With .NET 6 Preview 6 released on Jul 14, 2021, and now Preview 7 released on Aug 10, 2021, .NET MAUI progressed a lot with Workloads, Gestures, Clipping, Alerts, New Layouts, and mainly first-class support for Visual Studio 2022 (with Preview 3.x). But, there is a catch in here. NO item templates for Visual Studio for now :-(.
Thankfully, VS extensions will always be there as a rescue in this sort of situation, and this time too. Have published an extension to the VS marketplace, for VS2022 users, that hosts the MAUI templates.
Update: Users on VS2019 don’t need to feel left out in this, I got you covered with another extension that hosts the Item templates for ContentPage and ContentView, in both XAML and C#, find it in the VS Marketplace – .NET MAUI Project and Item Templates.
