+I'm happy to announce the release of ReactJS.NET 2.4! The main change in this release is upgrading the ASP.NET 5 (or "ASP.NET Core" as it's now called) integration from RC1 to RC2. Note that currently only the full .NET Framework is supported - .NET Core will **not** be supported until a JavaScript engine such as ClearScript runs on it. To use ReactJS.NET with an ASP.NET Core application, you need to ensure that you are using .NET Framework, by using `net451` rather than `netcoreapp1.0` in your `project.json` file.
