Exactly the same problem. Stacktrace:

Old HWND WebView2 works fine.

Setting SupportedOSPlatformVersion to 10.0.17763.0 in the project file solved the problem

You can also find nuget package microsoft.windows.sdk.net.ref and copy both WinRT.Runtime.dll and Microsoft.Windows.SDK.NET.dll to your build folder.

Hi @merco and @SoulsideJourney, are you still experiencing the same issue, or has it been resolved?

[merco]

@sivMSFT I did as
@SoulsideJourney suggested, but is it the correct procedure or a workaound?

[SoulsideJourney]

@merco Acccording to learn.microsoft.com, WebView2 doesn't support Windows 7 after version 109. So I guess SupportedOSPlatformVersion = 10.0.17763.0 as a minimum version is a requiered setting.

[nhoefer2]

I had the same problem and was able to resolve it when putting this in the csproj file
<TargetFramework>net8.0-windows10.0.19041.0</TargetFramework>

"net8.0-windows" by itself is not sufficient

I have the same problem, and in the release notes there is no mention of it.

I don't know if this dependency has been introduced that now requires a minimum version of Windows 10.0.17763.24 when previously there was none and used the one from TFM (7.0 in the case of .NET9).

In this case there is no official documentation that this control has this dependency and how to fix it. In this page there is not a single reference to any of this and promises that it is simply switching from one control to another and everything works the same because they share the IWebView2 interface.

Or if on the contrary it is a bug and that dependency is not expected.

Same. In my case I had to use the following: <TargetFramework>net8.0-windows10.0.17763.0</TargetFramework>

Using WebView2 nuget version: 1.0.3179.45

Also, I'm not getting NavigationCompleted events anymore. Wonder if this has anything todo with the forced TargetFramework.
