Today we are pleased to announce the availability of .NET Multi-platform App UI (.NET MAUI) Preview 4. Each preview introduces more controls and features to this multi-platform toolkit on our way to general availability this November at .NET Conf. .NET MAUI now has enough building blocks to build functional applications for all supported platforms, new capabilities to support running Blazor on the desktop, and exciting progress in Visual Studio to support .NET MAUI.

gRPC Service with .NET 7
In this video we build a gRPC service with 5 methods: Create, Read (single), List (multiple), Update and Delete. We then employ JSON transcoding (a new feature added in .NET 7) to allow our gRPC service to act as a REST based API. This allows web-based endpoints to consume our service, while at the same time continuing to allow native gRPC clients to consume as well.
