Microsoft is releasing WebView2 as part of Project Reunion. They first mentioned this project at its Build 2020 in May. That was just a preview, though. Now, with the technology available to everyone, developers have ‘access to the latest web tech in both existing and new apps. WebView2 lets you combine the ease and agility of developing for the web with the power of building a native desktop application.’
But, with that being said, it’s not available to everyone just yet. Right now, it’s only generally available for Win32 C/C++ apps. It’s definitely coming to other platforms and frameworks, though. WebView2 for .NET support is expected to be released later this year. WinUI 3 will get it after WinUI 3 itself is released out of preview some time next year.
