ASP.NET Core 2.2 is here

Microsoft released ASP.NET Core 2.2 two days ago. This is a smaller incremental release but adds several improvements across the platform.

To list some of the highlights:

• Endpoint Routing – new routing system for better performance and flexibility.
• Improved Health Checks – easier monitoring and readiness/liveness endpoints.
• HTTPS improvements – including certificate management enhancements.
• SignalR Java client – better interoperability for mobile and desktop clients.

Updating an existing ASP.NET Core project is straightforward. Open your .csproj file and then change the target framework like this:

<TargetFramework>netcoreapp2.2</TargetFramework>

...and update package references if needed.

This release is also aligned with .NET Core 2.2, so you get runtime updates such as performance improvements and HTTP/2 support in Kestrel. In most cases, the upgrade to 2.2 is likely a smooth upgrade and a preparation step for the more feature-heavy 3.0 release expected in 2019.
