[Feature]: Need WebView2 support of ARM64EC

[MarkusSchreiner]

Describe the feature/enhancement you need

We require the WebView2 component within a ARM64EC ("Emulation Compatible") runtime.
But currently, WebView2 only supports 'normal' ARM64, x64 and x86.

Using the current WebView2 versions will result in an application crash.

There is a difference between ARM64 and ARM64EC. I can only load ARM64EC or x64 DLLs in an ARM64EC process. And with the x64 WebView2Loader.dll our application crashes.

Are there any plans for official ARM64EC support?
Or is there some workaround, to use the current ARM64 ( or x64 ) WebView2-binaries within an ARM64EC app?

Thank you

The scenario/use case where you would use this feature

An embedded web browser (Edge) is a crucial part of our application. And our application must be executable on ARM64EC machines (at the request of our customers).

How important is this request to you?

Impactful. My app's user experience would be significantly compromised without it.

Hi, @MarkusSchreiner!

It seems that your issue contains the word "crash". If you have not already, could you attach a crash dump as a comment?

WV2 crash dumps are located in a subfolder of the app's user data folder (UDF): <UDF>\EBWebView\Crashpad\reports\. By default, the user data folder is created in the app's folder with a name like <App Exe Name>.exe.WebView2. Refer to Crash Diagnostics for more information.

Thank you for your cooperation!

Unfortunately no Mini Dump was generated.
The only thing I know is, that the call to

CreateCoreWebView2EnvironmentWithOptions()

crashed.
