.1-pre.5 when you have a chance.

[ydev0927]

@michaelfarnsworth Trying with 0.17.1-pre.5 solved the problem. thank you.

remarks
I used Unity2022.1.15.
Unity2020.3.33+0.17.1-pre.5 is a compilation error.
Unity2021.3.24+0.17.1-pre.5 is an application crash.

Is there a public changelog for the com.microsoft.mixedreality.webview.unity plugin?

[novac42]

As the issue is solved on latest Unity plugin, I will close this issue. For the public changelog redirecting to @michaelfarnsworth for answer. :)

It is not sovled with the current version. Using 0.17.1-pre.5. The UWP app still crashes when using IWebView.Resize(x,y) as previously described.

Tested with Unity versions: 2022.3.7f1, 2021.3.29f1

Crashes always occur when calling this:

webViewComponent.GetWebViewWhenReady((IWebView webView) => { // Do something with this.IWebView });

@ArDevKarl can you run the sample under the Visual Studio debugger to see what exception is being thrown?

I need to correct myselft here. Just found out, that Resize is not the cause of the crash. The problem is, that the application crashes, when I try to instantiate a WebView as a child and/or with localScale zero. I'll open another threat for this issue. Resize works as intended.
