WebView2 WinForms c# Getting Started Errors ?
vmars316 Thanks for your patience. Here are the team's thoughts on your first question:
- You may be using the release package and not the pre-release package of the .NET WebView2
- There is a known bug based on configurations with our previous package. If you upgrade to the pre-release version of the newest package we released last week, it should work. (https://docs.microsoft.com/en-us/microsoft-edge/webview2/releasenotes#10674-prerelease)
If you are still running into issues, you can check out our WebView2-specific feedback repo here:
https://github.com/MicrosoftEdge/WebView2Feedback
And it looks like someone from the team already addressed your second question, but let us know if you still have additional questions!
