has anybody tried this example
I do not see control in Toolbox and also get "WebView2 could not be found (are you missing a using directive or an assembly reference?)" error.
I also found this:
"This package is necessary for Win 32 C/C++ applications."
in NuGet description. Does it work with C#?
I think, I found solution: update to a pre-release version.
Write In Package Manager Console
PM> Update-Package Microsoft.Web.WebView2 -Version 0.9.579-prerelease
and restart Visual Studio.
